NZXT Kraken 2023 AIO CPU Cooler Monitoring With Linux 6.10

([Hardware] 3 Hours Ago NZXT-Kraken All In One Coolers)


Merged back in 2021 with Linux 5.13 was [1]an NZXT Kraken hardware monitoring "HWMON" driver to support sensor monitoring of these all-in-one liquid cooling products from NZXT. Over time [2]more NZXT Kraken AIO coolers have been supported by the Linux kernel and with the upcoming Linux 6.10 kernel the latest NZXT Kraken CPU coolers will be supported.

For Linux 6.10 the NZXT Kraken 2023 (standard) and NZXT Kraken 2023 Elite all-in-one CPU coolers will be supported by the existing "nzxt-kraken3" driver. These newer NZXT Kraken product revisions are very similar to older models except for differences in the fan curve setting.

The NZXT-Kraken3 driver allows for monitoring the liquid temperature and pump speed as well as PWM control. There is also support for exposing to the Linux user-space the connected fan speed and duty along with PWM controls. The NZXT Kraken kernel driver doesn't directly deal with the RGB LEDs or LCD screen on some of the Kraken models but that's left to user-space software like [3]liquidctl for manipulating.

The NZXT Kraken 2023 cooler support is queued in [4]this patch via the hardware monitoring subsystem's "hwmon-next" branch ahead of the Linux 6.10 merge window.

"We invented a new protocol and called it Kermit, after Kermit the Frog,
star of "The Muppet Show." [3]

[3] Why? Mostly because there was a Muppets calendar on the wall when we
were trying to think of a name, and Kermit is a pleasant, unassuming sort of
character. But since we weren't sure whether it was OK to name our protocol
after this popular television and movie star, we pretended that KERMIT was an
acronym; unfortunately, we could never find a good set of words to go with the
letters, as readers of some of our early source code can attest. Later, while
looking through a name book for his forthcoming baby, Bill Catchings noticed
that "Kermit" was a Celtic word for "free", which is what all Kermit programs
should be, and words to this effect replaced the strained acronyms in our
source code (Bill's baby turned out to be a girl, so he had to name her Becky
instead). When BYTE Magazine was preparing our 1984 Kermit article for
publication, they suggested we contact Henson Associates Inc. for permission
to say that we did indeed name the protocol after Kermit the Frog. Permission
was kindly granted, and now the real story can be told. I resisted the
temptation, however, to call the present work "Kermit the Book."
