Hardware Installation
2.6.8 Cooling Fan Connectors
Connect the CPU fan’s cable connector to the CPU fan connec-
tor (J1) on the system board. Connect the Intel 875P fan’s cable
connector to the Chip fan connector (J4) on the system board.
The chassis fan (J24) and second fan (J18) 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.
The system is capable of monitoring and controlling the speed of
the chip fan and second fan. These fans will automatically turn off
once the system enters the Suspend mode.
BIOS Setting
The “PC Health Status” submenu of the BIOS will display the
current speed of the CPU fan, chip fan and second fan. Refer to
chapter 3 for more information.
More Information
Refer to appendix B for information on using the CPU Fan Pro-
tection function.
