I was going to post the same. Why do people even bother having a whole discussion and interest in a new heatsink, when it's just a rehash or what has already existed for more than a decade and any possible gains in efficiency are overwhelmingly likely to be within the 5% margin at most?These coolers all look the same, as typically cool the same. I think the limit has been reached for this design. A case of reinventing the wheel in my opinion. Improvements can be made by making the cooler even taller and wider, but this isn't feasible due to weight and size restrictions.
