Well, I have a Coolmax 500W PSU that has a 120mm fan. Its a very nice PSU for the price (has SATA connectors and several other nice features). I used to have it in my own rig, but I'm selling that one. Never had any problems with it, though. If you need good inexpensive power, its great. Personally though, I wouldn't trust it with heavy OCs. Of course thats why I've got a 480W Neopower in my new rig.
