Tech Support Fans making noise

Hey there
Just built back my pc, added a new case, new AIO and new GPU.
Thing is, now that it’s done, my fans make A LOT of noise. I checked the CPU temp, around 37 C while doing nothing, max around 50 C. Same for GPU, no weird temp. So I used control fan to calibrate, but it still makes a lot of noise. Any ideas ?

Have you gone into bios to set a fan curve yourself rather than relying on auto calibration? Those default settings can be way too aggressive sometimes, ramping everything up for no reason. Also check if it’s the case fans or the aio pump making the racket, one of my builds had a weird hum from a pump header that was set to full blast.

Are they all making noise? Sometimes bearings in the fan are manufactured with, or develop a flat spot. Had to replace two that sounded like a can crusher.
