It's not been my experience that things are getting worse in that respect; in fact, I'd say heat-wise things are significantly better than previous generations.

Intel has put a lot of effort into making its chips more energy efficient, which has a side effect of generating much less heat. I'd guess that, combined with better chassis design, accounts for the improvement.
