I have minimal experience with RGB, but I'm planning on a new Ryzen build with an Asus Prime X570-P motherboard, and some Corsair Vengeance RGB ram. Eventually I'd like to replace my existing case fans with some RGB as well, and maybe one day an AIO water cooler with RGB.
1) How do you control RGB colors on the RAM, and potentially case fans down the road? Can any of it be controlled through the UEFI/Bios? or Windows app only? I use an Ubuntu based Linux distro as my OS, no Windows. If Windows only, do you program it once, then you could change your OS (with the understanding the color scheme would be the same)?
2) On another system that I tried RGB fans, that did not have an RGB header on the motherboard, I used a Corsair RGB controller, but could never get the lights on the fans to work properly. Lights were very dull, and wouldn't change colors. I wasn't able to try a different RGB controller, as I didn't have time and logistical access to that system. The fans were Fractal Design, and the fans didn't specify it would work with the Corsair controller ( I learned later there is a fractal design controller, but too late), so I'm assuming they weren't compatible with that controller. Can some fans be picky about what controls them?
