15Description
16-----------
17
18This driver enables hardware monitoring support for NZXT Kraken X42/X52/X62/X72
19all-in-one CPU liquid coolers.  Three sensors are available: fan speed, pump
20speed and coolant temperature.
21
22Fan and pump control, while supported by the firmware, are not currently
23exposed.  The addressable RGB LEDs, present in the integrated CPU water block
24and pump head, are not supported either.  But both features can be found in
25existing user-space tools (e.g. `liquidctl`_).

29Usage Notes
30-----------

32As these are USB HIDs, the driver can be loaded automatically by the kernel and
33supports hot swapping.
