I don't think your bench test is valid to demonstrate Corsair's point 1)most the heat generated in the box (CPU and GC) is going in the water, not in the case. the only heat you are picking up is maybe the RAM, VRM, and PSU... you can check that mesuring a delta temperature between inside and outside the box. 2) from what is shown on the video, 2 radiators stacked one behind the other is what is bugging Corsair. and rightfully so. puting them in series makes rad #2 see all the hot air of rad #1... ending up having 2 rads performing almost the same a 1, (but paying for 2)... what would REALY be efficient, is having them set in parralel. one next to the other both seing fresh air. thats were having 2 rads becomes worth it....
