Fan/pump speed control on Linux for NZXT Kraken x62

Unmaintained

This repository is unmaintained as I do not own a Kraken anymore. If this doesn't work for you or it doesn't fulfill your needs, it's best to look for other forks or solutions. though I may still answer questions.

Fan/pump speed control on Linux for NZXT Kraken X62 (possibly other editions)

DISCLAIMER

Use at your own risk, I take NO responsibility if anything crazy happens. Neither does NZXT as they are not involved.

With that said however, this is basic stuff - nothing crazy has happened in my testing, and I can't think of a reason why anything bad could happen.

camctl's Issues

Depencency missing: cam

Using Ubuntu 20.04 I am missing cam as dependency:

Traceback (most recent call last):
  File "/usr/bin/camctl", line 56, in <module>
    cam = CAM(vid, pid)
  File "/usr/bin/camctl", line 12, in __init__
    self._find()
  File "/usr/bin/camctl", line 16, in _find
    self.device = devices[0]
IndexError: list index out of range

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/camctl", line 64, in <module>
    cam.declaim()
NameError: name 'cam' is not defined

a sudo python3 -m pip install cam does not seem to install the right cam/does not solve the issue. What is cam?

Does it will be work on macOS/bsd?

Hi, thanks for your tool!

I want to build a hack and use the nzxt cooler.

Does it will be work? Otherwise I will check it soon.

Question

Hi, I bought a Kraken x62 for my next build and i was wondering if it is possible to control radiator fans with this tool if I connect them to the fan splitter included on the kraken kit or if instead I would have to connect radiator fans to my motherboard. Also I want to thank you for creating this tool as Linux support is very important for me. (Sorry for my bad english).

Question regarding fan and pump speed?

Does this just set the starting point of the fan and pump? Will they still ramp up in speed as the temperature does?

Header Bits

Hi, Just curious as I've never written a USB Driver before - how did you figure out which bits were for what, and the possible range of values? Thanks
def fan(self, speed):
print('Setting fan speed to {}..'.format(speed))
self.device.write(1, [2, 77, 0, 0, speed, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0])

def pump(self, speed):
	print('Setting pump speed to {}..'.format(speed))
	self.device.write(1, [2, 77, 64, 0, speed, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0])

Error on Ubuntu 16.04

After the installation, when I try to type
sudo camctl --help
I get the following error:

Traceback (most recent call last): File "/usr/bin/camctl", line 3, in <module> import usb.core ImportError: No module named 'usb'
Any ideas? :D
