CPU Temperature / MB Temperature [xxxºC/xxxºF]
The onboard hardware monitor automatically detects and displays the CPU and motherboard
temperatures. Select Ignore if you do not wish to display the detected temperatures.
CPU Fan Speed [xxxx RPM] or [Ignore] / [N/A]
CPU OPT Speed [xxxx RPM] or [Ignore] / [N/A]
Chassis Fan 1/4 Speed [xxxx RPM] or [Ignore] / [N/A]
The onboard hardware monitor automatically detects and displays the CPU, chassis,
and power fan speed in rotations per minute (RPM). If the fan is not connected to the
motherboard, the eld shows N/A. Select Ignore if you do not wish to display the detected
speed.
CPU Voltage, 3.3V Voltage, 5V Voltage, 12V Voltage
The onboard hardware monitor automatically detects the voltage output through the onboard
voltage regulators. Select Ignore if you do not want to detect this item.
CPU Q-Fan Control [Enabled]
[Disabled] Disables the CPU Q-Fan control feature.
[Enabled] Enables the CPU Q-Fan control feature.
CPU Fan Speed Low Limit [600 RPM]

disable or set the CPU fan warning speed.
Conguration options: [Ignore] [200 RPM] [300 RPM] [400 RPM] [500 RPM] [600 RPM]
CPU Fan Profile [Standard]
This item appears only when you enable the CPU Q-Fan Control feature and allows
you to set the appropriate performance level of the CPU fan.
[Standard] Sets to [Standard] 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.
[Turbo] Sets to [Turbo] to achieve maximum CPU fan speed.
[Manual] Sets to [Manual] to assign detailed fan speed control parameters.
The following four items appear only when you set CPU Fan Prole to [Manual].
CPU Upper Temperature [70]
Use the <+> and <-> keys to adjust the upper limit of the CPU temperature. The values range
from 40ºC to 90ºC.
CPU Fan Max. Duty Cycle(%) [100]
Use the <+> and <-> 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.
