| 15 | Description | |
| 16 | ----------- | |
| 17 | ||
| 18 | This driver enables hardware monitoring support for NZXT Kraken X42/X52/X62/X72 | |
| 19 | all-in-one CPU liquid coolers. Three sensors are available: fan speed, pump | |
| 20 | speed and coolant temperature. | |
| 21 | ||
| 22 | Fan and pump control, while supported by the firmware, are not currently | |
| 23 | exposed. The addressable RGB LEDs, present in the integrated CPU water block | |
| 24 | and pump head, are not supported either. But both features can be found in | |
| 25 | existing user-space tools (e.g. `liquidctl`_). | |

| 29 | Usage Notes | |
| 30 | ----------- | |
| 31 | ||
| 32 | As these are USB HIDs, the driver can be loaded automatically by the kernel and | |
| 33 | supports hot swapping. | |
