Am I the only one who thinks of smartphones and tablets as silent computers?

Granted, they can't do what this person's high-spec workstation can do, but they do most of the computing tasks most people use (used) noisy fanned computers with clacking disks for and in many cases do those tasks better.

And unless I'm just losing my hearing, my smartphone is completely silent as long as I don't accidentally press the Golem Invoker, er, Siri button.

There are plenty of silent/fanless Coffee Lake based industrial NUCs, too.

linsomniac 253 days ago [-]
I was kind of excited about this build but then I saw your comment and remembered that was a much better option.

4-6 months ago I built a new workstation for work. I had used one of those Corsair closed loop water coolers with the prior build, so I set one up on this guy. A month or so later my workstation was running really sluggishly, and I realized it was drastically throttling the CPU because of heat. I installed some software to spin up the fans on the cooler to keep it down under 100C, but now it'll get kind of loud when I run much heavy CPU.

Now, this is a pretty heavy duty workstation, 64GB of RAM and 3 displays. But, if I were doing a new machine for home to be quiet, I think it'd be a NUC. Then I'll put the box that has the 6 drive ZFS array in a closet and call it good.

If you want something slightly more modifiable, Compulab makes passively-cooled screwdriver-openable boxes at basically all levels that it makes sense.

Their highest end is available with ECC ram and a discrete graphics card:

And the lowest end fitlet2 can be configured with an atom in a reasonable configuration for around $300 (it's $130-$200 for case/cpu/motherboard depending on which CPU you configure).

linsomniac 253 days ago [-]
I had looked at the NUCs a few months ago, and just remembered how hard it is in their product page to find something that will support 3 monitors. Looks like only the highest end models will do. I'd be tempted to build my own again, especially for my home office where I can put it in a closet next to my desk. The NUC product page lets you select requirements and then seems to give you a list of products that don't match.

Gigabyte also has their BRIX products, which are similar to the NUC.

I was at a hotel this weekend and at check-in they had a monitor with a "ThinkVantage slotted in the back of the monitor, that might be a nice setup.

TheCapeGreek 253 days ago [-]
Ha, the entire team at my previous job were using NUCs. Nifty little buggers. In the summer it would heat up quite a lot (not yet to the point of damage I suppose) and I couldn't even turn it off without burning myself if the PC froze.

Eventually I just bought a cheap USB desktop fan and ran it facing the NUC.

uglycoyote 252 days ago [-]
I'm using a NUC for a quiet home PC that I do mostly browsing but also some light web development on. Although it's mostly silent, I haven't been too impressed with the performance of it. It was one of the top of the line models in 2015, an i7-5557U. I was surprised to find it's quite a bit slower than my 2013 Macbook Pro 2.4 Ghz i5. On the Geekbench profile the MBP got almost 3x the single-core score of the NUC and 1.7x for multi-core. Real world performance of the older macbook is noticably faster.

It has made me think that instead of getting a NUC, for a quiet desktop system I should have just gotten a second used MBP and ran it permanently docked in clamshell mode with the monitors and keyboard attached. (with the added benefit of being able to go portable when I want to)

Neither the NUC nor my MBP is completely silent but for my purposes I find that I seldom tax either of them enough to where the fans become audible enough to be annoying. Still, I do find the difference in performance between them to be apparent just in things like iteration time on web development and IDE responsiveness.

My iPhone 7 Plus has some crazy coil whine. In a quiet room you can hear it. I can hear incoming notifications being processed before the alert goes off!
krrrh 254 days ago [-]
Is this only when it’s plugged in? Could be a bad cable or charger. I had an iPhone 5 that had a super touch digitizer when plugged in, and I finally narrowed it down to cheap third party cables. Otherwise I think I would be doing a sit-in at the nearest Apple Store until they replaced it, that would drive me nuts.
cptskippy 254 days ago [-]
The transceiver powering up is actually noisy. I had a Nokia 2100 series in the late 90s that generated enough emi to distort a CRT if it was sitting next to it.

You could hear the whine from across the room a few seconds before a call would ring through.

lscharen 253 days ago [-]
Heh. Back in the 90’s in college I would keep my phone on top of the monitor I was sitting at exactly so I would see the monitor juke just before the phone connected.

People always asked how I managed to answer the phone so fast. Electromagnetic Supplementary Perception, of course.

bigiain 254 days ago [-]
Heh - same sort of timeframe - probably a Nokia 8210 though - I could reliably have my Apple hockey puck mouse "crash" if my phone got an incoming call while it was sitting on my desk in a loop of the usb cable for the mouse. It'd just stop working, and need unplugging/replugging to get it working again.

It was clearly electromagnetically "noisy", but I do't recall ever having heard any on my phones make any unexpected audio noise... (My old-and-abused rock concert and motorcycle weary ears probably can't get up as high as inverter whine any more though...)

Pretty much all cellphones would do that to CTRs. They would also go directly into the audio circuits of cheap amplifiers, to the point where you could "hear" a text or call incoming before the phone made any kind of notification.
Cthulhu_ 253 days ago [-]
You know, that reminds me on how we don't really hear any speakers making odd noises when there's an incoming call anymore. Probably because phones operate on different frequencies nowadays.
lb1lf 253 days ago [-]
-I presume transmit power has been lowered significantly as coverage has improved, too; your cell always transmits at the lowest level it can get a reliable connection with to preserve battery life. This should reduce interference considerably.

Also, GSM phones used TDMA (keying the transmitter on and off to occupy one of -hm- eight, I believe - time slots on a given channel.)

This is practically asking for EMC issues.

LTE, on the other hand, transmits continously (I believe - I do not work in RF engineering anymore, but try to read up on new tech every now and then.:) - much less interference-causing than the constant on/off of TDMA.

Baeocystin 254 days ago [-]
I'd say a good half of the smartphones I've owned over the years have had audible something, even when not plugged in and supposedly silent.

Some were barely noticeable, while one in particular (a Droid Turbo) was so loud I could hear it getting ready to receive a call from another room. This was regardless of whether they were plugged in or not, although charger whine was its own separate issue.

Thankfully it does seem to be getting better over time- my current S8 is, as far as I can tell, genuinely silent.

mozumder 253 days ago [-]
This happened on TDMA systems like on T-Mobile and AT&T. (Verizon & Spring were CDMA).

There's a TDMA modulation frequency at 217Hz and this interferes with all sorts of nearby audio devices. CDMA and WCDMA phones have a much broader interference spectrum, which is why you don't hear it much anymore.

nsxwolf 253 days ago [-]
No, this is all the time. It is only quiet when the phone is idle.

I considered returning it, but I find it charming. I miss the days when you could tell exactly what your PC was doing by all the sounds it was making, and I find dead silent electronics to be elegant but a little sad.

TheKarateKid 254 days ago [-]
It could also be the earpiece/speaker turning on and having static noise right before the notification sound is made.

The easiest way to experience this is to plug in headphones and hear the clicking before/after a sound is made.

nsxwolf 253 days ago [-]
The sound is loudest if I hold it up to my ear right behind where the SoC is. It generates a unique pattern of sound based on activity, such as running your finger over the touch screen. It's not just when sound events are about to play.

Back around 2001 I took my desktop build (Celerin 300A oveeclocked to 450MHz), installed a giant passive heat sink on the CPU and PSU, put in an 8MB IDE flash drive, and network booted off a server in my laundry room. I thought I was finally noiseless. But the end result was worse. I had coil whine out of my power supply any time CPU usage ramped up. If I was in the same room, I could tell whenever my email pinged the server or if a cron job ran. It was both instructional (why is my cpu ramping and I’m not even logged in?) and really annoying.

