Fan Speed Control
CPU Q-Fan Control [Auto]
[Auto] Detect the type of CPU fan installed and automatically switch the control
modes.
[DC Mode] Enable the CPU Q-Fan control in DC mode for 3-pin CPU fan.
[PWM Mode] Enable the CPU Q-Fan control in PWM mode for 4-pin CPU fan.
The following items appear only when you set the CPU Q-Fan Control to [Auto].
CPU Fan Speed Lower Limit [300 RPM]
This item allows you to set the low limit warning for CPU Fan speed.
Conguration options: [Ignore] [200 RPM] [300 RPM] [400 RPM] [500 RPM] [600 RPM]
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 Prole to [Manual].
CPU Upper Temperature [70]
Use the <+> or <-> 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 <+> 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 [45]
Displays the lower limit of the CPU temperature.
CPU Fan Middle. Duty Cycle (%) [60]
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 Lower Temperature [40]
Displays the lower limit of the CPU temperature.
CPU Fan Min. Duty Cycle(%) [60]
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 40ºC,
the CPU fan will operate at the minimum duty cycle.
