I checked the connection on the motherboard.  The other end is connected 
inside the fan assembly; how do I check that end?  Nothing appears damaged.

I assembled from the User Guide.  I am confident it is the correct 
place.  On the motherboard it says CPU_F under the pins.

My power supply bound the 20 and 4 pin connectors together so you can't 
make that error.

Thanks for the quick reply.  I turned the computer off as soon as I 
noticed the fan wasn't running, so with your explanation, I am more at ease.
