Please connect the CPU fan cable to the connector and match the black wire to the ground pin.

 

Though this motherboard provides 4-Pin CPU fan (Quiet Fan) support, the 3-Pin

 

CPU fan still can work successfully even without the fan speed control function.

 

If you plan to connect the 3-Pin CPU fan to the CPU fan connector on this

 

motherboard, please connect it to Pin 1-3.