I bought an Asus "zenbook" ux305 for this reason. It uses an Intel core M processor, which idle around 800mHz but turbo boost to around 2gHz, which I believe have been discontinued.

I was worried about performance, but it has been very acceptable. It depends what you need it for, but I can run 2 monitors, a Linux VM and atom all while streaming HD video. Or I can do light web browsing for 10 hours on battery[1]. I love it.

On the rare occasions I need more power, I spin up a spot instance.

First line of the pertinent Wikipedia article: "The MacBook is a brand of notebook computers manufactured by Apple Inc. from May 2006 to February 2012, and relaunched in 2015."

And yet, in a post referencing a fan-less "Macbook" it's almost certain that the "Macbook" in question is the only fan-less laptop Apple produces, which is coincidentally called simply "Macbook."

It's unfortunate that Apple has confusing brand names, but the fact remains that the Macbook indeed has no fans so the original comment who hears fan noise is obviously using a different model of laptop.

mcv 253 days ago [-]
Of course there are Macbooks without fans, but the claim that "the macbook has no fans" is a bit too broad and generic to be true. Macbook Pros are also called Macbooks. Older Macbooks are still Macbooks (they seem to be pretty durable).

Xylakant 253 days ago [-]
Mere physics says it won’t. It’s always possible to pack more performance in a larger package, even if it’s just because you can more easily dissipate heat on a larger surface. iPhones are amazingly powerful and might just be sufficiently powerful for everyday computing soon or even right now, but they’ll never surpass anything that can accommodate a larger die.
davedx 253 days ago [-]
Physics doesn't drive CPU development, it just sets the absolute limits.

Apple have put faster chips in their smartphones than in their laptops.

Xylakant 253 days ago [-]
Geekbench scores are interesting, but not necessarily translate straight into real-world performance. Intel CPUs have a much richer instruction set for example. Peak performance vs sustained performance is another issue. GPU performance, disk size and speed, available RAM, battery time at a certain usage etc. are other performance factors. Apple could decide to put faster CPUs into its macbooks at the cost of less battery time.

This is all alluded to in the article and the macrumors post that the article is based upon, here are some quotes:

> "Sure, that doesn’t mean the A11 Bionic can do all the things a desktop CPU does."

> "Though the iPhone X and the iPhone 8 offer impressive Geekbench scores, how that translates to real world performance remains to be seen."

There's no question that the iPhone chips deliver amazing performance, but there's a reason people still lug Macbooks around.

zelos 253 days ago [-]
It does seem like something is missing in the comparison. High end x86 CPUs draw something like 30W idle, which would drain an iPhone X's battery in minutes. Do Apple/Arm really have some magic technology that makes their CPUs orders of magnitude more power efficient?

Geekbench always seems like an odd benchmark - the variability between runs alone is kind of odd. If I could run a compiler on an iPhone, for example, would I really see similar performance to my MBP?

Xylakant 253 days ago [-]
The CPUs in MacBooks are mobile CPUs that certainly don’t draw 30W idle. You’d drain the battery faster than you can charge it :)
mrguyorama 253 days ago [-]
One thing to note, x86 is known for being spectacularly inefficient for mobile workloads. It's not magic that makes an ARM CPU more efficient, it's just different design considerations. For an example of this, check out the Intel Atom line of processors[0] which were mostly x86 processors but designed to be mobile and power sipping. Whether they were successful at that, or in terms of performance, I'm not sure. But they get down to single digit TDP, which is how many watts of power you can expect one to use while under load.

Same, some feedback that something is happening is great. This is what annoys me the most about macbooks, they give 0 feedback when they're off.

Black screen, and you kinda have to push the button for an arbitrary amount of time and wait for an arbitrary amount of time until there's any feedback.

Whereas on a normal computer, a light goes on and the fans start spinning, not because it's useful but just to indicate that it's on now. It's a miracle.

It's more of a pain to set up during a meeting than a dedicated docking station would be. It also doesn't currently charge the phone (although there are ways to modify it to do that). It's nice for novelty but a little unwieldy. Using an OTG cable with a keyboard with a built-in hub reduces some of the cable clutter.

No, but a smartphone is not a computer.

Smartphones are capable of computing and are sometimes very powerful, but the analogy is totally out of wack in my opinion.

If you can live without using an actual computer, it means you don't really need computers. You can check your email and browser the web on a Kindle, on your TV, or even your car.

Everything is a computer, then.

I think a computer is a productivity tool. Smartphones (and I'd definitely say tablets, too) are to consume content, not produce it. Some companies (most notably Apple I think) believe otherwise, but I think they'll have to come to realize that smartphones and tablets are horrible to produce most kinds of content.

bschwindHN 253 days ago [-]
A smartphone absolutely is a computer. It's maybe not a "productive" computer for a lot of workloads, but it still carries out operations and produces output based on the input it is fed.

You're just making up your own definition of "computer" and then claiming a smartphone isn't one because it doesn't match your made up definition.

Certainly in the rough sense of 'Turing machine' a smartphone is clearly a computer. And, even in other senses, I can connect a keyboard to my S5, open up Termux, run ffmpeg, open up Emacs --- all on the smartphone itself, not through ssh or anything. But it's hardly as productive as a regular laptop or desktop, of course, but that's largely due to screen size, lack of keyboard (or lacklustre keyboard), and weakness of processing capacity compared to a desktop/laptop.

Totally agree. That's where the line is drawn I think.

Those are servers.

If we want to classify devices, we need to group them somehow. Otherwise we call them devices and call it a day.

zingmars 253 days ago [-]
His old DOS machines certainly weren't servers. Not having a GUI does not make a machine a server and having a GUI does not make a computer not-a-server (especially since we have graphics chips inside CPUs now).

Servers are still computers.

We already classify them: smartphones, tablets, laptops, desktops, servers are all groups of computers.

annabellish 253 days ago [-]
I don't know about iDevices, but this is very much supported on a lot of Android phones. Samsung's lineup even has it as a bullet point feature, and they sell docks which let you connect your phone to a screen, peripherals, and switch to a mouse-oriented UI without having to do _anything_ weird.

At that point, you're running a mouse-centric, multi-window OS with a wide array of software, that can run basically whatever you want.

So that's a computer, definitely, right? When does it stop being a computer? If you disconnect the display? Is it using a stylus instead of a mouse? Maybe the software keyboard instead of a hardware keyboard? (But then is the MS Surface not a computer when you detach the keyboard case?)

mc808 253 days ago [-]
Even though you're technically wrong (the best kind of wrong), I can see where you're coming from. Even microcontroller ICs without enough memory to store this comment are real computers and are silent, but if you say you've built a silent computer and then unveil some Arduino contraption, expect eyes to roll.

That said, I still think smartphones qualify as computers even by your productivity definition. Newer smartphones would sit somewhere above older netbooks on a ranking of overall utility.

In the past when I tried to build a silent PC, I found that even after removing / stopping all the fans, there was still often an electronic humm or buzz left over. That is when I gave up.

Later I changed desks to one that had one of those built in computer cabinets made of thick particle board. That did as much to silence a pc as all the tens of hours of effort I had put into meticulously researching and specc'ing the build before.

loser777 254 days ago [-]
This type of noise is arguably worse than that produced by a well-managed fan setup. If you have fans that spin at a constant RPM, you can fairly easily tune out the noise. Coil whine will vary depending on the load of the system (e.g., when you start/stop scrolling a web page), making it much more difficult to tune out.
RowanH 254 days ago [-]
Never heard coil whine for years and years decades infact of PC building. Until last year I got my shiny new fancy pants blast furnace, (aka GTX 1080 TI), which has near dead silent fans at idle/light loads. The minute that bad boy starts working an obnoxious screeching/whine starts.

