Allow Fan Stop [Disabled]
This item allows the fan to run at 0% duty cycle when the temperature of the source is
dropped below the lower temperature.
Conguration options: [Disabled] [Enabled]
Water Pump Control [Disabled]
[Disabled] Disable the Water Pump control feature.
[DC Mode] Enable the Water Pump control in DC mode for 3‑pin chassis fan.
[PWM Mode] Enable the Water Pump control in PWM mode for 4‑pin chassis fan.
The following items appear only when you set the Water Pump Control to [DC mode] or
[PWM Mode].
Water Pump Upper Temperature [70]
Use the <+> or <‑> keys to adjust the upper limit of the water pump temperature.
The values range from 25 to 75.
Water Pump Max. Duty Cycle (%) [100]
Use the <+> or <‑> keys to adjust the maximum water pump duty cycle. The values
range from 20% to 100%. When the CPU temperature reaches the water pump
upper temperature limit, the water pump will operate at the maximum duty cycle.
Water Pump Middle Temperature [25]
Use the <+> or <‑> keys to adjust the middle limit of the water pump temperature.
The values range from 20 to 75.
Water Pump Middle Duty Cycle (%) [20]
Use the <+> or <‑> keys to adjust the middle water pump duty cycle. The values
range from 20% to 100%. When the CPU temperature reaches the water pump
middle temperature limit, the water pump will operate at the middle duty cycle.
Water Pump Lower Temperature [20]
Use the <+> or <‑> keys to adjust the lower limit of the water pump temperature.
The values range from 0 to 75. The water pump will operate at the minimum duty
cycle when the temperature is lower than the limit.
Water Pump Min. Duty Cycle(%) [20]
Use the <+> or <‑> keys to adjust the minimum water pump duty cycle. The values
range from 20% to 100%. When the CPU temperature is under the limit, the water
pump will operate at the minimum duty cycle.
