English Smart FAN Control Method (Note) Specifies how to control CPU fan speed. Auto Lets BIOS control CPU fan speed. (Default) Intel(R) QST Allows CPU fan speed to be controlled by the Intel Quiet System Technology (QST). This feature requires the installation of Intel Host Embedded Control Interface (HECI) driver from the motherboard driver disk. Legacy Disabled Allows CPU fan to run at different speed according to the CPU temperature. Forces CPU fan to run at full speed. Smart FAN Control Mode Auto Lets BIOS autodetect the type of CPU fan installed and sets the optimal CPU fan control mode. (Default) Voltage PWM Sets Voltage mode for a 3-pin CPU fan. 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. (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.

Smart FAN Control Method
(Note)
Specifies how to control CPU fan speed.
Auto
Lets BIOS control CPU fan speed. (Default)
Intel(R) QST
Allows CPU fan speed to be controlled by the Intel Quiet System Technology
(QST). This feature requires the installation of Intel Host Embedded Control
Interface (HECI) driver from the motherboard driver disk.
Legacy
Allows CPU fan to run at different speed according to the CPU temperature.
Disabled
Forces CPU fan to run at full speed.
Smart FAN Control Mode
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.
(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.
