CPU Middle Temperature [25]
Use the <+> or <-> keys to set the value for CPU Middle Temperature. The range of
the values depends on the CPU installed.
CPU Fan Middle Duty Cycle(%) [20]
Use the <+> or <-> keys to adjust the CPU fan middle duty cycle. The values range
from 20% to 100%. When the CPU temperature reaches the upper limit, the CPU fan
operates at the maximum duty cycle.
CPU Lower Temperature [25]
Use the <+> or <-> keys to adjust the CPU fan's lower temperature. The values range
from 0°C to 75°C.
CPU Fan Min. Duty Cycle(%) [20]
Use the <+> and <-> keys to adjust the minimum CPU fan duty cycle. The values
range from 20% to 100%. When the CPU temperature is under the lower limit, the CPU
fan will operate at the minimum duty cycle.
