airgoo Magnetic 8-Port ARGB Controller, Compact SATA Powered ARGB PC Lighting Hub, Easy Install for Mini & Mid-Tower Cases, Compatible with SignalRGB & OpenRGB, AG-DRGB08

Have set up just 1 device for that header, and not multiple? For example, on a single argb header, it can only do one device config(everything is copied to the rest of the chain). One header cannot be setup to control multiple devices, it just uses the same signal for everything in the chain. If want multiple device control per device, could do the aio on one argb header, and the others on another header, or could pick up a compatible ARGB hub with individual addressing that can setup in signal RGB. This one has 8 ports (there's also a 16 port/device one as well) https://www.amazon.com/dp/B0GTYZCSHZ
