I just built a new pc and i have an r5 1600 with the stock cooler. originally there was no problem but when i adjusted the fan speed it started making a high pitched ringing noise. the noise only stops when im at 100% fan speed or under 20%. i've looked for any loose cables and there dosen't seem to be any. any idea what the cause could be?
ok i tried the paper. its defenitly not the power supply but im not sure if its the cpu cooler now. it seems to be coming from somewhere around the cpu. could it possible be the vrms or something else on the motherboard?
fans often whine at certain rpms, that's just due to the fact that they have moving parts that create vibrations which under certain circumstances can become a audible whining sound. Create a fan curve to work around that rpm or just get a better cooler.
