If cooling was the concern, the shroud should be attached to heat pipes that help cool the caps, SB and other hot running areas of the board. With the surface area the shroud has, the cooling capability is tremendous, unfortunately, it seems poorly executed.
Though I doubt the cooling capability of the design, it sure does look great! Hopefully they release a similar model for AMD boards. I don't mind spending additional coin for aesthetics, but all the empty promises of the marketing campaigns get a little tedious. Tell it how it is: It costs more because we think it's pretty, any improvements to performance or thermal characteristics are accidental and a byproduct of manufacturing.
