Hey all, I posted previously on this, just wanted to share and update.
Like many others, I grabbed a NZXT internal usb hub.
I have largely resolved the Commander Pro and attached AIO disconnects I was experiencing. For a few days now the hub has happily run the Commander and my H100i RGB without issue.
I will note that i was initially getting a usb ding when i'd poke the usb hub around.... but that's stopped, and at this stage, as long as things keep working, I don't wont to force a loose connection from the hub, commander or aio to come out of hiding.
Big point, and this ties in with my only apprehension with NZXT design
This is all running fine without the hub power plugged in!
Since everything connected has it's own Sata power, I was loath to put a whole molex cable into my modern day build. So I thought i'd try it without the molex power for the hub connected. And it all works, all the lights, the pump, fans etc, all in iCue, all happy.
So if you are thinking of the NZXT hub, and don't want to mess with your epic cable management, or ordering an addition sata->4pin addaptor, you don't actually need to worry ;)
