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. | |
