How effective would it be to remove the fan (just the fan, not the whole heatsink) from a GPU and duct a 120mm fan into the cooler so all the air it moves goes through the GPU heatsink? You could get a ton of air moving with no noise.

How much air does a high end GPU cooler actually move?
 
IMO, it's not really so much the fan as much as the heat dissipation design. If the heat sink puts heat pipes and stuff to good use, it could potentially be fanless (see the HR-03), but when you do add a fan, it cools even better.
 
Really depends on what heat sink it is. I zip-tied a 120mm fan to my Zalman VF-900 and it works just fine, but I'm almost positive that you won't have very good results with the stock cooler on most cards.
 
I mean something like this. Remove the fan, and blue shaded part of the cooler, and duct all of the air from the fan into the cooler (black lines) so it flows through the heatsink and out the GPU exhaust. It would function exactly the same as the blower fan on the GPU but could move a ton of air quietly.

i dont know if they air would pass through the heatsink correctly, it would really have to be done right, but i think to cool the GPU better i would find something with a bigger heat sink, like the artic cooling ones
