6. CPU, chassis, and power fan connectors
(4-pin CPU_FAN; 3-pin CHA_FAN; 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. 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!
• The CPU_FAN connector supports the CPU fan of maximum 2A (24 W) fan power.
• Only the 4-pin CPU_FAN and 3-pin CHA_FAN 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_FAN for better thermal environment.
