Cooling Fan Connectors
Connect the CPU fan’s cable connector to the CPU fan connec-
tor (J13) on the system board. Connect the Intel 875P fan’s cable
connector to the NB fan connector (J27) on the system board.
The chassis fan (J19) and second fan (J25) connectors 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 system is capable of monitoring the speed of the CPU fan,
NB fan and chassis fan. The “PC Health Status” submenu of the
BIOS will display the current speed of these cooling fans. Refer
to chapter 3 for more information.
More Information

tection function.
