4. CPU and chassis fan connectors (3-pin CPU_FAN, 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!
