Rear Exhaust Fan Not Spinning

Hello,

I have just noticed that the area around my PSU is getting really hot and I checked to see what the issue was. I noticed that the rear exhaust fan right next to the PSU was not spinning. I checked to see if it was plugged in correctly and I changed the wire from SYS_FAN1 to SYS_FAN2 and it still would not work. The fan came with my case. It would be appreciated if anyone could help.

Thanks, Landon

The rear exhaust fan is most likely the hardest working one in your case, find an exact replacement on Amazon or Newegg and order a replacement. It is most likely dead if you tried another power source on your board.

You could try checking in the BIOS what are the fan settings. 

But the fan/wire might have failed.

Why?

Just find a fan of the same size, not necessarily the same. Chances are that fans that come with cases are not that high quality. OP might want to get a better fan overall.

I already checked the BIOS, nothing there helped. The fan settings were all set to normal.

You might want to replace the fan then.

Good catch on my assumption on the quality of fan, My few cases are of better quality and provide good high static pressure fans. I suppose an OEM computer would have junk fans.

You can try to connect it directly to PSU. But 2 headers dying at the same time isn't likely. So fan shopping you go.
