If you are installing a chassis fan in the system unit, connect the fans
connector to J21 on the system board. The fan will provide
adequate airflow throughout the chassis to prevent overheating the
processor. The system is capable of monitoring and controlling the
speed of the chassis fan. It will automatically turn off once the system
enters the Suspend mode.
