PSU Fan as Case Fan

Hi,

I'm interested in taking a very old PSU Fan and using it as a Case Fan. I'm wondering if there are any issues with doing that? The cable connected to the fan only uses 2 pins (which I guess I'll put for 12v and rotation), so it probably doesn't have a ground. If I connect this fan to my new motherboard would it put it as risk?


Thanks!

  1. That depends on how much current it draws. Post the information on the fan.

    You are certainly safe running it directly off the PSU, obviously.
  2. it says on it..

    DC12V 0.12A

    also more info... it has the red and black wire, I know black is ground, and red is 12V? So it should be ok?
  3. It would be nice to know the mobo in question, but I can safely say that fan at .12A will be fine. You might have a situation that the fan won't spin when the mobo is trying to make it spin slow. To eliminate this, remove any mobo fan speed control and it should spin. There should be a number next to the term CFM, which stands for cubic feet per minute. You may want to compare this number with similar sized fans on Newegg to determine whether it is pushing enough air for you.
