After I took out one of my harddrives, which I noticed showed some errors, I heard my PSU started making electrical noises. I first found that out when I ran HD tune, that's when the noise is at its loudest. During prime95, there's no sound at all. It really seems load dependent, somehow. I'm 110% sure it is coming from the PSU, not the CPU socket area. Below is a recording of the sound, turn your sound way up. During this recording I'm starting HD tune twice, which is when the noise starts.
I already contacted my vendor and they said PSU's sometimes just start doing that, and I can RMA it if I wanted. However, after having read something about disabling C1E that might resolve the issue, I'm not sure anymore. Also right now I'm still in the process of finding out whether my system is stable (memory related BSOD's, my other topic here). So I don't feel anything for other weird crashes related to changing bios settings like EIST, C1E or whatever. If you ask me, the PSU just went bad and I'm thinking about returning it once I'm sure my system and memory are stable. But please give me your opinion on this.

Coolermaster Realpower M620p.s. I don't think my PSU caused the apparent memory related BSOD's: the system is stable in overnight memtest and prime95.
