CPU and chassis fan connectors (4-pin CPU_FAN, and 4-pin CHA_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.

•

The CPU_FAN and CHA_FAN connectors support the ASUS Fan Xpert feature.
