Some good examples here already. The one I was optimistic about (it was never super hyped but sounded interesting) was laptops that would have heatpipes bringing the heat from the CPU to the lid were it would just dissipate - so using laptop lid as a radiator. I remember they were saying it could dissipate ~20W continuously (which was not enough at the time ~2005?) but lots of laptops now could be completely fan-free.
I can't find much about this on google, but I swear it was a thing. Some people discussed it on this website for half-baked ideas:

- zeusk 3y agoMicrosoft has sort-of used heat dissipating lids but that's because the lid itself contains the CPU (surface book, surface pro).
- toast0 3y agoI think you run into a couple problems with this idea. It seems mechanically challenging to have a heatpipe that can flex as needed for a laptop. LCD performance is connected to temperature, so if you pull a lot of heat to the screen, you're going to see weird effects as the heat distributes unevenly. Moving the cpu to the lid is probably a better idea, and some devices have been made that way, but it's not common either.
