Well, dyson stole this idea from Toshiba, so i'll steal it from him.
Did anyone ever tried to build a rectangular radiator fan using Bernoulli's principle (ref. also Venturi, Coanda)? Think single rectangular bladeless fan grabbing air from outside the case at increased rate over what normal fans can do ?

Say you have 4x140 rad, you build a hollow airfoil shroud around it (not sure for pull or push, need to install more physics into my brain for that), use couple of enclosed fans to run airfoil, which in turn will grab air from under the rad ? (or push it into the rad ?).

That way you can dampen fan sound, save on fans, save on energy.

What about static pressure in this case ? I couldnt find any hard data on dysons overpriced blowers...

Cool or what ? Or i'm just going senile ?

Have you heard hot loud a Dyson is though ! They use a high Rpm motor to generate the venturi, so I think it would be too loud for a computer IMHO.
 
I have done some fluid dynamics but even i am struggling with your proposition - care to draw us a sketch? :)