Super annoying compared to the rest of the build being a beast of a machine and watercooled that's so quiet I'm more likely to hear the noise floor on speakers than the PC (which is on the desk, next to said speakers).

corysama 254 days ago [-]

developer2 253 days ago [-]
Coil whine with graphics cards is such a frustrating experience, because there is no informed consensus as to what the underlying cause truly is. Everyone has their own anecdotal reason:

a) Maybe coil whine is an intrinsic factor in the manufacture of graphics cards, similar to dead pixels on displays. "Luck of the draw" when obtaining one is the only way to win. Cycle through RMAs until you get one with little to no coil whine.

b) Or, it depends which company you buy from: each of Asus, EVGA, Gigabyte, MSI, Zotac et al are supposedly better or worse than the others.

c) Or, it's not a problem with the GPU at all; rather, it's an indication of a poor quality power supply (PSU).

I've never seen an informed analysis from an industry engineer who has a goddamn clue what they are talking about. NVIDIA could probably enlighten us all with an exact-science explanation, but that seems unlikely. My uneducated guess is that the situation is closest to option 'a' above, and that rejecting units for coil whine during quality control would drastically reduce production yield.

ovao 253 days ago [-]
Yeah, I don’t see NVIDIA or AMD drawing any attention to product flaws, particularly if the end-user solution is “RMA until you get a good one”.

jaytaylor 254 days ago [-]
My GTX 970 does the same thing. It is incredibly annoying.

Fortunately it happens when at high load, which is while playing games. This doesn't help for quiet scenes, though.

Is there a way to fix this sound in video cards? I'll have to investigate.

ovao 254 days ago [-]
Coils emit a relatively high-frequency sound, so your best bet is a case with thick panels, that’s fairly well enclosed, and has some acoustic dampening.

Most cases made today don’t have any significant dampening material. It’s pretty trivial to add some to the panels without significantly affecting cooling capacity.

cellularmitosis 254 days ago [-]
Alternatively, if you wanted to really dig into this, you could try to find every switch-mode power supply and replace them with (much less efficient) linear power supplies. You'd need a larger water-cooling system though.
hatsunearu 253 days ago [-]
Is this a joke?

That would require making your own GPU PCB, and maybe a year's worth of studying on electronics and power supply design.

cellularmitosis 253 days ago [-]
Not really. More likely just desoldering a couple of key components and soldering in a few wires to a dsughterboard with a linear regulator.

A year’s worth of power supply design? Have you looked at the LM7805 datasheet? The circuit is one regulator and two capacitors...

magicalhippo 252 days ago [-]
Have you looked at the current requirements for CPUs and GPUs? We're talking 100A or more. Even if the input was 3.3V, which it isn't, a linear regulator down to 1.1V would have to dissipate 220W or more. You'll need a bigger heatsink for the linear regulator than for the CPU...

And designing a 250W-capable linear regulator is not as simple as just hooking up a LM7805.

So with a modern CPU and GPU, your talking ~400W of power to the actual components, and nearly 500W wasted in the linear regulators. This of course also means you have to get a 1000W PSU as a bare minimum.

hatsunearu 242 days ago [-]
Here's the problem: not only do you have to dissipate 200W+ for your pass element, you need to drive it ultra fast with an extremely fast analog circuit that can withstand the massive magnetic fields (which pretty much means you need a PCB).

Yeah and good luck driving a 200W linear element (if it even exists, lol) with a few op amps--the driver which should deliver a few amps into the gate/base of the pass element, which in and of itself is a pretty difficult challenge.

hatsunearu 242 days ago [-]
old thread but

LMFAO you can't be any more wrong. You need /much/ more careful design to get GPU-compliant performance. The dI/dt on modern ASICs are insane, and you need an insane regulator to deal with it.

I've had a GTX 460 and a GTX 660 Ti before, and once I upgraded to a GTX 970 i was disappointed by the coil whine.

Guess we'll have to live with the fact that the tech cannot keep up with the demand and quality, resulting in more 'unstable' electronics.

I had a Logitech G500 with awful coil whine and the opposite problem: it would stop whining when moving and start when idle.

Some noise, depending on the texture can be even pleasuring.

coil whine is highly unnerving while low fan sound is relaxing.

we like stimulus, the clicky keys of my old hp48 is neat, the insertion sequence of pioneer 32x slot-in cd drive was amazingly subtle; not long ago I revived an old HP tape drive, the tape rolling and the head gear was also beautiful.

Also, it was as cute as informative, it's a clear state change side channel. Often software notification about hardware are decoupled so much that you don't trust it; plus they're invasive, unlike a tiny led, a click, a tiny motor ramping up.

Which is why I have been putting off getting a new laptop for years now. Most seem to suffer from coil whines and I can't stand it (to the point I ended up using an old eeepc 1000he rather than a brand new 16 inches VAIO some years ago).

I've switched to Fractal Design cases with their heavy sound-proofing and been thoroughly impressed. I use Corsair RM750 which never powers its fan on, and I used to have a all-in-one water cooler for the CPU, but I moved to a Noctua design with a large 140mm fan. The water cooler had a 120mm fan that I replaced with a 120mm Noctua--but it was too close to the rear vent of the case, and thus noisy.

However my graphics card (RX 480) is quite loud, and one bearing is making noises.

But the Fractal Design case has really dampened the sound. For my home server, it's using a RM500 (which also never turns the fan on), and a low-profile Noctua CPU cooler. No other fans, but I do hear the 6 HDDs spinning and seeking when it's real quiet in the room.

I don't hear any coil whine, except when using headphones plugged into my desktop's speakers--probably the result of the speaker system's power supply. Klipsch ProMedia, if you're curious.

stcredzero 254 days ago [-]
I have one of the Corsair budget quiet cases under my desk. I can attest that it has excellent bang for the buck, for being a basic black case with useful soundproofing/absorption.

As far as noise reduction for CPU cooling, I'd suggest buying more air cooling than you need for a modest TDP CPU. Between that and my fanless Seasonic power supply, and SSD, the only noiseI can ever hear from my machines is from the GPU.

GordonS 253 days ago [-]

I had a Corsair H50, it lasted about 5 years or so. The pump died on it. It was actually quite annoying to track down. At idle it would run for an hour or two before shutting off. But start a game it would only last a few minutes.

Seems obvious in hindsight, but I had no fan (pump) speed warning or anything.

The case matters a lot. I've got a Fractal Design Define C, which dampens a lot of noise. Supposedly the R5 is even better.

This was my second silent PC. The first one still had moving disks, but I went for as few fans as possible, and had passive coolers on the internals. This time I did the opposite: lots of fans, but have them spin as slow as possible. This works very well.

But coil whine and electronic hums are easy to overlook when you're choosing parts. It's worth looking at not just the fans and the power use (more power needs more cooling), but also the quality of the electronics.

I don't need my computer to run at a cool 30°C all the time. The hardware can run very hot without any issues. And when all the fans eventually kick in under load, it will always keep under 70°C anyway.

Imo the AMD drivers are way better than Nvidia's drivers. They're included in the kernel and therefore open source. Compared to Nvidia's proprietary drivers that have horrible support with a lot of compositors and lack support for DDC/CI over DisplayPort. The Nouveau drivers are better (slower performance but better compatibility), but are unable to change the clock speed (and are set to the minimum).

The AMD drivers "just worked". Selling my RX480 for a GTX 1070 was the worst decision I made when it came to compatibility. Now I can't even get Vsync to work with this Nvidia crap.

Well it's a good thing nvidia is catching up on being horrible. The 367.xx driver's dkms module doesn't even compile for me on Ubuntu 16.04 anymore, and later drivers make some gstreamer-based apps stutter a bit.

