Support for these devices is still experimental.
It is necessary to initialize the device once it has been powered on.
# liquidctl initialize
The +12V rails normally function in multiple-rail mode, and initialize will by default reset the PSU to that mode; single-rail mode can be selected by passing --single-12v-ocp to initialize.
Note: changing the +12V OCP mode is currently an experimental feature.
The PSU is able to report monitoring data about its own hardware and basic electrical variables for the input and output sides.

The fan speed is normally controlled automatically by the PSU. It is possible to override this and set the fan to a fixed duty value using the fan channel.
# liquidctl set fan speed 90
This changes the fan control mode to software control and sets the minimum allowed duty value to 30%. To revert back to hardware control, re-initialize the device.
