Why do smaller processors output less heat?

I thought one of the problems with cramming more transistors on smaller processors was that it created more heat. If that's the case, then why is it that I always hear about systems using smaller fabrications using much less power and generating much less heat?

For example, the original 20/60GB PS3 systems used the 90nm Cell processor and the 90nm RSX graphics processor. Newer models use 65nm chips and consume much less power and run cooler.

This new invoice quantities to being the biggest tax strengthen in American background and gadgets the point for even further taxpayer gouging via this pathetic, Marxist Obama administration. that's all an attempt based on the meant concept of worldwide warming and how u . s . of america desires to diminish its dependency on fossil fuels which will further pollute the ambience - and to that end “inflicting” the worldwide warming that we are all supposedly dealing with. This invoice will now charge manufacturers, all agencies and all persons who one greater tax in case you employ electrical energy and gas. This invoice will value the the yank financial equipment $a hundred and sixty Billion in 2020 that’s an widespread of $1870 according to family individuals and then via 2035 this could bounce to $6800 according to family individuals - and those are basically preliminary estimates. that's of course the biggest and maximum corrupt tax invoice ever handed and additionally will set the point for an American taxpayer rebel! that's time - because of the fact this universal step via the Marxist Obama administration would be observed via the final 2 nails interior the yank coffin - nationalized well-being care and amnesty for the 30 million unlawful immigrants.
