3 Chapter

The following items appear only when you set the CPU Q-Fan Control item to [Auto], [PWM mode] or [DC mode].

CPU Fan Speed Low Limit [200 RPM]

Allows you to set the low limit warning for CPU Fan speed. Configuration options: [Ignore] [100 RPM] [200 RPM] [300 RPM] [400 RPM] [500 RPM]

CPU Fan Profile [Standard]

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 detailed fan speed control parameters.

The following four items appear only when you set 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 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 upper limit, the CPU fan operates at the maximum 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 40ºC, the CPU fan operates at the minimum duty cycle.

Chassis Fan 1/2 Q-Fan Control [DC Mode]

[PWM mode]

Enables the chassis Q-Fan control in PWM mode for 4-pin chassis fan.

[DC mode]

Enables the chassis Q-Fan control in DC mode for 3-pin chassis fan.

[Disabled]

Disables the chassis Q-Fan control feature.

The following items appear only when you set the Chassis Fan 1/2 Q-Fan Control item to [PWM mode] or [DC mode].
