Hardware Installation
2.6.7 Chassis Fan and 2nd Chassis Fan Connectors
The chassis fan connector (J11) and second chassis fan connector
(J12) are used to connect cooling fans. The cooling fans will pro-
vide adequate airflow throughout the chassis to prevent over-
heating the CPU and system board components. The system is
capable of monitoring the speed of the chassis fan.
BIOS Setting
The "PC Health Status" submenu of the BIOS will display the
current speed of the chassis fan. Refer to chapter 3 for more
information.
