CPU Smart FAN Control

Enables or disables the CPU fan speed control function. Auto lets the BIOS decide whether to enable this function. Enabled allows the CPU fan to run at different speed according to the CPU temperature. You can adjust the fan speed with EasyTune based on system requirements. If disabled, CPU fan runs at full speed. (Default: Auto)

CPU Smart FAN Mode

Specifies how to control CPU fan speed. This item is configurable only if CPU Smart FAN Control is set to Enabled or Auto.

Auto	Lets BIOS autodetect the type of CPU fan installed and sets the optimal CPU
	fan control mode.
Voltage	Sets Voltage mode for a 3-pin CPU fan.
PWM	Sets PWM mode for a 4-pin CPU fan. (Default)

Note: The Voltage mode can be set for a 3-pin CPU fan or a 4-pin CPU fan. However, for a 4-pin CPU fan that is not designed following Intel PWM fan specifications, selecting PWM mode may not effectively reduce the fan speed.
