The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
•
Only the CPU_FAN and CHA_FAN1/2/3/4 connectors support the ASUS Fan Xpert+

If you install two or three (the most) VGA cards, we recommend that you plug the rear
chassis fan cable to the motherboard connector labeled CHA_FAN1 or CHA_FAN2 for
better thermal environment.
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!
