High pitched whining sound from P55 UD3R?

[Mitsuru]

When I first purchased the P55 UD3R I noticed a horrible, constant whining sound. I'm not sure if the sound is coming from the CPU, the CPU cooler (unfortunately I'm still using the stock cooler until I can afford to upgrade) or the board itself. The sound comes from near the CPU area.

It's getting less frequent now, it only usually happens after I start my PC for the first time each day, then disappears after a while. It really is irritating though. I tried sticking a pencil in the fan blades which stopped the fan spinning for a few seconds, but the sound is still there. Could this be the board? Dodgy caps? Anyone else had a similar problem?

Just realized I haven't posted any specs:

P55 UD3R (BIOS F5b)
Core i5 750 (with minor OC due to garbage stock cooler)
Corsair HX520
2 x 2GB Patriot Viper II Sector 5 1600Mhz
nVidia 8600GT (soon to be replaced with ATI HD 5770)
Samsung Spinpoint F3 500GB SATA II
Optiarc AD-7200A (IDE)


The 8600GT definitely isn't a problem, I removed it and started up the PC with no GFX card. Whining sound remained.

I am using C1E. Since I wrote the opening post I saw a few threads where people mentioned disabling it, and this cured the whining sound. I really want to use C1E though, I'm not really happy about turning it off.

It seems the problem could be coming from the PSU?

yes its a common problem,even my board does it but if you disable c1e and you have windows 7 you can go in win7 power saving and select balanced power saving profile,it will then throttle the cpu when idle the same as c1e but without the high pitched squeal

It's that simple? Awesome! I have recently upgraded from XP to Win 7, so I will try it. Thanks very much for the info.

Seems to have done the trick. It's hitting the 9x multi when idle and also the 24x multi when under load using dynamic OCing. Great! Thanks again, Warren. I kinda wish I'd asked earlier instead of putting up with that screeching sound for the last month or so.
