CPU Fan Middle. Duty Cycle (%) [20]
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 [20]
Use the <+> or <-> keys to adjust the lower limit of the CPU temperature.
The values range from 20 to 75. The CPU fan will operate at the minimum
duty cycle when the temperature is lower than the limit.
CPU Fan Min. Duty Cycle(%) [20]
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 the
limit, the CPU fan will operate at the minimum duty cycle.
Disable the Chassis Q-Fan control feature.
Enable the Chassis Q-Fan control in DC mode for 3-pin chassis fan.
Enable the Chassis Q-Fan control in PWM mode for 4-pin chassis fan.
Sets to [Standard] to make the chassis fan automatically adjust
depending on the chassis temperature.
Sets to [Silent] to minimize the fan speed for quiet chassis fan
operation.
Sets to [Turbo] to achieve maximum chassis fan speed.
Sets to [Manual] to assign detailed fan speed control parameters.
