Hardware Installation
Cooling Fan Connectors
Connect the CPU fan’s cable connector to the CPU fan connector
(J12) on the system board. The system fan J13), fan 1 (J23), fan 2
(J8) and fan 3 (J15) connectors are used to connect additional cool-
ing fans. The cooling fans will provide adequate airflow throughout
the chassis to prevent overheating the CPU and system board com-
ponents.
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.
