13 . CPU, Chassis, NorthBridge, and Power Fan connectors (4-pin CPU_FAN, 3-pin PWR_FAN, 3-pin CHA_FAN1, 3-pin CHA_FAN2, 3-pin NB_FAN)

The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W max.) or a total of 1 A ~ 3.48 A (41.76 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.

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 and CHA_FAN1 connectors support the ASUS Q-Fan 2 feature.

¥The ASUS Q-Fan 2 feature is available in the Deluxe model only.

¥ Install an additional chassis fan when you are using two PCI Express graphics cards or a dual-core processor for better thermal environment.

¥For some chassis models with short 3-pin chassis fan cable, connect the cable to the NB_FAN connector.

¥Make sure to change the fan power jumper (FANSEL) when using a 3-pin CPU fan.
