I just hooked it up. I have not done any testing or playing with the settings yet. Here is a down and dirty no-audio video showing the different screens/menus. I've connected the shut-down wire to the mobo power header. Those two wires are very thin and separate. It would have been nice if they were bonded together for the sake of cable management, but otherwise it seems like a very well-made product. It was nice to see all of my 12V lines were well balanced right off the bat. The thermal sensor connected to the motherboard T-sensor that I have inserted between the wires next to the connector shows the same temperature reading as the WireView Pro II, so that is also good.
I had to add a 25mm G1/4 extension on the GPU water out fitting to raise it up enough to clear the top of the WireView Pro II.
I am not sure what an acceptable variance is between pins, but my impression is this is close enough to not be an issue. If there was over 1-2A difference between pins that might be a concern. This was running a 4K MSI Kombustor benchmark with the GPU at all default clocks and voltage. Idle power is around 48-50W.
