    Try to plug in lower intake fan, and unplug the upper one. Remember that the coolest air comes from the bottom. That way your front intake fan cools the whole motherboard and chipset. The goal is to create "Z" shaped airflow. :wink:

    Cheers!

    it would be good if they were multisampled using mic proximity with an expensive binaural microphone head, and of course map the highest velocity to one of the ears against the computer case. I guess I'll want a patch that has a floppy disc that's mining bitcoin or something, and maybe convolve that inside of some kind of bandpassed tin box impulse. maybe i could sequence it using a circklon. can i borrow someone's cirklon?

    First of all, it depends on how many things you have in your computer. Don't use mechanical disks. They make a lot of heat...
    You just need two quiet and big fans in the chassi.

    And secondly, buy a high quality 1000 Watts or so power. This choice makes the fan on the power don't run at all most of the time...

    My DAW is very quiet and I built it with these things in mind. My hardware synths power source sounds more than the computer. :)

    (I do have a gaming gfx card but it doesn't spin up when using any DAW)

    "...intake and exhaust airflow is roughly same, or slighty higher..."
    Not, unless your computer case is a balloon.
    Intake and exhaust volumes are always the same, *except of the moment when you switch your system on or off.

    My Way for a Silent PC:
    - The Akasa fan control controls 4 fans -> 800 UPS (for 5.25” PC bay)
    - 4 x Scythe - Slip Stream Lüfter - 120x120x25mm
    - 2x front, 1x bottom - blowing in / 1 x out - blowing out

    Slip stream 120 mm The Slip Stream fan series is one of the quietest and most powerful on the market. By reducing the
    size of the fan hub, the Slip Stream 120 mm fans achieve 20 to 40% more air flow compared to conventional fans.
    - Lüfterdrehzahl: 500 upm / 800 upm / 1.200 upm / 1.600 upm / 1.900 upm

    Note: During a heat wave in summer you should point a fan at the PC case.

    In my opinion by far the best way to eliminate PC noise is by putting distance between the PC and the user.

    Mine is in a ~4m2 step in storage closet. Downside is dealing with the the cable runs, but with little effort and investment you can make it look ok. If this is an option, I would highly recommend everyone to consider it. 100% quiet experience and you can run your fans as hard as you want.

    So here is the results.

    upload_2021-7-24_10-15-2.png

    Now, I have Threadripper 1950X with Noctua U14S TR4 Dual Fan setup. There are five 140mm fans and three 120mm fans. Here (in the video) everything is running at full RPM. The three 140mm fans were running at 850 RPM, the other two 140mm fans were running at 1500 and 1200 RPM respectively. The 120mm fans were running at I believe 1000 RPM. I was doing a Cinebench R23 test and the CPU temperature was 35°C at 100% load and the PCH was at 51°C and Motherboard was at 40°C. Now the PC was making almost 60dBA Noise. I was able to reduce 20dB using my DIY Box. I hope to reduce it even further.

    Here is the Video
    You will get the proof in the video.
    My room's ambient temperature was 29°C and ambient Noise level was 33.5 dBA.

    I have a Fractal Audio Design6 case and at present moment, with a regular CPU fan (instead of liquid cooling that I would usually opt for) and stock fans, its so silent that you cant even tell its on aside from the screen showing you a picture and your speakers giving you sound. you could literrally put your ear up to the tower and you wont hear a movement of air. My laptop makes more noise. Get good quality fans and throttle them down. Read reviews and dont just buy anything...a small bit of google research and some reading and you'll find the best solution to your problem. Don't know where to begin, try googling silent or near silent computer fans. Good luck!

    Well, for me, all my 140mm fans are from Noctua and all 120mm fans are from Corsair. When buying Fans, I believe my end goal is not to be silent ones but more cooling. I mean I will always choose more cooling over silence because as you can see my DIY design and video, I can reduce 20 dB atm and I will aim to reduce 30dB noise. But, with 29°C ambient temperature My CPU idles at 13°C and goes to 35-40 °C at full load. Fans are way cheaper than my Threadripper CPU and so I usually run all the fans at full speed all the time. I know, this will make the fan lifespan shorter.

    so, I just recently received the new M1 MacMini, and daamn that's what I call silence - its 1700 rpm idling fan is inaudible and with cpu temps around 30-35°C system doesn't heat at all either
    :woot:

    Well, what's the TDP of the cpu?
    For me, it is 240 Watt.
    TDP changes everything, in all honesty.

    probably around 15W :rofl:
    but it does offer basically equal performance to my ~150W i7-5820K :woot:

    native M1 support with Reaper for ARM beta here
    :chilling:
    and native M1 support of Fabfilter, Analog Obsession, Valhalla, Acon Digital, Overloud, Melda and few others (NOT iZotope, Waves, Plugin Alliance, Slate and other subscriptions where devs claim neverending support if you don't stop paying LOL)
