1.10.2 Internal connectors 1. Power, CPU and chassis fan connectors (3-pin PWR FAN, 4-pin CPU_FAN, and 4-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. 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 a CPU fan of maximum 2A (24 W) fan power. • Only the CPU_FAN and CHA_FAN connectors 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_FAN for better thermal environment. 2. Speaker connector (4-pin SPEAKER) This 4-pin connector is for the chassis-mounted system warning speaker. The speaker allows you to hear system beeps and warnings. ASUS F1A75-M LE 1-17
