Chapter 1: Product introduction
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. 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 supports Q-Fan.
