7. CPU�� chassis�� and power fan connectors
(4-pin CPU_FAN�� 4-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.
• The CPU_FAN connector supports the CPU fan of maximum 1A (12 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 CHA_FAN2 for better thermal
environment.
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!
