Good afternoon.
I am doing my first watercooling setup and have decided on a dual loop.

I've got dual D5 pump/res combo's but am at an absolute loss on how to get it all connected.
So, to start with, it comes with a LED ring which has an 'IN' and OUT' 4 pin connector.
On the actual D5, their is a USB (5 pin), BUS (4 pin), FAN and Sata connector.

Right now, I'm just setting up the case, I've not actually got the coolant or set up any tubes, but I would like to get all the LED stuff tested, but I honestly do not know where to start.
Firstly, do I need the pump to be connected to the sata to power the whole thing? If so, It says not to power the pump without coolant, so I have no way of testing it yet.
Secondly, I have two controllers in my PC, so both USB ports on the motherboard are occupied.

I've read and re-read the instruction booklet, but in my uneducated opinion, it seems really bad.

One thing I've found is I could buy this adapter: https://www.aquatuning.co.uk/cables/argb…nection?c=23278
Which would then make some of the wires fit into my razer controller, so maybe that is a solution, but really, any guidance would be much appreciated.

Thank you
