Fan Speed Up When CPU Temp
Enables 3 phase smart controls to the Selected fan. This feature ranges
from 40 C to 52
0
Ø The choice: 40
If actual CPU temp (reported by BIOS) stays below 48
speed will run at a quiet mode (1st phase) of approximately 2000
RPM.
But when the actual CPU temp goes above the preselected 48
temperature threshold, then CPU fan speed will automatically engage
into normal mode (2nd phase) of about 3000 RPM and cool down
the CPU temperature. When the CPU temperature drops back below
the 48 C temperature threshold, CPU fan speed will again automati-
0
cally shift back to the quiet mode (1st phase) to reduce fan noise level.
Fail-safe mode (3rd phase) Variable Fan Speed and CPU temperature
Control is as predefined at 52
CPU operating under extreme working conditions, and if CPU tempera-
ture is raised above 52
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 to
compensate for the increase in CPU temperature.
