Just today I noticed a sort of droning whine sound emanating from my PC off and on at fairly regular intervals, and now I can't un-notice it. At first I thought it was GPU coil whine, but now I don't think it is. I went into the BIOS and started messing with the fan curves to see if one of the fans was responsible, and when I turned off the CPU fan curve, as the fan spun up to 100% I heard the whine. It's a mid-to-high pitch but not excessively high, and is distinctly separate from the expected white noise generated by the fan. It's a sound that kind of pierces through other sounds but is more in the background than them.
Is it normal for a CPU cooler to make that sound? I recently upgraded from my 5600X's stock cooler to the Thermalright Assassin X120 Refined SE, and while I'm very happy with its cooling ability, I'm not thrilled about the whine. It appears to only happen at higher RPMs, so I adjusted the fan curve and that seems to have reduced its rate of occurrence. Is there anything I could do to make the whine go away at higher RPMs?
