Temperatures of the CPU and GPU I have,

I am not bothered by the fans when I use the computer.
When I don't use the computer and instead read, attempt to
sleep etc the fan sound is annoying enough, I have to
hibernate the computer, but then I loose the Internet
connection. Gnus, ERC and downloads scripts, e.g. this -
https://dataswamp.org/~incal/scripts/tokyo-dl - all resume
their connectivity automatically but after having that
happened 1000+ times it has started to annoy me.
So this is the use case, when I don't use the computer, I'd
like the fans to slow down as much as is safe to do. If this
can't happen dynamically as a function of the load or
temperature I'm happy to issue the commands manually, altho
that would be less safe (human factor, unpredicted events
etc) no doubt.
So if we start over ... forget about everything I said ... how
would go about this?

OK, I did check out the BIOS/UEFI/Setup and all five fans can be configured individually. There are five options. Control can be disabled, auto (the default), DC, or PWM. Wind-up time is set to 0. Minimum speed is 200 RPM. Profiles were Standard (the default), Silent, Turbo, and Manual. I set the three case fans to Silent, let's see what happens ... (Maybe the "auto" control doesn't work, I can try put that explicitely DC for the 3-pins and PWM for the 4-pins.) -- underground experts united https://dataswamp.org/~incal

I spoke to soon, there seems to be only one set of options for the CPU fan, so I guess the CPU_OPT and CPU_FAN are the same in terms of options. Anyway now I've set all 5 to "Silent" but the temperature is the same and to be honest I can't say it is any more silent than before ... is it? -- underground experts united https://dataswamp.org/~incal

You need to collect data. - The computer should be able to tell you temperatures and fan speeds, either via the OS or via Setup. - If you have a microphone, you can use various Linux apps to make sound measurements. - If you have a smart phone, you can install various apps to make sound measurements. Changing settings and making measurements at idle is a starting point. You should also put the machine under load and make measurements. David

Yes, but I know already that even with all fans (2*CPU cooling tower, 3*case) at "Silent" and with the powersave governor it still - if indeed anything changed - it still makes to much noise so I still hibernate the computer when I don't use it. The GPU fan looks so small it can't make a lot of noise one would think, and the fans for the power supply/the HDD are inside a little box even inside the computer case (don't know if it has a name?) but if they are really noisy I guess it could happen? -- underground experts united https://dataswamp.org/~incal

Small fans are problematic: if they need to move quantities of hot air, they can only do this with high rotational speed and thus noise. QuietPC are worth looking at just to see the range of quiet fans. Likewise Overclockers or similar. All best, as ever, Andy Cater

The unaccounted for fan is a Corsair A1225M12S. It's noise is
18.9 db(A).
So now all mounted fans and the HDD are accounted for, it
lands on 37.3 dB if the dB algorithm is correctly understood
and implemented (start with the highest, then add 3 dB every
time it is doubled).
So, that means only the GPU and the PSU are left!
I did Google the GPU (GFX card) but I couldn't find anything,
it is a msi Nvidia Geforce GT 710.
As for the PSU, I must open the computer and have a look since
I didn't write down anything except "Seasonic" ...

In "normal" situation, the speed is kept so it will achieve a good balance between temperature and the speed of the fan. If your computer is not installed in a very warm place and you are not doing some intensive work then it's possible that even running at a low speed the fans still do all the job needed. If you take the option for let say "performance" then it will be at max speed so the system is the coolest possible all the time.

But changing the profile (governor) doesn't produce any (noticable?) sound level change and also the temperature of the CPU and the GPU seem unaffected. Heh, I have an infrared thermometer, is there some other part of the computer I should aim for? ;) No, that command sets the CPU so there is where the change should be noticable, right? -- underground experts united https://dataswamp.org/~incal

