- Kernel driver nzxt-kraken2
- ==========================
- Supported devices:
- * NZXT Kraken X42
- * NZXT Kraken X52
- * NZXT Kraken X62
- * NZXT Kraken X72
- Author: Jonas Malaco
- Description
- -----------
- This driver enables hardware monitoring support for NZXT Kraken X42/X52/X62/X72
- all-in-one CPU liquid coolers. Three sensors are available: fan speed, pump
- speed and coolant temperature.
- Fan and pump control, while supported by the firmware, are not currently
- exposed. The addressable RGB LEDs, present in the integrated CPU water block
- and pump head, are not supported either. But both features can be found in
- existing user-space tools (e.g. `liquidctl`_).
- .. _liquidctl: https://github.com/liquidctl/liquidctl
- Usage Notes
- -----------
- As these are USB HIDs, the driver can be loaded automatically by the kernel and
- supports hot swapping.
