OpenRGB is a free and open source application to control RGB lighting for a multitude of devices, independent of the manufacturer.
It's working on my Manjaro Linux using the AppImage executable. It was not detecting my USB devices though until I ran it with admin privileges. So the keyboard is working fine, but does seem I may have to patch the kernel for the fans and CPU coolers to work.

If you're on Windows, you can give Artemis a try. Open source frontend for OpenRGB. I believe it's still in development, but mostly works to create some fancy RGB scenes.
Yes, sorry I have Brave Browser's Speedreader active, so I just see text when I visit pages.
