Nice design Gabe, though I find it a bit big. I know it's meant for active cooling as well, but one of the things I really like about the DDC's is their size. They fit in very small spaces, and I think in some places such a heatsink prevents placement. Still a great design nonetheless, and I like its design better than Koolance's (sorry Tim, it's just a matter of preference ).

I can't wait to see how well it does in Martin's decoupling test .
