6. CPU, chassis, and power fan connectors
(4-pin CPU_FAN; 3-pin CHA_FAN1; 3-pin CHA_FAN2; 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.
• Only the CPU_FAN and CHA_FAN 1/2 connectors support the ASUS
Q-FAN 2 feature.
• If you install two graphics cards, we recommend that you plug the rear
chassis fan cable to the motherboard connector labled CHA_FAN1 or
CHA_FAN2 for better themal environment.
