Anyone else notice a high pitched squealing sound coming from someplace around the CPU socket when the system is under load? My system is very quiet (water cooled with low-rpm fans) so it becomes very noticeable. With the case open, just try to put your ear over the CPU socket while starting and stopping Prime95 or IntelBurnTest. I'm using a Q9550 @ 4Ghz but noticed this noise even running stock speed and voltages.

Guess it's caused by the issue discsussed in this article:

Just wondering if all EP45-UD3P boards are affected or only a few. I still have time to exchange this board if this is a rare problem.

Thanks.
