| 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. |
