Cooling Fan Connectors
The fan connectors are used to connect cooling fans. The cooling fans will provide adequate
airflow throughout the chassis to prevent overheating the CPU and system board components.
BIOS Setting
The Advanced menu (“SIO NUVOTON6116D” submenu) of the BIOS will display the current
speed of the cooling fans. Refer to the chapter 3 for more information.
