F2A85-M PRO Fan connectors

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.

• The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power.

•Only the CPU_FAN and CHA_FAN1/2/3 connectors support the ASUS Fan Xpert 2 feature.

•If you install two VGA cards, we recommend that you plug the rear chassis fan cable to the motherboard connector labeled CHA_FAN1/2 for better thermal environment.
