• DO NOT forget to connect the fan cables to the fan headers. Insufficient air flow
inside the system may damage the motherboard components. These are not
jumpers! Do not place jumper caps on the fan headers!
• Ensure the cable is fully inserted into the header.
For water cooling kits, connect the pump connector to the AIO_PUMP header.
