If you want to use the printer port function, please
short pin4
and pin5 on
Digital Input / Output Power Select (JGPIO_PWR1).
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
4-pin ATX PWR Con Please connect a DC
(Input +12V or +19V~+24V) +12V or +19V~+24V power
(4-pin ATX12V1)
supply to this connector.
(see p.8 No. 5)
1-2: GND
3-4: DC Input
CPU Fan Connector Please connect the CPU fan
(4-pin CPU_FAN1)
cable to the connector and
(see p.8 No. 3)
match the black wire to the
ground pin.
ATX Power Connector Please connect an ATX power
(20-pin ATXPWR1)
supply to this connector.
