wait isnt the point of blower's to blow the dam air OUT!
With this setup each core should gets its own set of cold air. If you push all of the air out of the case, the fan would be on the inside end and air would pass by one core, get hot, then pass by the other core. This would SEVERELY diminish the effectiveness of the cooler and the ability to overclock it. Either that or you have to design some good ductwork to funnel the air from the inside end of the card back to the outside, this would cause the effective size of the cooler to diminish and would require a MUCH stronger fan to push the same amount of air. Also, the side that doesn't have the ductwork would get better cooling as there is less resistance.

tldr; The current fan placement and air ducting directions make for the best design.

DP GFLOPs (DP is used a lot for high precision molecular modelling calculations) for the 6990 is estimated at 1277 while for a pair of GTX 570s it is estimated to be 351. nVidia cheaped out on the consumer GPUs (Fermi) as compared to scientific GPUs (Tesla) with DP floating point units.
WANTS GPU3!
