• The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
• All the CPU and CHA fans support 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_FAN1-4 for better thermal environment.

system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
