Do you need a RGB header for that? My son's mobo doesn't have one
Right. I think i've used bit less than 2 metres of that sleeve for what i've got in my 011 dynamic.
So to get it all working i used following:
2m Sleeve - 12.49£
2m 100led/m WS2812b 5050 strip - 11.31£
Arduino leonardo micro with corsair lighting protocol (NodePro Scale) firmware plus bits and bobs ( wires, connectors) ( info about Corsair lighting protocol can be found on Github) - 7-10£
All controlled by iCue as device recognised as NodePro
Total - around 33-35£
It worked out cheaper than Phanteks can offer, and it's a snug fit (literally at the bottom fans are holding it in place tight)
