The fan connectors support cooling fans. 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!
• All fans feature the ASUS Smart Fan technology.
