Fan Power Connectors: CPUFAN, SYSFAN1~3
The fan power connectors support system cooling fan with +12V. W hen connecting
the wire to the connectors, always note that the red wire is the positive and should
be connected to the +12V; the black wire is Ground and should be connected to GND.
If the mainboard has a System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.
IEEE1394 Connector: J1394_1 (Optional)
This connector allows you to connect the IEEE1394 device via an optional IEEE1394
bracket.

Important
1. Please refer to the recommended CPU fans at processor
’
s official website
or consult the vendors for proper CPU cooling fan.
2. CPUFAN1 supports fan control. You can install
Overclocking Center
util-
ity that will automatically control the CPU fan speed according to the actual
CPU temperature.
3. Fan cooler set with 3 or 4 pins power connector are both available for
CPUFAN1.
4. SYSFAN1 and SYSFAN2 support fan control, too. You may
select how per-
centage of speed for the SYSFAN1/2 in BIOS.
