I think the picture in the header says it all, on one side I can see very dirty fans and on the other side the improved design. The first thing I would have tried is to replace the fans. I had to do this with other laptops I have had in the past (HP mostly) but never with the two models of MBP (and I run pretty hard too), so I guess it has to do with the model as he mentioned. While I sympathise with the idea of improving the design of a product massively consumed, I first try to think that the engineers did a well design and try to look for the malfunctioning component to replace.
