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.
ArchLinux users can try the liquidtux-dkms-gitAUR 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.
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
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.
