CPU Fan Point1 Duty Cycle (%) When the temperature source is lower than the temperature of P1, the fan will operate at the duty cycle of P1. When the temperature source is higher than the temperature of P1, the duty cycle will be determined according to P1-P2 and the temperature source. Use the or keys to adjust the fan/pump duty cycle.

CPU Fan Point1 Duty Cycle (%)
When the temperature source is lower than the temperature of P1, the fan will operate
at the duty cycle of P1. When the temperature source is higher than the temperature
of P1, the duty cycle will be determined according to P1-P2 and the temperature
source. Use the <+> or <-> keys to adjust the fan/pump duty cycle.
Chassis Fan(s) Configuration
Chassis Fan Q-Fan Control
Allows you to set the Chassis Fan operating mode.
[Auto Detect]
Detects the type of installed fan/pump and automatically
switches the control modes.
[DC Mode]
Enables the Q-Fan Control feature in DC mode for 3-pin fan/
pump.
[PWM Mode]
Enables the Q-Fan Control feature in PWM mode for 4-pin fan/
pump.
Chassis Fan Profile
Allows you to set the appropriate performance level of the assigned fan/pump. When
selecting
[Manual]
, we suggest raising your fan/pump duty to 100% if your CPU
temperature exceeds 75
°
C. Please be noted CPU performance will throttle due to
overheating with inefficient fan/pump duty.
Configuration options: [Standard] [Silent] [Turbo] [Full Speed] [Manual]
The following items appear only when
CPU Fan Profile
is set to
[Standard]
,
[Silent]
,
[Turbo]
, or
[Manual].
Chassis Fan Q-Fan Source
The assigned fan/pump will be controlled according to the selected temperature source.
Configuration options: [CPU] [CPU Package] [MotherBoard] [VRM] [Chipset] [T_Sensor]
[Water In T Sensor] [Water Out T Sensor] [Multiple Sources]
For Multiple Sources, select up to three temperature sources and the fan will automatically
change based on the highest temperature.
Chassis Fan Step Up
Step up allows you to adjust how quickly the fan rotation speed
increases, with level 0
being an instantaneous change in speed. The higher the level, the slower the change in
speed, and may also result in less noise, but this will also cause slower heat dissipation.
Configuration options: [Level 0] [Level 1] [Level 2] [Level 3] [Level 4] [Level 5]
Chassis Fan Step Down
Step down allows you to adjust how quickly the fan rotation speed decreases, with level 0
being an instantaneous change in speed. The higher the level, the slower the change in
speed, and may also result in less noise, but this will also cause slower heat dissipation.
Configuration options: [Level 0] [Level 1] [Level 2] [Level 3] [Level 4] [Level 5]
Chassis Fan Speed Low Limit
Allows you to set the lower speed limit for assigned fan/pump. A warning message will
appear when the limit is reached; the warning message will not appear if
[Ignore]
is
selected.
Configuration options: [Ignore] [200 RPM] [300 RPM] [400 RPM] [500 RPM] [600 RPM]
