English Smart FAN Control Method 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 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. (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.

English
Smart FAN Control Method
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
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.
(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.
