8. CPU and chassis fan connectors

(4-pin CPU_FAN, 4-pin CHA_FAN1/2)

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.

• 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. 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!
