Linux kernel hwmon drivers for AIO liquid coolers and other devices

The goal of this project is to offer hwmon drivers for closed-loop liquid coolers and other devices supported by liquidctl, making their sensor data available in /sys/class/hwmon/hwmon*.

By using the standard hwmon sysfs interface, sensors, tools using libsensors, as well as programs that read directly from the raw sysfs interface can access these devices' sensors. For more information, read the documentation of the hwmon sysfs interface and check the lm-sensors repository.

Installing with DKMS

ArchLinux users can try the liquidtux-dkms-git^AUR package. After the package is installed, manually load the desired drivers.

# modprobe krx62  # Kraken X42, X52, X62, X72
# modprobe grdp3  # Smart Device (V1)

Those on other distros can experiment with directly using the dkms.conf in that package. It should work with minimal modifications.

Manually building, inserting and installing

The drivers should be built with the kbuild system.

A simple Makefile is provided that simplifies this in normal scenarios. The built modules can then be loaded with insmod.

$ make
# insmod krx62.ko  # Kraken X42, X52, X62, X72
# insmod grdp3.ko  # Smart Device (V1)

To unload them, use rmmod or modprobe -r.

If testing was successful the modules can be installed to the system with the modules_install target:

# make modules_install

Device support

This is the current state of the out-of-tree drivers.

Device	State	device driver	hwmon driver
NZXT Kraken X42, X52, X62, X72	hackish but using 24/7	krx62	krakenx
NZXT Smart Device (V1)	hackish but using 24/7	grdp3	smart_device

Once the drivers are mature they will be proposed to upstream.
