Like I said before, you can only get so much flow and fin area at a given noise level, and that limits performance. To increase performance, you have to increase the fin area, and the only way to increase fin area without increasing noise is to make the fin density go down so you can use quieter fans, making form factor size go up.
I think this rad is taking Thermochill's thick rad, low fin density to a whole new extreme. Low fin density, but huge fins in an even bigger form factor. Even more performance for those who need it quiet, in a slightly larger form factor.
