6. CPU, chassis, and power fan connectors
(4-pin CPU_FAN; 4-pin CHA_FAN1/2/3; 3-pin PWR_FAN)
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 2A (24 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,
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!
