Connect the CPU fan's cable connector to the CPU fan connector
on the system board. The 2nd fan and system fan 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 "PC Health Status" submenu of the BIOS will display the current
speed of the cooling fans. Refer to chapter 3 for more information.
