I just installed a new NVMe boot drive and fresh install of Windows on it, installed all my programs and games, rebooted, everything's fine, started setting up iCue to adjust RGB settings on my Fans, RAM, Case, and AIO Cooler, noticed that the motherboard was doing this weird RGB chasing that looked kind of cool so I figured I would keep that, I didn't remember it doing this mode before so I figured it must have been part of the latest BIOS update I did before the clean install of Windows. Which is why I just set it to white so it's neutral because if I pick similar colours to the iCue software, they don't chase at the same rate, but setting everything up fresh with a new clean install of Windows, I wanted to change it up. Long story short, I always had my motherboard set to white and the fans and AIO are controlled with Corsair iCue, however I can't control the motherboard RGB with iCue. I have a Gigabyte Aorus Xtreme Z390, paid like $850 after tax for this motherboard, and the RGB software is absolutely garbage, can't say I'm not disappointed by this lol.
