Weird noise coming from CPU area when playing certain games

I've been having this for a month now and I'm starting to get a bit worried. My CPU makes a strange, high pitched, whining sound when I'm playing games like Skyrim and The Witcher 2. I just ran prime95 for 2 hours and the temps never went up higher than 50 degrees Celsius. And oddly, when running prime95 there were no strange noises at all.

Another odd thing is that when I'm playing Skyrim, there is a high pitched whining sound, but when I pause the game or go the the main menu, the noise disappears. The processor is being cooled with a Cooler Master Hyper 6 and I have never seen the processor overheating, it never got above 62 degrees Celsius after extensive testing.

Coil Whine from your power supply when it adjusts to the higher load needed to run games. - it's not the hard drive - the hard drive would make noise opening anything, not just games. The load is increased by the video card. Try running a video benchmark(like heaven), and see if it make the same noise.

This is the most likely issue.

I'm having an issue where I'm coil whining while idling. Strange because it's usually coil whine when you're under load :lol:  that's besides the point, though.

should I be worried?


Coil whine is more of an irritation than a problem, sometimes you can RMA your goods but I've heard reports that come manufacturers consider it normal behaviour and aren't interested except in very bad examples.

Contact the PSU manufacturer. As said above sometimes it can just be an annoyance while more often it can be indication of potential failure in the near future (perhaps from being insufficient since it seems to happen when your video card is engaged also).

Alright folks, I suppose it's nothing too dangerous. I just loaded the Witcher 2 and there was not a single sound coming from my PC (as usual I could only hear the air being transported from the 120mm fans). Kinda strange, when I was playing The Witcher 2 yesterday I could only hear that annoying coil whine.

Think of it as notify that the cpu is working over 80%-90% ;)  I have p4, 10 years right now, and have changed the psu (5-6 years ago?). Im almost sure that in the older psu there was this noise too.
