ASUS Ryuo I Liquid Coolers

March 3, 2026 · View on GitHub

Driver API and source code available in liquidctl.driver.asus_ryuo.

New in 1.16.0.

Initialization

Initialization is not required. It outputs the firmware version:

# liquidctl initialize
ASUS Ryuo I 240
└── Firmware version    AURO0-S452-0205

Monitoring

This driver does not report status information (e.g. temperature, fan RPM, or duty cycle).

# liquidctl status
ASUS Ryuo I 240
└── No status available

Speed control

Setting fixed fan speed

Use channel fans or fan to set the speed of all fans connected to the cooler:

# liquidctl set fans speed 60

Only a single fan channel is available. Speeds are set as a fixed percentage (duty cycle) from 0–100%.

Duty to speed relation

The resulting speeds do not scale linearly to the set duty values.
For example duty values below 20% result in no changes in pump speed.

Fan duty values approximately map to the following speeds (± 10%):

Duty (%)Fan speed (rpm)
0810
10810
20810
301110
401380
501590
601830
702070
802250
902430
1002580

Limitations

  • No telemetry (fan speed, liquid temperature, etc.) is currently available.
  • Only fixed fan speed control is supported.
  • The cooler’s screen is not supported.
