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?
