CPU Fan Connectors
Please connect the CPU fan
(4-pin CPU_FAN1)
cable to the connector and
(see p.2 No. 5)
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.
ATX Power Connector
Please connect an ATX power
(24-pin ATXPWR1)
supply to this connector.
