8. CPU, chassis, and power fan connectors (4-pin CPU_FAN; 4-pin CPU_OPT;
4-pin CHA_FAN1/ CHA_FAN2/ CHA_FAN3; 4-pin OPT_FAN1/ OPT_FAN2 /
OPT_FAN3)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the 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.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside the
system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
