I recently built a new PC and installed an EVGA 500W Power Supply 100-W1-0500-KR
I keep hearing the fan whrrr very quickly and then go back to normal every 5 seconds or so. I go into the bios and it switches between 2000rpm and 650000rpm. No options in the bios to fix this anywhere and can't find any drivers/software to edit. I'm guessing this is very bad for the motor for starters, it is also extremely annoying hearing the speed change every 5 seconds.
Any advice?
