Cooling Fan Connectors
Connect the CPU fan’s cable connector to the CPU fan connector
(J31) on the system board. 1st fan (J9), 2nd fan (J6), 3rd fan (J17),
NB fan (J30) and System fan (J32) are used to connect additional
cooling fans. The cooling fans will provide adequate airflow through-
out 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.
