Hey, so I just put together a new system. I noticed a strange whirring coming from the build after I put it together when it was running with some load.

What seems to be happening is that the fan does not run when the system is not running anything, but then kicks on intermittently when the system is under load. But the weird thing is that the fan doesn't stay on under load: it turns on for a period of a few seconds, then turns off, then does it again, and repeats this cycle somewhere between every 35-55 seconds.

I know the GS600 is designed to not need the PSU fan when it isn't running under much stress, but I don't know why, even when it is running under a relatively constant level of stress, the fan seems to intermittently turn off and on.

Here is the system configuration:

AMD FX-8320
ASUS M5A97 R2.0
PowerColor 7850 2GB 2GBD5-DH
16 GB (2x8gb) Kingston HyperX 1600mhz
LG Blu-Ray Drive
OCZ Vertex Plus OCZSSD2-1VTXPL60G.RF
Western Digital Caviar Blue 500GB HDD
Zalman CNPS5x CPU Cooler
Rosewill Challenger Case
Corsair GS600 PSU
