> Windchill is a human experience and does not apply to physical objects like a computer.

It does if the computer is on and is exposed to wind. It has nothing to do with being human or alive, and everything to do with having an internal source of heat. Even in things that have no source of heat, wind chill will accelerate cooling until the object reaches the dry bulb temp (assuming there's no evaporation), as you mention... which rather obviously means it is not limited to "human experience".

You can argue that the term windchill refers to something typically used to describe human/animal outdoor comfort, but the concept is in no way limited to that.
