Arthur T Knackerbracket has found the following story:
Getting rid of heat is one of the central challenges with modern technology. It doesn’t matter whether the technology is a high-end server CPU or some pathetically anemic processor in a no-brand set-top box, someone has had to think about thermal management. One of the central issues in thermal management is thermal resistance, a material's tendency to limit the flow of heat. The thicker a material, the larger the temperature gradient required to achieve the same amount of cooling because the thermal resistance increases with thickness.
Except when it doesn’t; if the heat is carried by ballistic phonons, then thermal resistance stays constant.

>> Heat diffuses like the stain growing up the wall of a teenager’s bedroom.
...what?

Chris Lee is the physics explainer man at Ars Technica, but he seems to be channeling the spirit of Peter Bright.

I don't get it. You mean that stain on the wall is actually Peter Bright's?

ArsTechnica got really weird a long, long time ago.
