CPU Fan Profile [Standard]
This item allows you to set the appropriate performance level of the CPU fan.
[Standard] Set to make the CPU fan adjust automatically depending on the CPU
temperature.
[Silent] Set to minimize the fan speed for quiet CPU fan operation.
[Turbo] Set to achieve maximum CPU fan speed.
[Manual] Set to assign the detailed fan speed control parameters.
The following items appear only when you set the CPU Fan Profile to [Manual].
CPU Upper Temperature [70]
Use the <+> or <-> keys to adjust the upper limit of the CPU temperature.
The values range from 20 to 75.
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 will operate at the maximum duty cycle.
CPU Middle Temperature [25]
Use the <+> or <-> keys to adjust the middle limit of the CPU temperature.
The values range from 20 to 75.
CPU Fan Middle. Duty Cycle (%) [20]
Use the <+> or <-> keys to adjust the middle CPU fan duty cycle. The
values range from 20% to 100%. When the CPU temperature reaches the
middle limit, the CPU fan will operate at the middle duty cycle.
CPU Lower Temperature [20]
Use the <+> or <-> keys to adjust the lower limit of the CPU temperature.
The values range from 20 to 75. The CPU fan will operate at the minimum
duty cycle when the temperature is lower than the limit.
CPU Fan Min. Duty Cycle(%) [20]
Use the <+> or <-> keys to adjust the minimum CPU fan duty cycle. The
values range from 0% to 100%. When the CPU temperature is under the
limit, the CPU fan will operate at the minimum duty cycle.
Chassis Fan 1-4 Q-Fan Control [DC Mode]
[Disabled] Disable the Chassis Q-Fan control feature.
[DC mode] Enable the Chassis Q-Fan control in DC mode for 3-pin chassis fan.
