My GTX 260 55nm idles at around 50C. Even with a new node, 3 billion transistors are going to produce heat. There are plenty of factors that play into how that heat is dissipated, resulting in the perceived temperature at any one point; even if true, it's not the end of the world. Assuming these figures will be true of released units, then the only real impact this will have is on overclockability (and perhaps lifespan, if the proper precautions haven't been taken).
