Last I remember from OCN's newsfeed, they had working graphene transistors in lab that had thermo dynamic cooling properties under operation: The CPU cools itself. Now stack layers of transistors one on top of each other and you have: a super cooler?
Exactly. Here is a news post from 2008: http://www.overclock.net/t/321381/newsscientist-1nm-carbon-transistor-invented/0_60
Also, I also remember reading something about how a certain kind of graphene transistor was able to utilize the waste heat, therefore cooling the processor.
With graphene transistors the number of transistors that they could pack onto a die will be ridiculous. Silicon may be coming to an end when it comes to making chips, but that doesn't mean that there aren't other materials out there that would keep this "law" from failing.
As for heat issues with these newer chips, the answer is reducing the voltage needed to power these chips. The 3D transistors that Intel are making right now are quite new on the market, and with improved production process I foresee a large drop in the voltage needed to power these chips. This will go a long way in fixing the heat issues.Edited by AtomicFrost - 5/1/12 at 10:16pm
