Tbh there wasn't one, i just needed to get it all sorted in my head, and properly connected with no bodged connections. I have put a proper 3 pin connector on the hub to connect to the motherboard, can't risk fucking up my £300 motherboard. It's been on now for over an hour with no problem, so i guess its working fine. So there are 48 LEDS connected to the motherboards ARGB connector.
I reckon you could get a ARGB 3 way splitter and just connect Corsair RGB fans to your board that way now i know it works. The only difference would be they would be connected in parallel and not in series as they are using my hub, i'm sure they would still work though.
I am pleased with myself for figuring it out.
