Case/component lighting has been a thing for at least 20 years. 20 years ago it was cold cathode tubes lighting your case. For about the past 10 years RGB lighting has pretty hard to avoid if you wanted to build your own PC.

Wow. Goes to show how long CPUs can stay relevant these days, because it has been about that long since I've built a machine from scratch...

Time makes fools of us all, eh?

Yes, that's a thing now. My 12y nephew just asked for an RGB fan for his birthday... Apparently they're cool

It's not just kids who like RGB lighting. I know a few people in their late 30s and early 40s that love the colorful effects.

Personally I do like lighting, but I want static colors. The great thing about RGB lighting is that I can choose whatever color I want. Much better than when the choices were basically just red or blue and you had to commit to one when you bought it.

That was also my reasoning to go full RGB. I just didn’t know that the RAM default is Rainbow puke. And these things are the hardest to control.

My EKWB AIO is the worst for that. It has standard addressable RGB to control the lighting, but the default when that's not plugged in is to do the rainbow cycling. The default for all disconnected lighting should be no lights!

Or at least some reasonable default. I understand that the device wants to do a show off. I have a gigabyte GPU which I can’t control from my Gigabyte BIOS. It can only control the fans. If I turn off the lights from the BIOS sometimes the GPU also reacts to that. And Sometimes one of the LEDs turns on red. The RAM is uncontrollable except when in windows. So at the moment I boot into windows and then soft reboot into Linux to have all lights turned off. Obviously not what I initially wanted.

But what kills me the most is the fact that the RGB Lightshow from RAM keeps running even when I put the system to sleep!

You could desolder or, if daring enough, cut one of the trace on the pcb that power the LEDs. They would likely have a common power trace.
