CPU Smart FAN Control

Allows you to determine whether to enable the CPU fan speed control function and adjust the fan speed.

Normal Allows the CPU fan to run at different speeds according to the CPU temperature. You can

adjust the fan speed with EasyTune based on your system requirements. (Default)

Silent Allows the CPU fan to run at slow speeds.

Manual Allows you to control the CPU fan speed under the Slope PWM item.

Disabled Allows the CPU fan to run at full speeds.

Voltage Sets Voltage mode for a 3-pin CPU fan.

PWM Sets PWM mode for a 4-pin CPU fan.

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