Here are various ideas:
- Set the Linux CPU governor to "powersave".
- Use the motherboard Setup utility to under-clock the CPU and/or switch
off cores.
- Do the same for the GPU, if you can.
- Tune the CPU and chassis fans using Setup. Try the "EZ Tuning
Wizards". Try the QFan "Silent" profile. Try making a manual profile
once you understand the options and effects.
- What about GPU fan(s)? Power supply fan(s)? Any other fans?
- What about HDD's? If they are not vibration isolated, the chassis can
act as a sounding board.
- Any other noise sources in or on the computer?
- Dress cables inside the chassis to improve airflow.
- Install sound and vibration absorbing materials inside the chassis
--cork, rubber, foam, etc.. Various manufacturers sell materials and kits.
- Buy a "silent" chassis with doors/ covers over all openings, sound and
vibration absorbing materials on interior surfaces, vibration-isolated
drive cages, etc..
- Install sound absorbing materials on the surfaces around the chassis
-- floor, wall, furniture, ceiling, etc.. Place free-standing sound
absorbing baffles around and/or over the chassis. Put the chassis
inside a cabinet lined with sound-absorbing materials and a ventilation
fan. Carpet scraps can be an inexpensive sound-absorbing material.
- Move whatever service(s) you need running 24x7 to a VPS.
- STFW for "silent PC" to get more ideas.

If nothing else helps to find the culprit, then consider to unplug all case fans to prove that it's not them. A bit more adventurous is to run the CPU without fan for a few seconds. (I assume from your fan list that it is a larger box where such manipulations are feasible.) Have a nice day :) Thomas

Hi, Emanuel Berg photographed: > https://dataswamp.org/~incal/ebchw/fan-top.jpg The case fans look like they would produce a lot of wind if really running at full speed. Whatever, i'd make a closer photo, unplug them, listen how much noise is missing, and then plug them in again guided by the photo. That perforated metal plate at the bottom looks suspicious. Power supply and hard disk cage, if i remember correctly ? How is the noise if you unplug the power of the whole mainboard ? Have a nice day :) Thomas

The unperforated portions of the top surface could be covered with sound absorbing material. Conspicuously absent are drive cages; but I do see drive case mounting screw holes. If drives are not needed, the mounting surface could be covered with sound absorbing material. The front cover over the fans will help contain noise; especially if it is lined with sound absorbing material. The unused expansion slot filler plates could be covered with sound absorbing material. The underside of the chassis top could be covered with sound absorbing material. The inside of the chassis covers (left side and right side) could be covered with sound absorbing material. Sound absorbing material could be placed outside and to the rear of the chassis. David

The chassis left side is a windowed side panel. Covering that with sound absorbing material could be done, but would block the view. David

What material would that be?
And, won't it prevent the airflow and/or prevent heat from
exiting the case?

The HDD is below with the PSU, I think.
I got an idea, aren't the noise specified by the manufacturer?
Here it says "Low-noise operation of up to 14.9dB(A)",
that's for the Shadow Wings 2 140mm PWM.
<https://www.bequiet.com/en/casefans/1701>
The CPU fans are "Low-noise operation of up to 15.9dB(A)", the
Shadow Wings 2 120mm PWM.
<https://www.bequiet.com/en/casefans/1626>
And the non-PWM Shadow Wings 2 140mm is
"Low-noise operation of up to 14.7dB(A)"
<https://www.bequiet.com/en/casefans/1699>
So that's 4/5 fans accounted for, I have to restart the
computer to see exactly what fan the remaining is. Anyway
db(A): 14.9, 15.9 (2), 14.7
How is it with db(A), if you have x db(A) from one thing, and
you have two of these, does that mean you perceive that as
2x db(A)?

So, the two loudest fans are around 19 dB. The HDD is 2.9 Bel = 29 dB. Beyond the fan acoustic noise, there is HDD vibration. If you mount a HDD directly to a piece of sheet metal, the sheet metal will act like a sounding board and convert the HDD vibrations into sound. My Antec Sonata chassis has silicon grommets and shoulder screws for mounting each HDD into its sled. This design effectively decouples HDD vibrations from the rest of the case. If you could implement the same idea for your HDD or for the drive cage, that would be good. Alternatively, you could put vibration dampers between bolted connections and/or damp the chassis vibrations. Applying sound absorbing pads to the inside of the case should address both sound and vibration. David
