1. CPU, chassis, and power fan connectors
(4-pin CPU_FAN; 4-pin CHA_FAN1; 3-pin CHA_FAN2; 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 2A (24 W) fan power.
• Only the 4-pin CPU fan and chassis fan 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 1/2 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.
