Sound from PSU?

[misterme2009]

There is a strange sound coming from my power supply as if something is making contact with one of the fans. Problem is it's actually inside the PSU itself, so I'm not sure how to fix it. I tried sticking a pencil in and trying to turn the fans with it, and there seems to be no resistance, so it must be a very slight thing. Any ideas?

Thanks

you could open it, but I suggest not...unless you are comfortable with such tinking...have a canister of compressed air? try that...with everything turned off and unplugged...and again...all you, not my responsibility

you are thinking this is the psu fan and not another than?
also try a vacuum cleaner...suck some dust out and see if that clears it

Shake the PSU around a bit.
