Fan Speed Control
CPU Q-Fan Control [Disabled]
Allows you to enable or disable the CPU fan controller.
[Disabled] Disables the CPU Q-fan controller.
[Enabled] Enables the CPU Q-fan controller.
The following three items appear when you enable the CPU Fan Control feature.
CPU Fan Speed Low Limit [600 RPM]
Allows you to set the low speed limit of the CPU fan and the system sends warning
message when the fan speed drops below the set value.
Conguration options: [Ignored] [200 RPM] [300 RPM] [400 RPM] [500 RPM]
[600 RPM]
CPU Fan Profile [Standard]
Allows you to set the appropriate performance level of the CPU fan.
[Standard] Sets to [Standard] to make the chassis fan automatically adjust
depending on the CPU temperature.
[Silent] Sets to [Silent] to minimize the fan speed for quiet CPU fan operation.
[Turbo] Set to [Turbo] to achieve maximum CPU fan speed.
[Manual] Sets to [Manual] to display more items for you to manually adjust the
CPU upper/lower temperature, and CPU fan upper/lower duty cycle.
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 20% to 100%. When the CPU temperature reaches the
upper limit, the CPU fan will operate at the maximum duty cycle.
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 20% to 100%. When the CPU temperature is under
40ºC, the CPU fan will operate at the minimum duty cycle.
