2.7.4 Q-Fan Conguration
The subitems in this menu allows you to congure the Q‑Fan features.
Q-Fan Tuning
Click [OK] button to detect the lowest speed and congure the minimum duty circle for each
fan. Do not shut down or reset your system during the tuning progress. Conguration options:
[Ok] [Cancel]
CPU Q-Fan Control [PWM Mode]
[Disabled] Disables the CPU Q‑Fan control feature.
[PWM Mode] Enable the CPU Q‑Fan control in PWM mode for the 4‑pin CPU fan.
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. Conguration options: [Ignore] [200RPM] [300
RPM] [400 RPM] [500 RPM] [600RPM]
CPU Fan Prole [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 Prole 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 [25]
Use the <+> or <‑> keys to set the value for CPU Middle Temperature. The range of
the values depends on the CPU installed.
CPU Fan Middle Duty Cycle(%) [20]
Use the <+> or <‑> keys to adjust the CPU fan middle duty cycle. The values range
from 20% to 100%. When the CPU temperature reaches the upper limit, the CPU fan
operates at the maximum duty cycle.
CPU Lower Temperature [20]
Use the <+> or <‑> keys to adjust the CPU fan’s lower temperature. The values range
from 0°C to 75°C.
