12Description
13-----------
14
15This driver enables hardware monitoring support for the listed ASUS ROG RYUJIN
16all-in-one CPU liquid coolers. Available sensors are pump, internal and external
17(controller) fan speed in RPM, their duties in PWM, as well as coolant temperature.
18
19Attaching external fans to the controller is optional and allows them to be
20controlled from the device. If not connected, the fan-related sensors will
21report zeroes. The controller is a separate hardware unit that comes bundled
22with the AIO and connects to it to allow fan control.
23
24The addressable LCD screen is not supported in this driver and should
25be controlled through userspace tools.

31supports hot swapping.
