Asus F2A55 Computer Hardware User Manual


 
1.8.2 Internal connectors
1. CPU and chassis fan connectors (4-pin CPU_FAN, and 4-pin CHA_FAN1/2)
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 a CPU fan of maximum 2A (24 W) fan power.
Only the 4-pin CPU fan and 4-pin chassis fan support the ASUS 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_FAN1/2 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.
