The chassis fan connector (J15) and 2nd fan connector (J12) are
used to connect cooling fans. The cooling fans will provide ad-
equate airflow throughout the chassis to prevent overheating 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.