And Windows is behaving weirdly as well since I installed the latest drivers. Black bar on top of full screen programs after waking from hibernation, The HD audio driver not letting pulseaudio start (I need it to get sound from WSL) and crashes when multiple 3D accelerated VMs are open. And restarting the GPU driver (with either the shortcut or through device manager) is what solves all the issues and they only occur with the latest driver.

And the crappiest part is that there's nobody that can help. Getting someone from nvidia to respond on their forums is basically luck, and I'm not a huge company that can get their reps to get someone to help me.

The open source drivers of slightly old GPUs are ok. Not that good, but not bad either. And they are open, so they will come well integrated with your distro.

What puts AMD GPUs in a weird situation where you can expect them not to work very well when they are new, but to improve until you can forget about them. (The inverse of the NVidia GPUs, that work ok when new, but slowly loses compatibility with time.)

One can make a passive build much more powerful.

NSG S0, once out, will most likely be the go-to case for such setups. Until then, an HDPLEX H5 is cool.

My desk has a H5 on it, housing an i7 8700 (non-K) and a GTX 1060. The TIM under the heatspreader is replaced with Thermal Grizzly Conductonaut and Thermal Grizzly Kryonaut is used as every other TIM that the case setup needs. The CPU is on stock clocks with a voltage offset of -30 mV. The GPU has the power target reduced to 90% and clocks increased by 130 MHz, so that it is effectively undervolted as well. The PSU is a Seasonic Ultra Prime Titanium 650. Prime95 with AVX throttles really, really fast, under a minute, perhaps, but is a very unrealistic load. Non-AVX stress tests and FurMark take a while to start throttling (20 minutes?), as the thermal capacity of the aluminum case is quite big. After hours of gaming, the GPU and CPU float around 80 C while providing full stock performance. I don't do 3D rendering (other than in-game) or video en/decoding, so have not had long, real-world, full loads to see how temperatures behave with those.

From the discussion I've had and forums I've read, I think that people are afraid of putting more power in passive cases and having their components at "high" temperatures, despite those being rated for them.

>Prime95 with AVX throttles really, really fast, under a minute, perhaps, but is a very unrealistic load

I suppose blender would thermal throttle the cpu as well. If you run any non-Xeon/non-Laptop Intel chip (greater than 2k series) and care about temperatures - delid the bugger. (Xeons are soldered, laptop chips don't have IHS). Intel uses something that's worse than toothpaste, plus tons of glue between the die and the IHS. If you see temperature deltas under full load more than 9-10C between the cores, the thermal paste between the die and the IHS might have missing spots or have dried out. In your case removal of the IHS altogether would provide decent results.

You might wish to check the VRMs, they are rated at 125C but if the case is hellishly hot inside, they might not be able to dissipate the heat.

Misdicorl 253 days ago [-]
Somewhat unrelated, but maybe you can shoot me down since you seem to have some experience?

Metal is an incredibly good conductor on its own, and the properties of thermal paste (typically) are just barely better than air. So long as your cpu and heatsink are fairly flat surfaces and mashed together physically, it seems like either forgoing or having the absolute minimum amount of paste is ideal. I've used a razor to leave an absolutely minimal layer of paste (e.g. filling in sub-millimeter surface structure) on my latest build, and cpu temperatures are well within a reasonable range. But I'm also not trying to OC the cpu or anything.


xxs 253 days ago [-]
>...and the properties of thermal paste (typically) are just barely better than air.

I am not certain how you have managed to come to such a conclusion. Thermal conductivity of air is around 0.03W/(m·K)[0]. Good thermal, non-conductive paste is like 12.5W/(m·K)[1] (or 400 times better than air). Conductive ones are in the region of ~40-80 W/(m·K) and Aluminium is 237W/(m·K). Also air also expands pushing the cooler and CPU away.

Normally you if choose between "too much" and "too little" paste, you pick the former. The pressure pushes out the unneeded amounts.

[0]: [1]:

Misdicorl 253 days ago [-]
Don't, you need to multiply the raw conductivity by the linear distance occupied by the thermal paste? I presume that distance will be at least two orders of magnitude larger than that occupied by air in a metal contact only setup.

I would be extremely surprised if increased pressure due to air at higher temperature played any role whatsoever unless the bolts connecting the heatsink and cpu were very loose. If anything, I'd expect the increased conductivity of air at higher temperatures to dominate.

I'd also expect there to be effects at the metal-paste and paste-metal interfaces which reduce the effective system conductivity (i.e. phonons are much more likely to reflect in this scenario than in a metal-metal interface).

baseethrowaway 253 days ago [-]
It's very impractical/expensive for mass products to make the surfaces in question so flat that no thermal paste would be needed. Many tests and reviews have been done. Even if top-of-the-line coolers came with perfectly flat surfaces, Intel's heatspreader is not -- otherwise it would cost so much more. Also, heatsinks can be applied with a lot of force, which usually pushes out the "unneeded" part of the thermal paste. In a bind, even lipstick, toothpaste, chocolate and other silly compounds work better than nothing, so I'm not surprised that you're getting ok results even with a touch of thermal paste.

A fun thing to try is using a modern low-end CPU (latest i3s, Pentiums, Celerons) without its cooler. Not advised by Intel, of course, but you might get into your OS of choice even before it starts throttling. I'm somewhat comforted by the fact that a CPU automatically powers of once it reaches something above 100 C (103 maybe?) and throttles a few degrees before that. Those temperatures shouldn't leave the silicon damaged.

In practice, thermal paste is a must. If you don't like those (I personally don't, they get everywhere by accident and can be tough to remove), try getting an IC Graphite Thermal Pad which is reusable and rivals really good, if not the best thermals pastes, according to the limited number of reviews I've seen. I think that its practicality beats better results in non-highest-end applications.

Its really not that hard to create flat surfaces- anyone with a lathe, a hard cutting instrument, and a bit of fine grinding material can probably get a contact bond between two pieces of metal.

Blender might throttle. Does it come with benchmarks/tests that I could use to gauge thermal performance?

The CPU is delidded! I've got another i3 4300 delidded as well running under a NoFan CR-80EH. Delid + Conductonaut + Kryonaut made the difference between throttling vs hovering around 90 C in FurMark + Prime 95. When integrated graphics aren't used, the CPU runs cooler, of course, and didn't throttle with MX4 thermal paste and no delid.

I do fear that VRMs are running too hot. When selecting components, I picked those that come with some heatsinks on VRMs at least. The motherboard is an AsRock Fatal1ty Z370 Gaming-ITX/ac (non ITX motherboard wouldn't fit in the case anyway with an ATX power supply). The graphics card is Gigabyte's cheapest offering and has a small sink across the VRMs. I'm hoping that undervolting will help keep the VRMs in check.

emptybits 254 days ago [-]
Clearly a work of passion and I appreciate OP sharing.

I enjoyed earlier days of "Silent PC" building, ten or fifteen years ago. For example, building a silent tower or desktop for a DAW or softsynth back then in a recording/studio environment required some ingenuity. SSD? Not on a hobbiest budget. I recall one build, not mine, fully immersed in a bucket of oil (mineral?) for passive heat dispersion.

Today, as a new reference point, any MacBook Pro within the last few years may qualify as truly silent for many people's everyday usage. It does for me. And when I do heat up the CPU/GPU with heavy tasks, the fans spin up but then they go away completely as soon as the hard work is done. Back to silent.

