Take our default Setting for example, 1st and 2nd phase Variable Fan
Speed and CPU temperature Control is as defined by "Fan Speed Up
When CPU Temp." If actual CPU temp (reported by BIOS) stays below
72
0
C then CPU fan speed will run at a quiet mode (1st phase) of
approximately 2000 RPM.
But when the actual CPU temp goes above the preselected 72
0
C
temperature threshold, then CPU fan speed will automatically engage
into normal mode (2nd phase) of about 3000 RPM. Automatically by
the Smart Bios feature, this increase of fan rotation speed will effectively
cool down the CPU temperature. And when the CPU temperature
drops back below the 72
0
C temperature threshold, CPU fan speed will
again automatically shift back to the quiet mode (1st phase) of about
2000 RPM in order to reduce fan noise level.
Fail-safe mode (3rd phase) Variable Fan Speed and CPU temperature
Control is as predefined at 80
0
C. Where in the event of system and
CPU operating under extreme working conditions, and if CPU tempera-
ture is raised above 80
0
C then the Smart Bios will engage the CPU fan
in Fail-safe mode to rotate at about 3500 RPM. Please note that the
higher fan speed, the fan cooler will be become slightly noiseier in
order to compensate for the increase in CPU temperature.
Warning: It is strongly recommended to disable CPU Fan AutoGuard-
ian feature, if you wish to use other fan cooler, allowing the fan to run
at its default speed.
