[Amps] Force cooled heatsink aerodynamics

I have one of these heatsinks that have two 120 mm side by side and it is
with the air flow chamber.
The chamber is just an empty box about the thickness of the fans, in my case
perhaps 35-40 mm.
How exactly this helps I can only intuitively imagine, I would think that
having fan blades rotating very close to a dense cooling fan grid is not the
most efficient way of pushing air through.
My project is for a pair 1200 w freescale dual fets for HF, hopefully with
some headroom for reliability.