No more spinning platters or crappy fan bearings or poorly engineering airflow nowadays. :-)

There's no hacker pride in buying off-the-shelf, so the performance bar for DIY is higher. Progress!

tp69 253 days ago [-]
I'm glad you enjoyed the post. My first silencing attempt (in the early 1990s) was to seal a hard disk in what amounted to little more than a couple of oven bags, custom-make a long IDE cable, and then — literally — dangle the drive in a bucket of water that was under the desk the computer sat on. That ended poorly, with thermal cycling inducing microfractures in the bags, which resulted in leaks, a dead drive and a blown controller on the motherboard. Ah well, we live and learn. Take it easy.
patentatt 252 days ago [-]
It used to be fun trying to silence a computer. Figuring out which HDDs were single-platter, undervolting processors, finding low-rpm fans, etc. used to be a challenge, and have great rewards for those of us who care. Now, check out, hasn’t been updated this calendar year. In some ways I miss the old days, but most modern laptops and even desktops are reasonably quiet, and full silence is easy to achieve.

This says that a completely silent computer would be 0dB. But it's a logarithmic scale, so I think it should say -Infinity dB.

This is admittedly pointless pedantry.

klodolph 254 days ago [-]
Silent means that it has no sound, but "sound" either means the sensation of perceiving vibrations, or the actual vibrations that cause the sensation. 0 dB SPL is the threshold of hearing, so it is "silent" in the first sense.

Strictly speaking.

jiveturkey 254 days ago [-]
He’s using the term incorrectly to begin with so corrections aren’t really possible.

Of course it can’t be completely silent. Heat generates air movement which is “sound”.

By 0dB he means 0dB SPL which is give or take correct.

contravariant 254 days ago [-]
If the air moves at a constant speed I don't think you'd get sound. Any fluctuations probably won't be in the audible spectrum, although whether that still counts as 'silent' is more of a philosophical question.

calibration263 253 days ago [-]
To be more pedantic, it's probably safe to assume this is not even 0dB. Most people would probably consider a computer under 25dB-30dB as "silent" since most rooms background noise are around there.

Linus did a silent PC build which even in a sound proofed case and at idle was about 14dB and broke 20dB under load:

Even the high end microphone used to record the sound level in this video produced it's own 7dB of noise.

ovao 254 days ago [-]
It may register below 0dB SPL (in an anechoic chamber, anyway) depending on the manner in which it's measured, which is a complex discipline in itself. Sound pressure dissipates over distance, for example, so the distance at which the measurement is made has bearing, as does the angle at which it's measured.

(This is unabashed pedantry. But I'm on my lunch break, so...)

20 to 30dBA is probably the base noise level of most environments.

dragontamer 254 days ago [-]
So these sorts of builds are way harder than they look. You need to spend a good amount of time planning out motherboards, and willing to go back to the shop to buy another motherboard (because this motherboard might have a big honking capacitor where you expected to run a heat-pipe).

So you either need to carefully look at pictures / guestimate the location of components, or hope that someone else on the internet has figured it all out for you. Alternatively, you could just be ridiculously lucky.

But I don't really believe in luck personally. If this guy has been doing these builds for as long as he claims, he probably had a fair bit of thought go into the particulars of this build. The kinds of thoughts that don't go very well into blog posts because they're uninteresting (but very important). Like, does X combination of components fit or do I do Y instead?


With respect to the build itself: I'm surprised he was able to get 60+W CPU and a 60+W GPU in there. Most silent builds I see basically use laptop parts (30W or less) to keep the heat down.

32gb of RAM will be plenty, and 8 Zen-cores is plenty strong. The GPU is a bit weak for gaming, but he should be able to play plenty of the lower-end games without much issue, even at 1080p / 60fps (probably Overwatch for example). He probably can't run Witcher3 at 4k on Ultra, but such a GPU would blow out his thermal-design completely.

tp69 253 days ago [-]
Yep, it took weeks to finalise the parts. I had to contact multiple vendors and get them to check component heights, track down motherboard layouts, compare review photos from different angles, plan heatpipe runs, resolve conflicts with VRM heatsinks and power connectors, watch assembly/review videos over and over again, scrutinise manuals, determine hardware/OS incompatibilities... probably well over 80 hours of work before I could even order the parts.

But, like you say, even though I had done all that, there was still the possibility that I might have missed something and would need to return/replace some parts and rework the plan. My mouse hovered over the "Order" button for quite a while before I finally committed. An anxious moment.

Virtually none of that methodical and boring research/prep work made it into the post — it's just not that interesting. Necessary, yes, but not something that the vast majority of readers would want to read.

The setup should be able to handle a 105W CPU and 75W GPU. At this point 65 + 75W is confirmed. When I OC the 1600 I should be able to verify up to ~95 + 75W.

The strategy was to start with a really well engineered passive case, then select components that could be pushed right up to the thermal limits. It's worked well so far. I'll keep publishing all of my test results for those that may be interested.

All of my raspberry pi's are completely silent.

On a more serious note, would it be possible to achieve said silence without too much compromise by some variant of water cooling, with a good sized reservoir? And use the heat to drive circulation rather than a pump?

bluGill 254 days ago [-]
Maybe, but it is tricky.

Because there is no pump the water will flow much slower, therefore you need much bigger pipes. Think at least 3x the diameter you would think you need.

Also because you are depending on thermo siphon you have to ensure you have to ensure the water flow works with gravity. The heat source must be at bottom, and the radiator must be at the top. You don't get any flexibility go around something that might be in the way, the pipes must always be sloped in the correct direction.

If you are using anything other than water you need to pay attention to specific gravity (and how it changes with temperature), and viscosity. Probably something else that I'm not thinking of.

It probably can work. I have an antique tractor that uses such a system. A 2.2L, 16hp engine, has 24L of coolant, and the pipes between the engine and radiator are noticeably bigger than my truck with a 7.3L 250HP engine. Remember that this was designed to run at just under the boiling point of water (antifreeze is too modern). You probably want your computer considerably cooler, which implies even larger systems than a similar active one.

Yes, just use a flat (i.e., no high fins) passive cooler on the CPU (this won't fit with stock parts), lay the motherboard flat and submerge about 1cm deep in a refrigerant boiling in the range (max room temp 5K) and (max healthy cpu temp -20K). Flourinert and Pentane are suitable, the former is really expensive and the latter as flammable as gasoline. If you replace the cooler with a 1mm copper plate and use a pump to archive a flowspeed across the cooler between 5 and 20m/s, you can get crazy overclocking. You might get subzero clocks without any active refrigeration. The benefit is that all your ancillary components are cooled too, and you have superior performance with a pumnp, and even performance without one. Ensure some radiator with gravity-backflow gets the vapor, e.g. just use a central heating one above and ensure liquid can't pool in the piping, and that that is not too narrow.

Sounds overly-complicated (but fun). Why not just build in an aquarium and submerge it in mineral oil?
IronBacon 253 days ago [-]
From what I recall mineral oil has long term effects on the HW, or in other words, I think I've seen some pictures of mineral oil cooled MBs with degraded/melted plastics. And the oil it's a logistic mess.

Instead the other day on Youtube I don't recall how I landed to a 3M infomercial about their Novec dielectric liquid used for immersion cooling. That stuff looked interesting, but they didn't spilled (pun ^__^;) details about cost or health issues tho.

namibj 253 days ago [-]
The difference between Novec 649/1230 (they seem to be the same) and Perflourohexane/FC72/'Flourinert (well, 'the' classical kind)' is that the former is somewhat less inert and apparently slightly toxic to the central nervous system (high doses only), and the latter is sufficiently non-toxic to be used for allowing burn victims to breathe, as it shields their lungs from damage, and is able to provide enough oxygen by dissolving it to prevent suffocation. Rats don't drown in it if submerged and if it is sufficiently aerated to contain enough oxygen. The other difference is that Novec has a Halon-style effect on fire, whereas Flourinert is at least not sold with that intention. Also FC72 decomposes slowly into a toxic, but afaik not dangerous to the elctonics, product, which has to be scrubbed.

