Owner's Manual

ASUS Z87-C
1-32
The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
The CPU_FAN connector and CHA_FAN 1-3 connectors support the 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_FAN1-3 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!

(4-pin CPU_FAN; 4-pin CPU_OPT; 4-pin CHA_FAN1-3)
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.
