6. CPU, chassis and power fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN1/2, 3-pin PWR_FAN)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
DO NOT forget to connect the fan cables to the fan connectors. Insufficient air flow inside
the system may damage the motherboard components. These are not jumpers! DO NOT
place jumper caps on the fan connectors!

• The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power.
• Only the CPU_FAN, CHA_FAN1 and CHA_FAN2 connectors support the ASUS Fan
Xpert feature.
• If you install two VGA cards, we recommend that you plug the rear chassis fan cable
to the motherboard connector labeled CHA_FAN1 or CAH_FAN 2 for better thermal
environment.
7. LPT connector (26-1 pin LPT)
The LPT (Line Printing Terminal) connector supports devices such as a printer. LPT
standardizes as IEEE 1284, which is the parallel port interface on IBM PC-compatible
computers.
