They aren't. They are a good 15 - 20 degrees lower on water, compared to the original stock cooler. This is on a skinny 240 rad and low speed fans - don't have the space for a full fat radiator in the roof of the case, although I could squeeze in a skinny 360 (already on my list of things to do). 560 GPUs run cooler than those in the 295 anyway. Yes, as I already mentioned, the spot cooling gains were marginal (a couple of degrees) with the fan flow reversed, and resulted in higher chassis ambient temp.
