If you are installing a chassis fan in the system unit, connect the fans
connector to location J19 on the system board. The fan will provide
adequate airflow throughout the chassis to prevent overheating the
CPU. 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.
