While this seems to be targeted for small low power web servers, I really want low powered, cool and low temperature laptops. Laptops with hot intel processors are cooking my body if I actually keep my laptop on my lap.
Modern processors draw very little power at idle; it's only at full load that they reach TDP. If your laptop is constantly doing something with its CPU then it will obviously get much warmer than one that's just idling. I have one with a Core Duo and it barely gets warm if I'm just reading static webpages and editing text, but really heats up if I'm gaming or watching videos.
I have the late 2013 MacBook Air with the new Haswell Core i5 CPU and it's the first time I can put my notebook on my lap for as long as I want without getting a heat stroke.
As long as I don't do computing intensive stuff like playing games or visiting some websites that overuse javascript the MBA runs really cool. Cooler than my body temperature.
