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!
• Ensure to fully insert the 4-pin CPU fan cable to the CPU fan connector.
• The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
• The CPU fan connector has a special latch that detects the installed CPU fan type and
automatically changes the fan control mode (DC mode and PWM mode) for the most
precise fan control function.
