Chapter 3
CPU Temperature / MB Temperature [xxx�C/xxx�F] [xxx�C/xxx�F]
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]
Chassis Fan 1/2/3/4 Speed [xxxx RPM] or [Ignore] / [N/A]
CPU OPT Fan Speed [xxxx RPM] or [Ignore] / [N/A]
The onboard hardware monitor automatically detects and displays the CPU, chassis, power, power,
and assistant fan speed in rotations per minute (RPM). If the fan is not connected to the tant fan speed in rotations per minute (RPM). If the fan is not connected to the
motherboard, the field shows N/A . Select Ignore if you do not wish to display the detected
speed.
CPU Q-Fan Control [Enabled]
[Disabled] Disables the CPU Q-Fan control feature.
[Enabled] Enables the CPU Q-Fan control feature.
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 Profile to [Manual].
CPU Upper Temperature [70]
Use the <+> and <-> keys to adjust the upper limit of the CPU temperature. The values range
from 20ºC to 75ºC.
CPU Lower Temperature [20]
Use the <+> and <-> keys to adjust the lower limit of the CPU temperature. The values range
from 20ºC to 75ºC.
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.
CPU Fan Min. Duty Cycle(%) [20]
Use the <+> and <-> keys to adjust the minimum CPU fan duty cycle. The values range from 0% minimum CPU fan duty cycle. The values range from 0% The values range from 0%
to 100%. When the CPU temperature is under 40ºC, the CPU fan will operate at the minimum When the CPU temperature is under 40ºC, the CPU fan will operate at the minimum
duty cycle.
