CPU and chassis fan connectors (4-pin CPU_FAN and 3-pin CHA_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.
Only the 4-pin CPU fan supports the ASUS Q-Fan feature.
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.