Both of those have a vastly higher global warming effect than 'just' using Pentane, but that is rather flammable so one would probably want to ensure the oxygen concentration in the room is too low to result in a flammable mixture. This would probably mean that a human couldn't breath without external oxygen supply, but that should not be more expensive if it is a suitably low-physical-maintenance location, i.e. the systems are installed once and at most swapped out when obsolete or in case of component failure. A human could probably make due with an oxygen tube in his nose and some way to prevent the exhaled oxygen from sticking around in the (probably low-airflow) room.

The cost for FC72 is about 300$/kg, keep in mind the density is about 2.3 times that of water. Novec should be somewhat below, I think (otherwise there is little reason to offer it).

abritinthebay 251 days ago [-]
The latter is the stuff they used in The Abyss, right?
namibj 253 days ago [-]
The difference is that mineral oil cools by convection and my solution cools by nucleate boiling. With my solution, and a flow or iirc about 20m/s, you could cool a delidded AMD EPYC 32 core at 600W. I.e. you are not limited by cooling, you are limited by how much current the LGA pins can handle before they loose stiffness (due to resistive heating in the pin and at the contact area) and then spiral out of control due to the weak contact pressure increasing resistance and leading to the ping disconnecting. This easily goes over to the others, there are documents from iirc Intel about how this happens/works, and how to prevent it.

I considered soldering the LGA pins to the CPU, but due to the craziness of this idea I haven't researched it further.

The thing is, that a dual-socket 32 core/socket EPYC clocked/overvolted for full stability and an overvolting-induced lifespan of 5 years, which does not have problems with power delivery on the way between the interposer (the thing the dies are mounted to and that connects them to each other and provides LGA pads) and the wall socket, would probably be the most affordable (TCO, i.e. including electricity and maintenance) system for non-distributed compiling of reasonably parallelizable software. It would be 'the' ultimate workstation in the sub-$15k range, this would be the full system including the single-quantity amount of, in this case, Flourinert (which is not toxic; there was even research to fill the lungs with it for high-G environments, as it prevents lung collapse. There were issues circulating the liquid fast enough due to the much higher viscosity compared to air, so they dropped it.) and a custom-manufactured (from a local metal shop) containment case for the system and work from a plumber to provide suitable piping. The only non-included thing is the manufacturing and mounting of the nozzle that provides the required flow rate across the CPU to keep up with the heat.

Short answer: mineral oil does not provide suitable cooling for high-TDP processors.

tetha 254 days ago [-]
Hm, this reminds me of two interesting tidbits.

One is the good old P1 125Mhz router we had like 10 - 15 years ago. The only active cooling in that system was in the PSU and that thing throttled it's fan off during normal operation. It had zero moving parts outside of the PSU. You couldn't even get fans for those CPUs. These old systems were fun :)

And beyond that, this makes me think of the computer requirements of coal mines, and I think mining in general. In a mine, a piece of compute has a defined maximum energy emission per square inch surface. If you exceed that, you risk coal dust explosions, which are rather inconvenient, loud and adverse to throughput. The stuff in the article is very similar to industrial computers in such a setup. Quite interesting.

A higher wattage than 400W is utterly pointless for a fanless PSU; if you need to dissipate constant loads of >400W of heat, you will need a fan somewhere (exotic options like mineral oil cooling aside).
vertexFarm 254 days ago [-]
Well you can always add absurd amounts of surface area and mass to the heat sinks to take advantage of thermal inertia, or possibly change components to simply raise your safe operating temperatures to absurd levels. But that's pretty involved. Spacecraft take care of huge temperatures with no fans or even conductive or convective cooling. But that requires enormous, sail-sized surfaces to take advantage of extremely slow radiative cooling.

It would be an exotic option for sure. And not something you'll find pre-built.

Wow. That thing has more surface area than a motorcycle engine. I guess it really needs it with such a relatively low temperature gradient, not to mention the absence of airflow from movement. I'd love to see how that really performs.

8xde0wcNwpslOw 254 days ago [-]
I considered a fanless PSU when I bought my current set-up, but at least back then I didn't find them cost-effective: for a cheaper price I could buy a higher-rated, at least as efficient model from the same manufacturer, and even though it has a fan, it is equally not making any noise in most use cases because it's not running. (I've never bothered to find out when it turns on; later on I added an external GPU to my case, and when its fans start -- not in desktop use -- you can't hear the PSU fan anyway, although I certainly wouldn't mind it running when the case temperature goes up, which it certainly does in certain use.)

Speaking of silent computing; unfortunately my monitor is "louder" than my PC in desktop use for most brightness levels. Anyway, personally I've given up the goal of doing a solid-state PC; a single fan chosen correctly in a case is virtually silent and makes the cooling design much easier; in my experience most PSUs and GPUs produce similar amounts of noise even without fans (and with bad luck, they can be worse).

I think a good route would be to get as efficient a fan-cooled psu you could find and modify it yourself. You can always take the PCBs out of the case and add bigger heat sinks, change the TIM under those heat sinks, add water blocks if needed, desolder components and swap with higher wattage components, etc.

Or you could just submerge the whole machine in mineral oil. That technique really sucks, though. As cool as it is to have a fully submerged computer, it's hell to clean literal liquid laxative out of a PCIe slot when it's time to upgrade the graphics card.

Other than standard ATX/SFX PSU, in the small form factor (sff) scene I've seen using DC/DC PSU like the HD-Plex or PicoPSU and a beefed up external power brick.

The most bizarre thing I've seen, when the power requirement for a single brick wasn't enough, they used two power bricks, for example the Zotac Zbox EN1080 mini PC.

Nice article. About two years ago I wanted to make my pc completely silent as well. It turned out that the cheapest solution for me was to put the pc in another room that I don't sit in and put long hdmi + USB cables through the wall. I also soldered on a longer cable with a power button so I can start the pc from my room. The only downside for me is that I had to run cables along my walls through a conduit but I think in total I paid less than 40€.

Anything that can be used can be misused, if you wanna get into the philosophy of it. And any information that is intelligible to one party can be made intelligible to another party, pending whether quantum weirdness™ pans out or not. Even if entanglement becomes a consumer-level thing, I bet eavesdropping techniques will eventually be developed, even if they only operate on the conventional side of the quantum computer.

But this is more about security engineering philosophy. The Intel management engine relies on a lot of security-by-obscurity, which is not the best way. But I think that Intel chips are passably secure as long as you watch what you're doing.

You can fanless video cards of the same spec as in the article (1050ti) e.g at

TwoNineA 254 days ago [-]
For these cards the giant heatsink is connected to the VRMs so cooling is a non issue. In OP's pictures, he seems to have replaced the heatsink of his card with one from the case without cooling the VRMs.

From personal experience, I tried to silent cool an RX 550 (50 watt vs 75 watt of 1050 ti) without VRM heatsink and the VRM temnperatures were up to 100-103C during a torture test. Adding a fan lowered the temperatures by 20C.

Ratiofarmings 253 days ago [-]
Both the hi-side and lo-side mosfets (they might be 2in1 on a card like this) are rated for their amperage at 125c and are typically capable of dissipating that through their contact with the pcb. Airflow is nice, but not required. Neither is direct contact with a heatsink. Those are for higher end cards (who also rate their mosfets at 125c for good reasons. Max tCase for mosfets is usually 150c. Beyond that they just die.
onli 254 days ago [-]
If I remember correctly that card still needs some air flow to work, normally provided from case fans. That would be problematic in a completely fanless system. A Ryzen APU might be better, as the case would cool it.
tp69 253 days ago [-]
The design of the DB4 is such that the graphics card is mounted vertically. Fresh, cool air flows in through the grille at the bottom, over the VRM area, then up and out the top of the case.

