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!

•

Only the CPU_FAN, CHA_FAN 1, and CHA_FAN 2 connectors support the 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 or CHA_FAN2 for better thermal

environment.
