Question CX600M weird fan issue

[herman.eggink]

Hope anyone can help me: I have a small system with a CX600M power supply. The fan itself runs at a relatively low speed but every once in a while it slows down (couple of times in a row) making a whirring noise (like a vibration) before spinning back up to its usual low rev state. Does that a couple of times and then the cycle starts again after a couple of minutes.

Any thoughts? When the fan runs at the regular speed, there is no noise at all, only when it momentarily spins down a bit. It does not come to a complete stop tho.

Help appreciated!!

Could be the way the psu is made (don't quote me on that), or could be an internal issue, either way i'd recommend for you to check your psu's voltages via your motherboard's BIOS or HWInfo (Less accurate)

Go onto your bios, (Spam F8 or Delete on boot) and then go into the advanced tab and look at your psu's voltages, refer to this image for the voltage range you should be in.

Report voltages back here.

The voltages were all spot on: 12.091V, 5.112V, 3.328V, CPU core 1,216.
So that all seems fine...
Thanks for the fast reply btw!

Voltages seem good, just keep an eye on your psu for any issues, and check your voltage every so often to make sure it's alright, as for the noise, no idea man.
