A temperature sensor can be connected to it, in which case it provides its reading
and an estimation of the dissipated/absorbed power in the liquid cooling loop.
+The Poweradjust 3 controller exposes a single external temperature sensor.

Depending on the device, not all sysfs and debugfs entries will be available.
Writing to virtual temperature sensors is not currently supported.
