Make sure it's still connected to the mainboard - if it is, you can order a replacement from

The processor fan is the one behind the CPU affixed to the back of the case.

The other fan is inside the power supply (it sounds like it's not that one which  has failed).

Thanks, so there is a processor fan?

I can feel the big fan running, there are two? 

Thanks for your detailed information. I did find it, and made sure it was plugged in. It's not turning so I assume it's bad.

I'm not real computer smart and broke all four of those rubber things that hold the fan in when I removed it.

I will use the link you provided to order a new fan. Hope it comes with screws or something

Thanks again 

Not sure if we're suppose to follow up.

Got the new fan, put it in, problem solved

Thanks
