My power supply has been making a whining sound lately. It goes away while scrolling and during 3D graphics.

I know it sounds odd, but ive read that other people have the same problems, but they neglected to mention what the cause was.

I'm running a Corsair 450W PSU, it's a really nice power supply with plenty of power for my setup.

I fix computers for a living and this threw me off. I don't want to take the PS apart being that it will void my warranty.


Anybody got any ideas?

IT IS NOT THE FAN. if it was the fan then I would have already replaced it.


oh yea, turned the blowdryer on in the other room and the whining stopped.
