This driver enables hardware monitoring support for NZXT Kraken X53/X63/X73 and Z53/Z63/Z73 all-in-one CPU liquid coolers. All models expose liquid temperature and pump speed (in RPM), as well as PWM control (natively only through a temp-PWM curve, but the driver also emulates fixed PWM control on top of that). The Z-series models additionally expose the speed and duty of an optionally connected fan, with the same PWM control capabilities. Pump and fan duty control mode can be set through pwm[1-2]_enable, where 1 is for the manual control mode and 2 is for the liquid temp to PWM curve mode. Writing a 0 disables control of the channel through the driver after setting its duty to 100%. As it is not possible to query the device for the active mode, the driver keeps track of it. The temperature of the curves relates to the fixed [20-59] C range, per device limitations, and correlating to the detected liquid temperature. Only PWM values (ranging from 0-255) can be set. The addressable RGB LEDs and LCD screen, included only on Z-series models, are not supported in this driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
