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 eld
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 efcient system operation. Conguration 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.
Conguration 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. Conguration 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.
Conguration options: [30˚C/86˚F] [40˚C/104˚F] [50˚C/122˚F] [60˚C/140˚F][30˚C/86˚F] [40˚C/104˚F] [50˚C/122˚F] [60˚C/140˚F][40˚C/104˚F] [50˚C/122˚F] [60˚C/140˚F]˚C/104˚F] [50˚C/122˚F] [60˚C/140˚F]C/104˚F] [50˚C/122˚F] [60˚C/140˚F]˚F] [50˚C/122˚F] [60˚C/140˚F]F] [50˚C/122˚F] [60˚C/140˚F]˚C/122˚F] [60˚C/140˚F]C/122˚F] [60˚C/140˚F]˚F] [60˚C/140˚F]F] [60˚C/140˚F]˚C/140˚F]C/140˚F]˚F]F]

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 [20 ˚ C/68 ˚ F]
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 20˚C/68˚F,˚C/68˚F,C/68˚F,˚F,F,
the CPU fan will operate at the minimum duty cycle.
Conguration options: [00%] [10%] [20%] [30%] [40%] [50%] [60%] [70%] [80%] [90%]
