3-46
CPU Upper Temperature [70]
Use the <+> or <-> keys to adjust the upper limit of the CPU temperature.
The values range from 25°C to 75°C.
CPU Fan Max. Duty Cycle(%) [100]
Use the <+> or <-> keys to adjust the maximum CPU fan 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 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
middle value, the CPU fan operates at the middle duty cycle.
CPU Lower Temperature [20]
Use the <+> or <-> keys to adjust the CPU fan's lower temperature. The
values range from 20% to 75%.
CPU Fan Min. Duty Cycle(%) [20]
Use the <+> or <-> keys to adjust the minimum CPU fan duty cycle. The
values range from 20% to 100%. When the CPU temperature is under
20°C, the CPU fan operates at the minimum duty cycle.
Set to make the chassis fan adjust automatically depending on the
chassis temperature.
Set to minimize the fan speed for quiet chassis fan operation.
Set to achieve maximum chassis fan speed.
Set to assign detailed fan speed control parameters.
