I recently built a computer, and everything is running smoothly, but the rear case fan is not spinning. It doesn't even spin a bit at startup and then stop, it just won't spin. It is a 120 mm tricool fan from Antec, the fan that comes with the Antec Sonata iii 500 case. It is plugged into a Corsair tx-650 PSU. Help would be very appreciated.
 


That's how I originally had it, but it didn't spin like that either, so I tried it in the PSU. Also the fan header is 4 pins and the Fan's plug is a 3 pin socket.
 


3 pin fans work on 4 pin headers

 


Problem solved. I plugged it into the motherboard fan header and it works. Thanks a bunch!
