Hello everyone!
I finally got everything setup with the controller and all fans are working and show up on the software, however, they do not change color completely on the back part of the fan and it stays a certain color, the ones connected to the first controller stay red, while the ones connected to the second controller stay blue, no matter which color I choose. It only gets rid of that color when using default rainbow RGB. Pictures attached. In both examples I was trying to make the color all green, and selected green only in the software (also tried with Razer synapse, no luck). But as you can see, the blue/red back LED does not change color.
