| 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. |
