Chapter 3
CPU Q-Fan Mode [Optimal]
[Performance] Sets to [Performance] to achieve maximum CPU fan speed.
[Optimal] Sets to [Optimal] to make the CPU fan automatically adjust depending on
the CPU temperature.
[Silent] Sets to [Silent] to minimize the fan speed for quiet CPU fan operation.]
[Manual] Sets to [Manual] to assign detailed fan speed control parameters.
The following four items appear only when you set CPU Q-Fan Mode to [Manual].
CPU Upper Temperature [70ºC/158ºF]
Sets the upper limit of the CPU temperature.
Conguration options: [30ºC/86ºF] [40ºC/104ºF] [50ºC/122ºF] [60ºC/140ºF]
[70ºC/158ºF] [80ºC/176ºF] [90ºC/194ºF]
CPU Fan Max. Duty Cycle [100%]
Sets the maximum CPU fan duty cycle. When the CPU temperature reaches the upper
limit, the CPU fan will operate at the maximum duty cycle.
Conguration options: [20%] [30%] [40%] [50%] [60%] [70%] [80%] [90%] [100%]
CPU Lower Temperature [20ºC/68ºF]
Displays the lower limit of the CPU temperature.
CPU Fan Min. Duty Cycle [20%]
Sets the minimum CPU fan duty cycle. When the CPU temperature is under 20ºC/68ºF,
the CPU fan will operate at the minimum duty cycle.
Conguration options: [00%] [10%] [20%] [30%] [40%] [50%] [60%] [70%] [80%] [90%]
[100%]

[Disabled] Disables the Chassis Q-Fan control feature.
[Enabled] Enables the Chassis Q-Fan control feature.
The following item appears only when you set Chassis Q-Fan Mode to [Enabled].
Chassis Fan Speed Low Limit [200 RPM]
A warning message will appear to remind you that the chassis fan speed is lower than the
selected value.
Conguration options: [500RPM] [400RPM] [300RPM] [200RPM] [100RPM] [Ignored]
Chassis Q-Fan Mode [Silent]
[Performance] Sets to [Performance] to achieve maximum chassis fan speed.
[Optimal] Sets to [Optimal] to make the chassis fan automatically adjust depending
on the chassis temperature.
[Silent] Sets to [Silent] to minimize fan speed for quiet chassis fan operation.
[Manual] Sets to [Manual] to assign detailed fan speed control parameters.
