I might be wrong, not claiming as an expert in this issue, but AFAIK, the card problem lies on the weak & insufficient VRM design and/or number, making it dual PCB will certainly provide more estate area for bigger and more extensive VRM design. Better designed, stronger VRM will yield lower power consumption, lowering the temperature overall, thus helping the TDP characteristic of the card itself.

And i'm certainly not only suggesting in using dual PCB, but also extending the length of the card ala HD 6990, that will certainly add some volume to ease your concern. Bottomline, nVidia has the bigger, more power hungry chip in this generation, how on earth they try to fight the physic by forcing a smaller PCB, weak a$$ VRM, and silence at all cost philosophy upon this card ???
