10. CPU, chassis, and power fan connectors

(4-pin CPU_FAN, 4-pin CHA_FAN1, 3-pin CHA_FAN2, 3-pin PWR_FAN)
The fan connectors support cooling fans of 350 mA~1000 mA (12 W max.) or a total

of 1 A~4 A (84 W max.) at +12V. 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!

Only the CPU_FAN, CHA_FAN 1, and CHA_FAN 2 connectors support the 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 or CHA_FAN2 for better thermal

environment.
