Well, is is surprising if you ask me. First of all I cannot explain that difference, which, from my point of view is absolutely huge. Second, this kind of design was very poorly implemented untill now, and I didn't expect too much of it at high rpm. It seems that the 6 heatpipes and the Noctua touch really added something to this beast. Anyway, this is just a sneak peak, we will know the exact situation after all tests are done and re-done.
