• 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!
• Ensure that the 4-pin CPU fan cable is securely installed to the CPU fan connector.
• The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
• If you install two VGA cards, we recommend that you plug the rear chassis fan cable
to the motherboard connector labeled CHA_FAN1, CHA_FAN2, or CHA_FAN3 for
better thermal environment.
• The CPU_FAN connector and CHA_FAN connectors support the ASUS FAN Xpert 2
feature.