I have more small heat sinks I could put on the mosfets, but they are relatively low profile so I'm not sure they would improve things much.

A single, large heat sink, with long fins (that would protrude above and beyond the nearby capacitors) would seem to make more sense — but given there are no mounting points I could use to clamp it down I'd be a bit concerned about the long-term effect of torque.

Opinions and suggestions are welcome.

Quick note for everyone who might want to build a mostly-quiet home theatre PC. There are several versions of the geforce1030 that use passive cooling/no fans. With H265 acceleration in the GPU drivers, more than fast enough for 2160p, 60fps movies in VLC. They're right around $85.

Same basic chip architecture as the much more expensive 1070/1080. Not something you'd want to run newer 3D games on, but perfect for media center use.

There are several passively cooled geforce1050 (not ti), but you really don't need it for any form of 4k video. My output setup is to a 70" 60Hz TV over HDMI 2.0, with a ryzen 1500X that is slightly overclocked, this setup handled 2160p60 H265 up to around 300 Mbps, at which point it CPU bottlenecks. Which is a vastly greater bitrate than any bluray or torrented 4K content.

If you wanted a setup slightly more capable of 3D games then the 1050 would definitely be a consideration.

Stupid question from a non-hardware guy. If you wanted a completely silent computer, could you build one in a vacuum chamber and just suck all the air out?
ratboy666 254 days ago [-]
No. A vacuum doesn't transmit heat at all. The chips will get very hot. Liquids (generally) transfer heat better that air. You can completely immerse your computer in 3M Fluorinert. That will transfer the heat. Then, cooling fins to transfer the heat into the environment.
natosaichek 254 days ago [-]
The challenge is removing heat. Putting things in a vacuum chamber doesn't make them colder - vacuum is actually a pretty good insulator, so you'd need some mechanism to get the heat out of there with9out using air. If you go the other direction, some people have built computers they submerge in mineral oil or other similar media. That works pretty well for removing heat from components more effectively than air convection.

Yep, you can't always wait for the perfect product to come along — sometimes circumstances force your hand.

Silent Pcs are hard, however the simplest way to make your PC silent is to put it elsewhere....

I worked at a VFX company, where we did interactive client sessions (think: zoom! enhance!) which required a totally silent setup. In somecases that meant trying to silence an entire rack of disks (baselite 8, big glowing thing at the bottom of the page)

Obviously this is impossible, so we used DVI senders ( they are HDMI nowadays) and remote USB

Congratulations tp69! The article details how miners made it difficult to procure components for the build, but the irony is that the miners might be specifically interested in this build for its power efficiency.

A decade ago, I was obsessed with fans and at one point I had more than 10 in my workstation. The noise it created kind of resonated with me, like I would be able to tell when the job was CPU intensive, HDD or GPU; I guess it felt more lively!

But after the smartphone boom, I got more adhered to power efficient, noise less systems (Smartphone/Tablet/SBC's/Chromebook) & after the meltdown spectre (pun intended) my adherence got reinforced.

Anyone looking for low-cost completely silent yet portable system in laptop form-factor can take a look at Chromebooks, now that Google has announced Linux apps support it's usefulness would tend to grow.

I wanted complete silence too, but realized it's way easier to just move the PC elsewhere. I moved it into an adjacent room, made a small hole in the wall for cables (10M hdmi+usb+audio) and that was it, it worked perfectly. The price was trivial - about $40 total for cables. I already had a usb extension hub.

Sadly, that's only useful for 60Hz, as high refresh rates require a short displayport cable to work. For this reason I no longer use this solution.

If you're ok with 60Hz and have compatible room layout I recommend this. The biggest advantage is that it's completely PC agnostic, which makes upgrades way easier, as standard cooling solutions are fine.

Ratiofarmings is on the right track. The noise coming from the computer drowns out the subtle sounds of life all around me.

Someone suggested in the comments that I should just wear earplugs instead. This was my response to him: "But the rest of the world doesn’t make annoying noises that I want to block out — only the computer does. I still want to hear the birds tweeting in the trees and the wind blowing past the awnings and the rain hitting the roof and the ice-cream truck driving by and my wife chuckling at something she’s watching and the cats running along the floor and the microwave oven heating a meal and the kettle finishing its boil. I’m not trying to disconnect from the rest of the world — I’m trying to reconnect to it."

A lot of the most interesting and enjoyable sounds in life are very, very faint. It doesn't take much noise to drown them out. Even a single fan will do it. Now I can hear those noises and get 'work' done at the same time. It's really hard to describe, but 'magical' comes close.

This is a wonderful project. It looks very sharp and has pretty good components.

But yeah I should probably fix that...

Possibly caused by the piezoelectric effect on an SMD ceramic capacitor, making it vibrate and hit the PCB surface at an audible frequency.

I use the thing as a media center (xbmc/kodi), and it's quite nice to have a fanless/zero noise setup for this usage.

I have exactly the same, and I'm very pleased with it. I use it as my main home computer, which includes occasional use when I'm working from home.

It overheated once (Linux/Ubuntu suspended automatically), my room was also 28°C or something and I'd been encoding videos non-stop for hours.

Interesting project. I was playing with the idea of running Linux on one of those little Chinese Qotom PCs without fan for a server, but I live in Portugal where it can get very hot in the summer and decided that the potential fire hazard is not worth it.

Overclocking, fanless PC, etc. are all fine if you can make sure that there is no problem if the ambient temperature raises to 40 C - or even higher, if the machine is accidentally exposed to sunlight. I don't trust most existing fanless solutions to work reliably under such conditions.

If you're removing the GPU heatsink and fans, buying a dual-fan card isn't necessarily a dealbreaker depending on the design. For example, this 1050Ti from EVGA has two fans but the board itself is pretty small.

Real late to this thread, but for the last ~10 years I've run my desktop in the adjacent room's closet. My desk has the monitors, speakers, USB hub for peripherals, with cables running through the wall to the actual tower/UPS/etc. It's a great setup if your living space can accommodate it (the adjacent room is my bedroom, but I shut this computer down at night).

I started doing this because quiet computers just weren't available at decent horsepower. Rad to see a build like this!

I was wondering about these cases where the metal outside is directly connected to the CPU. Would this make it possible to kill your machine by touching it with a static charge?
baseethrowaway 253 days ago [-]
The CPU's heatspreader is not connected to any leads on the CPU. The case should be grounded through the power supply, therefore, it should be like touching ground with static charge.
floatingatoll 254 days ago [-]
Apple’s iMac is an excellent budget alternative to this approach, as long as fan noise under high load is acceptable. 99% of my usage is not under high load, so it works out to be silent effectively any time I’m not wearing headphones. Using the CPU and/or GPU and/or writing gigabytes to the SSD will wind up the fans, so this is not even remotely “always silent for power users” – but it’s always silent for general non-coder usage!

I won a silent computer 5+ years ago as a prize at a lan party. SSD drives, two of the best passively coolable gpu at the time (ATI I Believe?), passive CPU cooler, and the whole case was lined with musicians sound absorbing foam. I think it did have an optional 240mm fan but I never heard it even when I turned it on. It was so nice that I have built my newest computer in the same way (though I did put some big storage drives in it).

I did a similar (but much more ugly) project a few years ago, and found that the result was that one could then hear various electrical crackling sounds from inductors transformers and capacitors, especially from the power supply and motherboard.

I've been interested in passively cooled PCs for a while now. Particularly, I've been considering building a computer which outputs its heat into a wall using heatpipes and a metal plate heat spreader. Although I can't find any case of this being done by anyone else, so I'm not sure if it's a crazy idea or not.

