Thank you for the continued effort to help! If I boot into windows and enable the “MB RPM Sync”, the fans are recognized by the BIOS and ramp up and down as needed. This setting does not persist after a shutdown tho. The only way I’ve found to consistently have the fans work as intended after a shutdown is to unplug the USB cable from the Lian Li controller, which kills RGB. I have the PWM connector from the controller going straight into one of the connectors on my mobo. I can tell that after a shutdown, the fans just rotate on their lowest setting, until I open L-Connect 3 again on windows or disconnect the usb port. I’m attempting to implement this: https://github.com/kryzaach/Lian-Li-Unifan-Sync but think I have it placed in the wrong location, as it errors out immediately.
Geeze, that's extremely frustrating... they really switched up the headaches between v1 and v2. I'm sorry I couldn't be more help! Hopefully you can find a software solution to get it going.
I don't mean to repeat troubleshooting you've already done with the python script, apologies in advance if this is stuff you've already done. If it's erroring immediately, you may want to double check that you have pyUSB in place and UDEV rules to get access to the device if you're not running the script as root.
edit: You may also need to check that your Vendor ID and Product ID match what the script was written for, given that there seem to be some different iterations of Lian Li's hardware just in general.
Thank you so much for continuing to try and help. It’s greatly appreciated. I am very new to Linux so while I can do some basics, this is very helpful. I installed pyUSB but still get an error when running the script. I have the script placed in my home folder. Should it be elsewhere? The error I get is “No module named ‘usb’. I did adjust the script to have my controller’s proper identification so feels like I’m missing a small piece of the puzzle!
I'm not familiar with Nobara, but I can at least show how I would install pyUSB for use in Debian:
If you follow the instructions exactly as in the readme, it will error:
Instead, I would create a virtual environment (I'm using virtualenv instead of venv)
Then activate the environment and run the install with pip
Without the actual hub, that's as far as I can go I think - but maybe this will help give you some options and documentation to explore!
Thank you. This is great info. I will give this a shot when I can.
