This driver is a heavily rewritten fork based on https://github.com/jaksi/leviathan.
Linux device driver that supports controlling and monitoring NZXT Kraken water coolers.
NZXT is NOT involved in this project, do NOT contact them if your device is damaged while using this software.
Also, while it doesn't seem like the hardware could be damaged by silly USB messages (apart from overheating), I do NOT take any responsibility for any damage done.
- NZXT Kraken X52 (Vendor/Product ID:
1e71:170e) (Only for controlling the fan/pump speed, and monitoring the pump and fan rpm and liquid temperature. I did not bother with control of RGB)
make
make updateThe driver implements the standard hwmon interface.
You can find the correct hwmon index:
grep kraken /sys/class/hwmon/hwmon*/nameThe numbered hwmon (for example, hwmon2) is should be used for the DEVICE placeholders below.
The USB HID driver may sieze control of the cooler, because the cooler is implemented as a "hiddev", which are non-human-interface human-interface-devices. You can't make this stuff up.
| File | Purpose | Access |
|---|---|---|
| pwm1 | Pump throttle | RW |
| pwm2 | Fan throttle | RW |
| pwm1_enable | 0=full, 1=manual, 2+=auto (Pump) | RW |
| pwm2_enable | 0=full, 1=manual, 2+=auto (Fan) | RW |
| fan1_input | Pump RPM | RO |
| fan2_input | Fan RPM | RO |
| temp1_input | Liquid temperature | RO |
| name | "kraken" | RO |
The default behaviour is to have 2 in both _enable files, resulting in automatic speed control by default. If you want to override the automatic control, write 1 to the appropriate _enable file from the table above.
The values for the pwmN files are 0 to 255, corresponding to 0% to 100%.
The values for the fanN_input files are in RPM.
The temp1_input file is in 1/1000ths of a degree C (millicentigrade). For example, 30000 is 30C, 35000 is 35C.
Each file has a corresponding _label file from which you can read a reasonably human readable description of the purpose of the corresponding file.
