CPU Smart FAN Control
Disabled Disable this function.
Enabled Enable CPU Smart Fan control function. (Default value)
a. When the CPU temperature is higher than 65 degrees Celsius, CPU fan
will run at full speed.
b. The speed of CPU fan will increase linearly depand on the temperature if
the temperature is more than 41 degree and less than 65 degree.
c. When the CPU temperature is lower than 40 degrees Celsius, CPU fan will
be disable.
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.
