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 connectors support the ASUS Fan Xpert 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. 1-20 Chapter 1: Product introduction
