CPU Fan / Power Fan / Chassis Fan Speed [xxxxRPM] or [Ignored]

The onboard hardware monitor automatically detects and displays the CPU and chassis fan

speeds in rotations per minute (RPM). If the fan is not connected to the motherboard, the field

shows N/A. Select [Ignored] if you do not wish to display the detected speed.

VCORE / 3.3V / 5V / 12V Voltage

The onboard hardware monitor automatically detects the voltage output through the onboard

voltage regulators. Select Ignored if you do not wish to display the detected voltage output.

CPU Q-Fan Function [Enabled]

Allows you to enable or disable the CPU Q-Fan feature that smartly adjusts the fan speeds

for more efficient system operation. Configuration options: [Disabled] [Enabled]

CPU Fan Speed Low Limit [200 RPM]
A warning message will appear to remind you that the CPU fan speed is lower than the

selected value.

Configuration options: [500RPM] [400RPM] [300RPM] [200RPM] [100RPM] [Ignored]
CPU Q-Fan Mode [Silent]
Allows you to set the appropriate performance level of the CPU Q-Fan. When set to

[Standard], the CPU fan automatically adjusts depending on the CPU temperature.

Set this item to [Silent] to minimize fan speed for quiet CPU fan operation, or [Turbo]

to achieve the maximum CPU fan speed. Configuration options: [Turbo] [Standard]

[Silent] [Manual]

The following four items appear only when you set CPU Q-Fan Mode to [Manual].

CPU Upper Temperature [70˚C/158˚F]

Sets the upper limit of the CPU temperature.

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.

Configuration options: [20%] [30%] [40%] [50%] [60%] [70%] [80%] [90%] [100%]
CPU Lower Temperature [20˚C/68˚F]

Displays the lower limit of the CPU temperature.
