New PC Build – Odd whistling noise

I have recently built my own PC. After suffering on various Dell machines, which were completely locked down and not possible to do any kind of over clocking, I finally decided to take a leap of faith and build my own…

Asus P6X58D-E Motherboard, Intel Core i7 930, ATI 5850, 6GB Corsair RAM, Corsair 650w PSU, Akasa Raptor case

After building it, and then switching it on, I noticed a rather annoying whistling noise coming from somewhere within the PC case. On closer inspection (with my ears, obviously) I discovered it was coming from somewhere on the Motherboard, even the processor itself(!). Now I realise that processors don’t make odd whistling noises, so it’s something close to the CPU socket on the motherboard itself. But what? It’s not any of the fans because I briefly unplugged them and the noise continued.

After a bit of googling, it seems that this problem could be fairly widespread. I tried disabling C1E and speedstep and manually setting voltages and CPU multi’s, but nothing worked and it still whistles.

Oddly, it doesn’t do it as much under load – only really when idling…. Very odd.

I could return the board, but after building it all it seems too much of a hassle really to have to undo everything just to see if a new motherboard would fix it.
