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.
3-Pin Fan Installation
Pin 1-3 Connected
ATX Power Connector
Please connect a DC
(Input +12V & +19V~+24V)
