the real issues is the psi has 0 or 100%, nothing in between.
I understand that intake is recommended in the guide but I wonder if running it as exhaust makes any difference? If I were testing this I’d not set a min for the CPU fan … initially anyway.
From the holes in the side panel against which the fan shroud presses. Noctua have designed an alternate, too.
I have yet to hear any PSU fan on mine…I just leave the APU fan on constant 25% duty as an NFA12x25 is below ambient noise at that throttle
So i also have the annoying psu noise. What fixed it for me is go into the BIOS and set the cpu fan on always on and set minimum temp at 30 degrees celcius. The noctua fan is almost silent and now the psu does not overheat and the psu fan does not activate. TBF that is unacceptable! You can not advertise a pc as silent and then shipping it in such state.

In my case the CPU fan (RGB one) is an intake and without a front fan there’s a lot of hot air that tries to escape through the tiles. If we increase the pressure inside the case by adding an intake on the front too, is it not going to increase the noise even more?
I contacted customer support, as expected from reading other stories here they came back with a generic answer asking me all sorts of things as if they didn’t know about the problem. You can’t make that up:
Could you confirm if all other functionalities of the desktop are working as expected? This includes the webcam, microphone, speakers, keyboard keys, display, fingerprint reader, etc., aside from the PSU fan issue.
I might not have been clear enough .. sorry if that was the case.
I’d set the top front case fan to exhaust and the CPU fan to intake

Another user here with the same problem. Just to let you know that after following the same steps as other users (contacting support, sending a video with the noise, proceeding with the shipment of a new PSU, and installation), I still have the noise I had with the previous PSU.
I was very clear in my previous emails that I did not want to waste time changing components without a clear solution, but it seems that they have ignored me and sent me another PSU exactly the same as the original.
I hope this helps other users with the same problem, that changing the PSU is useless unless they make a V2.
I’m running into the same issue many others have reported. I’ve tried most of the solutions suggested here (thanks @AttilaBerencsi), but they only delay when the fan ramps up, and the PSU fan is still very noisy overall. This isn’t just a typical fan noise either, it’s extremely loud and has a noticeable scratching component, which makes it sound unhealthy and potentially defective.
Even with the main APU fan locked at 25%, and elevated platform and an additional rear fan also fixed at 25%, any sustained heavy workload causes the PSU fan to spin up.
I’m going to contact support, but as JoRo already mentioned, I’m concerned this will just result in another PSU with the same problem rather than a real fix.

TBH, that sounds like a different issue (a defective fan). The fan is always going to spin up under heavy load.
The main issue discussed here is that the fan runs when idle.
In that case, yes: setting the main APU fan and adding an external fan helped prevent the PSU from spinning up while idling. I remember being very surprised when the first time the fan kicked in while the computer was doing nothing, especially considering how noisy the fan was.
Anyway, for the scratchy fan, I contacted support.
Recently received my FW desktop, batch 16 – have the same issue with PSU fan noise kicking in every few minutes when system is idle.
The problem is that the PSU fan acoustics are extremely unpleasant - I don’t think I can tolerate it sitting on my desk next to me.
Having the main CPU fan (noctua) running constantly seems to help a bit, but doesn’t seem a good permanent solution.
Has anyone tried using “FlexGURU Power Supply, Flex ATX 300W” with the Framework case?
Framework, is there any progress/updates on resolving this issue?

I am wondering the same. While an intake CPU fan, is cooling the CPU more effectively, if the aim is to bring case temperatures down, to reduce heat at the PSU, turning it around and configuer the CPU fan as an exhaust fan, should make a difference, especially with the original shroud. The hot air should then be directly exhausted. and cool air pulled in through other opennings. I can’t test that so maybe someone can have a look at that (unless that has been already tried and I have missed that post).
That’s all you’ll get from Framework currently (besides opening a support ticket to make them aware that you are affected too):
Update on my journey to reduce PSU fan noise.
Have not done too many physical tweaks. PSU fan still turns on but intervals in between are quite long and it seems to run for shorter.
I’m running Ubuntu 25.10 with the Noctua APU fan from Framework and this is what I’ve done:
- installed CoreFreq which helps a bit with idle power consumption (from 12 W down to around 9W)… needs to be re-built with each kernel update which is a bit of a hassle as I’m usually not building kernel modules
- built a podestal out of wood (pictures somewhere further up in this thread) so that the bottom plate has a higher distance to the wooden table it is standing on
- set APU fan at 25% min
- installed the Noctua 80mm fan following the official install guide which was shared here not long ago and set it to 25% min (source set to mainboard power)
The 80mm fan did not make that huge of a difference. Maybe I’ll keep tweaking settings and I think someone suggested to turn it around?
I think the podestal makes a noticable difference as the bottom plate where the PSU is really gets warm. APU fan set at 35% made a huge difference - PSU fan almost never turned on during a work day with my regular work load (mostly browsing, watching videos, light dev work & ssh sessions). Currently running at 25% as 35% is far more noticable to the ear. Not loud by any means, but a constant very silent noise of air being transported which I can hear clearly because the Desktop sits right in front of me on the table. Will experiment with 30% and ultimately switch back to 35% as it’s still better than the PSU fan. At 25% it just still runs too often.
A bit disappointed of the additional 80mm fan. The fan is great, but it does not make really a difference when installed like the official guide suggests. At least for me in my environment.
Hope we get an update from Framework and that there is a solution. Don’t mind swapping the PSU again (got a replacement which did nothing)… if it means the fan only turns on with high loads - maybe even with a gradual ramp-up instead of 0 - 100 in an instant.
Screenshots of temp sensors right now (PSU fan is running - kicked in a few seconds before I took the screenshot):
Edit: After writing the post I let the system running at APU fan 30% for some time - seems to be the sweet spot. Only time will tell if the PSU fan ever kicks on during a longer work day
For anybody testing - don’t be discouraged by high temperatures immediately after turning the pc on. Temps were through the roof for the initial half hour or so (some sensors between 40 and 60 °C) - maybe because I spent some time in the Bios and I assume fan control is not very sophisticated when in the Bios which led to increased heat?
I think the room itself has cooled down as well (sun went down) which might have helped decrease by one or two °C. I’m in central Europe and weather is cold-ish. Not looking forward to hot summers. Hopeful that there is a real solution available till then.

Has anyone gotten a replacement psu and have that actually fix the problem?
Several people (me included). All are the same.
They (Framework) won’t share details yet, but they are working on it.
Does anyone have fan SPEED feedback available under Windows 11 Pro? – I mean of the System fan, I know it is impossible to get it from the PSU w/o a USB / CorsairLink like connection? I get no speed sensors under HWiNFO, HWMonitor or LibreHardwareMonitorLib used and provided by Fan Control.
So I purchased a Corsair Commander Duo to control my two fans.
Yes to temp sensor info from HWiNFO
No to being able to control the fan via Fan Control but I can get fan data using

Oh Geez. What is wrong with my brain?! I meant to say I don’t get fan SPEED data by those three methods. I DO get temp sensor data in HWiNFO and HWMonitor. I’m going to edit my post to correct my mistake.
Ok, so I’m not alone. What is the program that gives you the fan speed in that black screencap? Thanx.
