Internal connectors

1.

Power, CPU and chassis fan connectors (3-pin PWR FAN, 4-pin CPU_FAN, and

4-pin CHA_FAN1)
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 a CPU fan of maximum 2A (24 W) fan power.
• Only the CPU_FAN and CHA_FAN1 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 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.

helps enhance network security, protects digital identities, and ensures platform

integrity.
