8. CPU, chassis, and power fan connectors
(4-pin CPU_FAN/CPU_FAN_OPT; 4-pin CHA_FAN1; 3-pin CHA_FAN2; 3-pin
PWR_FAN1/2)
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.
The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
Only the CPU_FAN, CHA_FAN 1 and CHA_FAN 2 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 CHA_FAN2 for better thermal
environment.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside the
system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
