CPU Smart FAN Control
Enables or disables the CPU fan speed control 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: Enabled)
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.
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.
