NZXT Cam Software and OSX support

[MilkIt]

I actually just swapped out my case from Phanteks Enthoo ITX to the new NZXT H200i. The NZXT is very pretty in white and the case is very easy to work in. However the smart hub where fans and the builtin LED is connected to is useless. The fans connected to the smart hub spin up to max. I had to pull them out and plug them into the motherboard directly via splitter. I wish NZXT would port the CAM software even if just a basic version for fan speed and LED color.

Just built a new Hack in an NZXT H700i. Would love CAM support!

I would like to buy that case and a kraken CPU cooler, but guessing will run into problems??

I have a corsair H80i. I just plug the fans into the motherboard CPU fan headers and control everything from BIOS. Works great. That said, led colour doesn't interest me

So doing some digging into this...

There is this tool -> https://github.com/jonasmalacofilho/liquidctl

Somebody has written a GUI for it -> https://gitlab.com/leinardi/gkraken

Of course this is all Linux and not macOS but it shows that it is possible to control these outside of Windows and CAM.

liquidctl its self is Python and will detect the cooler...

censored:~ censored$ liquidctl list
Device 0, NZXT Kraken X (X42, X52, X62 or X72) at bus:address 20:3

However it will not poll it for status...

censored:~ censored$ liquidctl status
NZXT Kraken X (X42, X52, X62 or X72), device 0

usb.core.USBError: [Errno 13] Access denied (insufficient permissions)

Some more digging finds it is a permission error with the usb.core, libusb and PyUSB

Linux users fixed that by modifying udev rules but I can't find the mac side of that... so I suppose I'm stuck now until somebody smarter than me can pick this up

I wrote a small tool to help change it without the need of python, you can check it here: https://github.com/gabrielrinaldi/CAM

Feedback and PRs are welcome!

Care to give any info on HOW to install/run it?

You can download the app here: https://github.com/gabrielrinaldi/CAM/releases/tag/0.0.1

I don't usually write Mac apps, so this is new to me also. If you have Xcode you can also build it using it (then you should download the source code instead).

Thanks... seems like a nice simple menu tool.
Only thing i'd suggest (if possible) is next to the Fan and Pump speed... show the % already selected for each.
One other thing.... what is the temperature sensor being used? Is the temp from the Kraken sensor?

I haven't figure out how to read that yet

Is the temp from the Kraken sensor?

I think its water temperature, its coming from the Kraken, so not from the board.

Thanks! I downloaded it and I can adjust the speed – but the cooler (Kraken X62) always jumps back to full speed after 10 seconds. Is there a fix for this?
