ASUS Commando

2-31

7. CPU, chassis, power, and optional fan connectors

(4-pin CPU_FAN, 3-pin CHA_FAN1, 3-pin CHA_FAN2, 3-pin CHA_FAN3,

3-pin PWR_FAN, 3-pin OPT_FAN1~3)
The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W max.)

or a total of 1 A ~ 7 A (84 W max.) at +12V. Connect the fan cables to the

fan connectors on the motherboard, making sure 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!

• CPU_FAN, CHA_FAN1~3, and OPT_FAN 1~3 connectors support the

ASUS Q-FAN 2 feature.

• If you install two VGA cards, we recommend that you plug the rear chassis

fan cable to the motherboard connector labeled CHA_FAN2 for better

themal environment.
