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: github.com/kryzaach/Lian-Li-Unifan-Sync but think I have it placed in the wrong location, as it errors out immediately.
