The following four items appear only when you set CPU Fan Prole to [Manual].
CPU Upper Temperature [70]
Use the <+> and <-> keys to adjust the upper limit of the CPU temperature. The values range
from 20ºC to 75ºC.
CPU Fan Max. Duty Cycle(%) [100]
Use the <+> and <-> keys to adjust the maximum CPU fan duty cycle. The values range from
0% to 100%. The minimum value can not lower than the setting of Min duty cycle. When the
CPU temperature reaches 75 degree, fan will run up to full speed.
CPU Lower Temperature [20]
Displays the lower limit of the CPU temperature.
CPU Fan Min. Duty Cycle(%) [20]
Use the <+> and <-> keys to adjust the minimum CPU fan duty cycle. The values range from 0%
to 100%. When the CPU temperature is under 40ºC, the CPU fan will operate at the minimum
duty cycle.
