CPU Smart FAN Mode
This option is available only when CPU Smart FAN Control is enabled.
Auto
BIOS autodetects the type of CPU fan you installed and sets the optimal CPU Smart
FAN control mode for it. (Default value)
Voltage
Set to Voltage when you use a CPU fan with a 3-pin fan power cable.
PWM
Set to PWM when you use a CPU fan with a 4-pin fan power cable.
Note: In fact, the Voltage option can be used for CPU fans with 3-pin or 4-pin power cables.
However, some 4-pin CPU fan power cables are not designed following Intel 4-Wire fans PWM
control specifications. With such CPU fans, selecting PWM will not effectively reduce the fan
speed.
