CPU Q-Fan Control [Auto]
Allows you to set the CPU Q-Fan operating mode.
[Disabled] Disables the CPU Q-Fan control feature.
[Auto] Detects the type of CPU fan installed and automatically switches the mode
control. When a 3-pin CPU fan is installed, select this mode for the DC
mode Q-Fan control.
[DC Mode] Enables the CPU Q-Fan control feature in DC mode for 3-pin CPU fan.
[PWM Mode] Enables the CPU Q-Fan control feature in PWM mode for 4-pin CPU fan.
The following items appear only when you set the CPU Fan Prole to [Manual], [DC Mode]
or [PWM Mode].
CPU Fan Speed Low Limit [300 RPM]
Allows you to disable or set the CPU fan warning speed.
Conguration options: [Ignore] [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] 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 Prole to [Manual].
CPU Upper Temperature [70]
Use the <+> and <-> keys to adjust the upper limit of the CPU temperature. The values
range from 20°C to 75°C.
CPU Fan Max. Duty Cycle (%) [100]
Use the <+> and <-> keys to adjust the maximum CPU fan duty cycle. The values
range from 40% 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 <+> and <-> keys to adjust the maximum CPU fan duty cycle. The values
range from 40% to 100%. When the CPU temperature reaches the upper limit, the
CPU fan will operate at the maximum duty cycle.
CPU Fan Middle. Duty Cycle (%) [20]
Use the <+> and <-> keys to adjust the maximum CPU fan duty cycle. The values
range from 40% 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.
