I need help with my set up, here are the specs
Lian li odynamic
Arctic freezer 360 mounted on top as exhaust
3 sl120 mounted on the side as intake
3 sl120 mounted at the bottom as intake
12700k
3080 ti FE
8x4 ballistix 3600 cl 16
Z690 edge wifi
850 rmx

So I use msi burner to undervolt my GPU it runs stable at 885MV at 1905. I set the fans curve manually with zero rpm override (fan should be at zero when GPU is below 40c) but it doesn’t get activated so it’s stuck at 1000RPM all day which is 30%

Then I use fancontrol and set my pump fan curve and my sl120 since they’re all connected to one lian li hub I can’t see the rpm but they use the same fan curve.

I experience strong vibrations and hum from the fans when gaming to keep the temps low. The sl120 are very loud at full speed and are the ones causing the problems. So I’m wondering if it’s because the liquid freezer and the sl120 have max rpms that cause these issues and how I can resolve this
 
Fans produce noise at high rpm and the only real solution is to lower the max rpm. However this will obviously then allow temps to rise so it has to be a compromise. If you want your system to be quieter then you must accept that it will be hotter. CPU and GPU only start to throttle at the specified temperature so if your maximums are 1C less than the threshold then you'll still get maximum performance.

Properly mounted and good quality fans should not cause vibration themselves although the airflow could - check whatever case grill/mesh/filter arrangement the case has.

There are a few things you can try:-
1. Play with the fan curves in BIOS/Motherboard Software/MSI Afterburner to see if you just happen to be hitting a fan speed that creates resonance - so if the fan speed is slightly increased it gets much quieter. From memory the Arctic fans can have a resonance around 1000rpm
2. Check your mounting to your case. Sometimes the case itself can make vibrations much, much louder if it's thin metal. If this is the case (punny) look at options for soft mounting.
3. Go full custom water loop with top of the range fans. The pursuit of silence never ends :D (sorry - but you did post in the Watercooling sub forum, so what do you expect :cry:)
 
So after un mounting the fans and testing them out of the case it seems like that’s just the way they work at high RPM so I had to decide to either work with them or sell them and get something less noisy. I stuck with them but used fancontrol to mitigate the issue by having the bottom intake fans dependent on the GPU temps will the side ones use CPU temps along with my AIO. This way is a nice balance still a bit noisy compared to my AIo running at 2k RPM and being very silent but I guess turbulence is created inside the case which creates some weird noise. So far so good

Strangly enough the slight hum from the arctic fans on the AIO don’t bother me as much as the sound resulting from the 6 uni fans running at above 1300 RPM at the same time
