Smart FAN Control Mode
Auto
BIOS autodetects the type of CPU fan you installed and sets the optimal fan
speed 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.
(Note) Before setting this item to Intel(R) QST, make sure at least DDRII1 or DDRII2 socket in Channel
0 is populated. A small portion of system memory will be shared when Intel
®
QST is enabled.
