ASUS P8Z77-V PRO Technical Updates
This is an information update for the user guide that comes with your motherboard package.
CPU and chassis fan connectors
(4-pin CPU_FAN; 4-pin CPU_OPT;4-pin CHA_FAN1-4)
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.
(page 2-23)
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!
The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
All the CPU and CHA fans support 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_FAN1-4 for better thermal environment.
