I recently bought and built a new system. I'm experiencing a whirring / whining noise mainly when playing games. One thing to note is that the noise disappears when I Alt-Tab out of the game.
The noise always seems to be present but is tolerable when I'm not playing games, it's as if this noise gets faster or is amplified. Any thoughts and feedback is greatly appreciated as it's not a nice noise to get after spending £450.
If you need any more information let me know.
Mobo - GigaByte Z77-D3SH
CPU - Intel I5 3550k with Stock sink and fan
Ram - 2 x 4gb Corsair Vengeance LP
GPU - Powercolor Radeon HD6570
PSU - Corsair GS600
HDD - 160Gb
Case - Corsair Carbide 200R
My initial thought was the GPU but I'm really unsure. The sound is hard to explain almost like a ringing that when playing games has a similar sound to a hoover or jet engine (obviously nowhere near as loud as either)
If its not any fan making the noise, it could be coil whine. Coil whine can come from almost any component, most commonly on graphics cards. Though motherboards and PSU's have been known to do it. http://www.youtube.com/watch?v=HP73edpQwgc
Skip to 1:56 to hear it.
Fortunately my noise is not as high-pitched as that but I've done some more listening to my system components and I now know that it's the PSU. The noise seems to becoming more frequent, for example it will happen now even when logging into windows.
So apart from coil whine and fans what else can make noise in a PSU? Or could this be coil whine but of a different frequency?
I cant think of anything, I suspect its just coil whine of a different frequency.
Regardless though, unless you want to bust open that thing and find out (I advise not, the capacitors inside can hold a charge long after being disconnected from power and can kill),its still the PSU at fault.
Since manually fixing it isn't an option, replacing it is the only solution I can see.
Its likely that you could just replace it with the same PSU and it would be fine. I havent heard many issues of noise from Corsair supplies so yours must have a defect. Would just try replacing the unit without swapping to a different brand.
Good PSU manufacturers (other than Corsair) are XFX, Seasonic, Antec High Current, PC Power and Cooling and Silverstone's Strider Plus series.
