4-pin PWM Fan Pin Assignment
These 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.
The 4-pin fan provides PWM to modulate fan speed whereas the 3-pin fan does not.
BIOS Setting
Configure the Smart Fan function in the Advanced menu (“SIO NUVOTON6116D” submenu) of
the BIOS. Refer to chapter 3 for more information.
