I recently noticed this high pitched whining sound coming from my P.C.
it happens at random times, often when idle
I believe the sound is coming from the mobo/cpu area
how can i stop this?
the motherboard is asrock z77 extreme 4
do i need to return it? Ive had it for around a month

probably a fan of some kind. I noticed with my old 4870 that its fan would whine between 15-60% speed after a year or so of use. stick your ear near and try to isolate the noise.

if you can, disable pwm fan controll in bios and allow them to all spin up to 100% to see if it stops
