10. CPU, Chassis and Power Fan connectors (4-pin CPU_FAN, 3-pin CHA_FAN, 3-pin
PWR_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 CPU Fan supports Q-Fan.
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.