Since he described how his cpu cooling is capable of dissipating up to 105W and he uses a 65W cpu, he can overclock a little. He is also using fast memory and a 1050ti is quite capable of running pubg well. Based on that pubg should run well.

Samsung Evo drives have a built in hardware error, where the read speeds diminish with age.

The firmware hides the read-speed decrease, or prolongs the detection of it, by shuffling data around in the background.

My first silent system was about 17 years ago that booted Linux from a floppy drive into RAM.

This was before solid state storage options were affordable.

It was a Pentium 1 (can't remember the model) and I had disconnected the PSU fan. Ran for a long time and I used it mostly as a router.

tp69 253 days ago [-]
Nope, rubber dome.

I'm actually on the lookout for a wired, backlit, white/aluminium, chiclet, TKL keyboard. Basically something like the Apple Keyboard but sans NumKeypad, backlit and keyed for Linux/PC. Bonus points if it has a column of macro keys on the left.

If anyone knows of one please drop me a line.

zemo 246 days ago [-]
didn't notice this comment until now.

This is a somewhat deep rabbit hole, but what I will tell you is that you'll probably have a hard time finding what you want in a chiclet keyboard because there's not much of a market for chiclet keyboards among keyboard enthusiasts. Chiclet is both a switching mechanism and a keycap; most of the keyboard-enthusiast community is working with setups that involve separate switches and keycaps that are interchangeable.

What you probably want in practice is the following characteristics: a specific key layout, all of the keys should be the same height, the key travel should be low (i.e., the amount of distance you have to depress the keys before registering a keystroke). No idea if you want the keys to make noise or not, or how stiff you want the springs to be, but that's customizable too. If you want chiclet keys because you want low key travel, you have a lot of options. If you want something really thin, there are way, way fewer options.

A single left column of macro keys is not something I've ever seen, but the one keyboard I can think off of hand that has a similar layout is the Red Scarf II, which has two columns of macro keys on the left side; unfortunately it's not currently in production. Some people use an external num pad and put the num pad on the left for this purpose.

I personally use a KBD75, which is an aluminum body, tenkeyless layout with a right-hand column, and it's all programmable with QMK so you can make any key do whatever you want. For example, I have a key that, when I press it, reverses the position of the Alt and Win keys, so that I can switch between layouts for either PC or Mac and have the Alt, Command, and Windows keys always in their correct location. Images and build information here:

you can get keycaps that have a flat profile that are interchangeable with any MX-Compatible switch. DSA Granite is a super popular flat-profile keyset like that:

it's pretty common to add rubber o-rings to the keys to reduce the travel. But chiclet keys are generally going to restrict the rest of your options.

Anyway has a bunch of info on all this stuff.

tp69 244 days ago [-]
Agreed, it's a very deep rabbit hole. The 12" PowerBook G4 that I bought back in 2004 had the best keyboard I've ever used — I still have it and occasionally use it. But I've been trying to hunt down a desktop equivalent ever since (but with backlighting and TKL ANSI layout). Haven't succeeded so far. Still trying though.

Although my highest priority (by far) is low noise, I do prefer short travel/registration and a soft landing as well.

Prompted by your post, I did some more research and decided to upgrade(?) my gaming keyboard to a Logitech G Pro TKL I haven't tried Romer-G switches so it will be interesting to see how they turn out.

Meanwhile, now that Corsair's exclusive rights to the Cherry MX Silent (Red) have expired, I'm hoping to see a lot more keyboards with that switch make their way into the market. The Corsair Strafe RGB was tempting, but the light spill from under the caps was far too gaudy and distracting for my liking.

Cherry MX Silent (Red) switches with landing pads and o-rings seems like a combination that would work well (for me) for gaming.

For the DB4 and daily driver usage, though, the hunt goes on. I'll keep using the wired Apple Keyboard until someone else comes up with a TKL clone.

nottorp 254 days ago [-]
That would be me. I don't have a fully passive set up (I don't really trust those, since I tend to use both the CPU and GPU a lot) but it's silentpcreview silent.

To make up for it, I'm using a mechanical Razer Blackwidow. It's so loud you can get distracted by the sound of your own typing :)

There are several. But the liquid will heat up and eventually require cooling again. Pumping it somewhere generates noise. Evaporating it creates costs and need to frequent maintenance. And a large enough tank for that not to be an issue is impractical.

Sometimes I can "hear" my processor working through my headphones. I'm not sure how, but, for example, when I scroll down a page I can hear high frequency chirping in my headphones which stops as soon as I stop scrolling.
woliveirajr 254 days ago [-]
It is caused by the increase/decrease in power consuption, as in general the audio chip isn't properly isolated from the power source of your computer. So, as more power is used (by slightly increasing the CPU speed, for example, to render the page as you scrooled it), the audio chip amplifies it.

It is a problem of some motherboards, and one way to get ride of it is to use another audio chip (for example, a small USB device that acts like a sound card).

fipple 254 days ago [-]
The external USB sound card doesn’t always work because the USB supply voltage can vary with processor CPU. You need to use a USB headphone output with good isolation.
stan_rogers 254 days ago [-]
...which is still a "USB sound card", no matter how you choose to look at it. It still needs to be a combined DAC and headphone amplifier in addition to being a set of 'phones.

Personally, I use an Audioquest Dragonfly USB DAC/headphone amp, which gives me the option to use either headphones (of my choosing) or speakers. (And unlike a larger "breakout box" USB sound card, it's quite portable, being about the same size and shape as USB thumb drives used to be.) It's a good fit for me, but if you need mic input, there are other devices - or you can still use the mic in of your regular sound card/integrated audio.

21 254 days ago [-]
I can also "hear" something when I scroll on some computers, but I hear them with my ears, no headphones required.

On one particular susceptible computer I did a bit of testing, and scrolling white background pages made the noise, but black background ones didn't! Scrolling a completely white page also made the noise. And it depended on app, some apps were immune, it seemed to only happen on GPU-accelerated apps, like browsers.

jandrese 254 days ago [-]
I used to be able to hear data going over the serial port back in the modem days. Some systems used to make a buzz when scrolling too. These days I have not heard that, but I'm not sure if it's because the frequencies have gone up (outside of my hearing range) or the parts have better isolation or I'm just going deaf as I get old.

I don't think I've heard scrolling noise since I stopped using analog video signals.

Back when I was making electronic music, I noticed that I could hear pixels. When I did things that changed a region of the screen — pulling down a menu, switching windows, etc. — an audible whine would change on my audio monitors.

sliken 254 days ago [-]
I do find that generally USB headphones do better and minimizing interference/noise. Which makes sense, having a sound card on your motherboard is pretty much a worst case scenario. With USB it's not till outside the case that you are susceptible to RF.

High pitched electric buzzing or hard disk screeching seem to be worse than fan noise nowadays with all the great coolers available.

That being said, within a year of using Windows 10 four (!) of my hard drives have begun making loud screeching sounds. They're technically fine, but still unusable.

ovao 254 days ago [-]
I built a fanless (technically had fans, but only turned on if needed), semi-high-performance open bench-style system several years ago.

It's really pretty nice in theory. The reality is that some components still emit a good bit of noise, and unlike fans, the noise they tend to emit isn't very pleasant. Power-hungry graphics cards are by far some of the worst offenders; without being masked by fan noise, they can be incredibly loud and irritating. An open bench PC is definitely cool, but was kind of a mistake in my case.

Fan tech has improved to the point that I think, more often than not, you really want to have them. Otherwise it's time spent trying to eliminate other noise sources that would otherwise be conveniently and usually pleasantly masked by a little wooshing.

Completely agreed. When GPUs do this, I just declare them defective and send them back. It comes down to a lack of quality of the electrical components and simply shouldn't be a problem, especially with the current GPU prices.
