5. Power, CPU, and Chassis Fan connectors

(3-pin PWR_FAN, 4-pin CPU_FAN, 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, 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. Insufcient air

ow 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 supports Q-Fan.
