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, CHA_FAN1, and CHA_FAN2 connectors support
the ASUS Q-Fan 2 feature.

•

CHA_FAN1 and CHA_FAN2 use the same Q-Fan 2 controller.

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!

better thermal environment.
