masked, I tend to disagree, and this is purly speculation.

But I would think that the heat would shoot up the pins. Less mass = less resistance. But I would conesntrate, and do the numbers, on a smaller block with less pins. If I had the know how, I would find out the what the heat load on a certain amount of copper is. Then build the block around the numbers. Targeting a copper slug in a non heat cunductive base plate. So that the heat is targeted to the highest volume of water, and not spread out thrue out the block. Its my opinion that this is why some of the acrylic german blocks work as wll as they do. All the heat is concentrated in a copper slug that is large enought to absorb the heat fast enought, but yet small enought to allow the coolant passing over it to effectivly remove the heat
