There's a couple things that determine the heat output of a cpu, the main factor is simply the TDP design of the chip. Since every cpu is basically just a glorified heating element that runs code, you can determine the approximate amount of heat the chip will make by looking at the amount of power it's designed to use.
Wikipedia says the turion line has a TDP between 25-35W depending on model. Most desktop chips are running anywhere from 60-120W. Now my thinkpad has an i7-3720QM which I would certainly classify as a "high performance high GHz CPU" and its TDP is only 45W. Combined with the adequately sized heat sink, and the new power management features Intel puts in their chips, my laptop barely gets warm doing daily tasks, running tasks with the dedicated gpu is a different story of course.
Keep in mind the TDP is the max consumption of the chip, various power management features and the load on the chip will change output. My i7 can go up to 3.5ghz, but the power management will reduce that to about 1ghz of the load is low, and that makes a big difference in heat and power consumption.

Does anyone here know how to accurately identify current and recent cool-running Intel and AMD CPU's by their model/chip designations? I hope the family of cool-running CPU's that started with Intel Centrino and AMD Turion still exists.
All 3 of my well-dated laptops (2006-2009) have AMD Turion x64 dual-core CPU's, and those laptops are still running quite cool and quietly with the fan only occasionally kicking in. In the meantime, my friends and colleagues with laptops featuring high performance high GHz CPU's have heat-fried quite a few of them, typically with a 2-3 year lifespan.
So, if and when I shop laptops again, I'd like to continue with cool-running CPU's. (Yes, I know there's a GPU heat issue as well.)
