| 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`_). | |

| Usage Notes | |
| ----------- | |
| As these are USB HIDs, the driver can be loaded automatically by the kernel and | |
| supports hot swapping. | |
