PSU fan stopped, noisy, yet cool, wtf?

I have an antec 500W psu (model sp-500). The exterior facing fan is not moving, and won't work with a flick-start, but the case of the psu is extremely cool (room-temperature cool). Do I need to fix/replace the fan?

Also it's making a strange noise about every 10 seconds, a whirring sound like something is winding up faster and faster for about 2 seconds and then stopping fast. The exterior-facing fan is not moving when this happens, and placing my hand in front of the interior-facing fan, I don't feel any difference in air flow. It sounds like it's coming from inside the psu...any ideas what's up?

Thanks in advance.

  1. stuff breaks and cheapy 500w psu's get chearpy fans!

    get a new psu!
  2. My chip fan and (occasionally) CPU fan often don't work, could the PSU be causing this, even though it's not warm, or is it a mobo problem?
  3. As far as I know, PSU fans don't automatically turn off. o_O Your PSU fan is toast, and that whirring sound could possibly be a blown capacitor or something. I don't know though; not a PSU expert.

    With that said, check your Antec warranty and get it replaced. In the meantime, get a better PSU perhaps...
