10. CPU, chassis, and power fan connectors

(4-pin CPU_FAN; 4-pin CPU_OPT; 4-pin CHA_FAN1/2/3; 4-pin OPT_FAN1/2/3)
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. Insufficient air flow inside the

system may damage the motherboard components. These are not jumpers! Do not place

jumper caps on the fan connectors!
