When I saw the initial pictures of this 4 pipe version, I couldn't see how they were going to pull off a better heatsink considering that with the 3 pipe version, every pipe comes in full contact with the heatspreader (at least on Intel procs). The staggering wouldn't do anything given the spacing between pipes. Sure enough, the review shows which pipes come in full contact with the heatspreader and which only get half. I'd rather have 3 in full contact where it counts over two. :\ Reduce the spacing between pipes on this 4 pipe version and maybe the outcome would be different. Hopefully the 3 pipe version will remain in one form or another.
