A standard airbased heatsink has a lot more surface area than most waterblocks.
On finned surfaces it's not just about surface area. Air-cooled fins are designed with the cooling properties of air in mind - they typically need much higher surface areas because solid to air heat transfer is so slow. Solid to water on the other hand is much faster, so the surface area requirements are much less - this is how waterblocks manage to have so little.

Having too much surface area won't help, but it shouldn't hinder the effectiveness of the block much either.
It is by coffee alone I set my mind in motion...
