Tick tick tick... should I be worried? (audio files included)

post #1 of 2
Thread Starter 
My power supply is a Thermaltake W0319RU (850W). I received it last summer after doing an RMA for my W0106RU (700W, discontinued).

I have noticed that the power supply is making a faint ticking noise. Ticking rate seems to be about 1500 per minute. I am assuming the source of the noise is probably the fan.

tick1.wma (146 kB) - unedited, recorded via usb boom mic
tick2.wma (171 kB) - modified in Adobe Soundbooth, ticking enhanced, fans decreased

General impressions? Should I be worried? Should I RMA? Is this common? Does anyone else have this sort of noise coming from their PSU?

Thanks!

Side note 1, yes, I'm probably OCD. Not really. But really now. Come on.

Side note 2, Sabertooth Z77 motherboard, just installed the AI Suite and set up silent fan profiles... so awesome. Especially now that those damned Motherboard Assistant fans are turned down. Geebus, 35mm FTL.

    I think it's the fan.  I believe that you're fine with this PSU.  If you want to verify that it is the fan, find a soft object to stick in the grill and temporarily pin the fan with it.  If the noise stops, it is the fan.
