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. (Default)
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 fan that is not designed following Intel PWM fan specifications, selecting PWM mode may not
effectively reduce the fan speed.
