CPU and chassis fan connectors (4-pin CPU_FAN and 3-pin CHA_FAN)
The fan connectors support cooling fans of 350mA~740mA (8.88W max.) or a total of

1A~2.22A (26.64W 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.

Only the 4-pin CPU fan supports the ASUS Q-Fan feature.

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.
