My computer power supply fan does not run.?

Then I removed the power supply and plugged the power cord in the diode turned on and all voltages were good, and the fan did not run and the fans' red and black connections on the circuit board were dead. Then I thought perhaps the fan might not power up unless the leads were plugged into the motherboard. Is this correct? If so it could be the fan itself is bad. I need to know cause it is a HIPRO, a good one, and takes about 20 minutes to get apart. Also a new OEM PS costs $65, the fan costs three. Most cheap replacement PS are junk. Thanks!

You need to connect the PSU to a motherboard to turn it on, then you can tell if the fan is running good or not. If the fan has gone bad but still spinning, in a lot of cases you can apply a lubricant to fix it, or replacing it totally if it doesn't work anymore.
