fan will operate at maximum duty cycle in full speed.
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 cannot be lower than the setting of the
Min. Duty Cycle.
CPU Lower Temperature [20] (in celsius)
Displays the lower limit of the CPU temperature. Users can set the CPU Fan Min.
Duty Cycle when CPU temperature is lower than the CPU Lower Temperature
setting.
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 20°C, the CPU fan will
operate at the minimum duty cycle.
