Chassis Fan 1/4 Min. Duty Cycle(%) [60]

Use the <+> or <-> keys to adjust the minimum chassis fan duty cycle. The values may differ via Qfan tuning.

EXT 1/3 Q-Fan Control [DC Mode]

These items allow you to set the extension fans’ Q-Fan control feature into DC Mode, PWM Mode, or disable these extension Q-Fan controls from your motherboard.

Configuration options: [Disabled] [DC Mode] [PWM Mode]

The following items appear only when you set the EXT 1/3 Q-Fan Control to [PWM Mode] or [DC Mode].

EXT 1/3 Q-Fan Source [CPU]

This item controls the assigned fan according to the selected temperature source. Configuration options: [CPU] [MB] [VRM] [PCH] [T_SENSOR1] [EXT_SENSOR1] [EXT_SENSOR2] [EXT_SENSOR3]

If you select T_SENSOR1, plug a thermistor cable to T_SENSOR1 header and stick the thermistor cable’s head to the desired component as the temperature source.

[Standard]

Set to make the chassis fan adjust automatically depending on the

 

chassis temperature.

[Silent]

Set to minimize the fan speed for quiet chassis fan operation.

[Turbo]

Set to achieve maximum chassis fan speed.

[Manual]

Set to assign detailed fan speed control parameters.

The following items appear only when you set the EXT Fan Profile to [Manual].

EXT 1/3 Upper Temperature [70]

Use the <+> or <-> keys to adjust the upper limit of the EXT 1/3 temperature. The values range from 40°C to 90°C.

EXT Fan 1/3 Max. Duty Cycle(%) [100]

Use the <+> or <-> keys to adjust the maximum extension fan duty cycle. The values may differ via Qfan tuning.
