2.7.3 CPU / Chassis Fan Speed [xxxx RPM] / [N/A]
The onboard hardware monitor automatically detects and displays the CPU / chassis fan 1
speeds in rotations per minute (RPM). If the fan is not connected to the motherboard, the
eld shows N/A.
2.7.4 CPU Q-Fan Control [On]
[Off] Disables the CPU Q‑Fan control feature.
[On] Enables the CPU Q‑Fan control feature.
CPU Fan Speed Lower Limit [200 RPM]
This item appears only when you enable the CPU Q-Fan Control feature and allows
you to 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 25ºC 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 Middle Temperature [25ºC]
Use the <+> or <‑> keys to adjust the CPU middle temperature. The values range
from 20ºC to 75ºC.
CPU Fan Middle. Duty Cycle (%) [20]
Use the <+> or <‑> keys to adjust the middle 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 Lower Temperature [20ºC]
Use the <+> and <‑> keys to adjust the lower limit of the CPU temperature. The
values range from 20ºC to 75ºC.
CPU Fan Min. Duty Cycle(%) [20]
Use the <+> or <‑> keys to adjust the minimum CPU fan duty cycle. The values
range from 20% to 100%. When the CPU temperature is under the lower limit of the
CPU temperature, the CPU fan will operate at the minimum duty cycle.
