10. CPU, Chassis, and Power Fan connectors (4-pin CPU_FAN,
3-pin PWR_FAN, 3-pin CHA_FAN1, 3-pin CHA_FAN2)
The fan connectors support cooling fans of 350 mA ~ 2000 mA (24
W max.) or a total of 1 A ~ 3.48 A (41.76 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.
Only the CPU_FAN and CHA_FAN1 connectors support the
ASUS Q-Fan 2 feature.
Do not forget to connect the fan cables to the fan connectors.
Insufcient air ow inside the system may damage the motherboard
components. These are not jumpers! Do not place jumper caps on the
fan connectors!
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.
