Description

This driver enables hardware monitoring support for the listed ASUS ROG RYUJIN all-in-one CPU liquid coolers. Available sensors are pump, internal and external (controller) fan speed in RPM, their duties in PWM, as well as coolant temperature.

The RYUJIN II includes a separate external fan controller. Attaching fans to the controller is optional and allows them to be controlled from the device. If not connected, the controller-related sensors will report zeroes. The RYUJIN III does not expose these controller channels.

The addressable LCD screen is not supported in this driver and should be controlled through userspace tools.

Usage notes

As these are USB HIDs, the driver can be loaded automatically by the kernel and supports hot swapping.
