CPU, chassis and power fan connectors

(4-pin CPU_FAN, 3-pin CHA_FAN1-2, 3-pin PWR_FAN)
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!

Only the CPU-FAN and CHA-FAN 1-2 connectors support the ASUS Q-Fan

feature.
