Technically, no, air is a much worse thermal conductor, and most liquids are significantly better. It's a pretty efficient thermal INSULATOR, however.
The practical applications, however, make the movement of air OUT of your system an efficient cooling method.
Not trying to be contrarian or a smart-ass, but aren't water cooled systems kinda just air cooled systems with the radiator moved elsewhere?
Every liquid cooling system is pretty much that. Eventually you need to give it to the outside and the outside is usually air. Heck even river cooling for Power plants ends up "air cooling" through the rivers surface.
All of that air cooling is just radiation cooling in the end
All of that radiation cooling is just entropy cooling in the end.
The heat is not going anywhere in the long run though.
