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.

inside the system may damage the motherboard components. These are not jumpers!
Do not place jumper caps on the fan connectors!
• Ensure that the CPU FAN cable is securely installed to the CPU fan connector.
• The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
• The CPU_FAN, CHA_FAN and ASST_FAN connectors support the TUF Thermal
Radar 2 feature.
• To fully use the fan control function, ensure that you connect only an assistant fan to
the ASST_FAN connectors.
