hello i am hearing humming sounds from my pc but ive searched some videos that it says its coil whine, i searched the sound on how to describe it but it sounds different from any other coil whines ( i dont even know if it is coil whine or not) but the thing is i tried benchmarking to see if its the gpu i ran benchmarks and the sound is always random even at idle, sometimes it humms and sometimes it doesnt but 6/10 it humms , i tried using msi after burner to raise the gpu fans but the humming sound is still random, even at playing games, but you can only hear the sound when i close the door of my room and everything is silent, so while other things are running (example air conditioners or other appliances) you dont hear it unless you turn these off and make the environment silent
now how do i stop it or how do i diagnose it, im too scared to follow youtube guides to identify it whether its the powersupply or cpu fan by booting the computer and stopping the fan using a stick

Lots of electronic equipment can have coil whine. Just checking. Most of the time there's nothing to worry about.
