Cooling Fan Connectors
Connect the CPU fan’s cable connector to the CPU fan connector
(J31) on the system board. Fan 1 (J9), Fan 2 (J6), Fan 3 (J32), Fan 4
(J12) and NB Fan (J30) are used to connect additional cooling fans.
The cooling fans will provide adequate airflow throughout the chassis
to prevent overheating the CPU and system board components.
BIOS Setting
The “PC Health Status” submenu of the BIOS will display the current
speed of the cooling fans. Refer to chapter 3 for more information.
