the amount of cooling you get is proportional to the difference of component temperature to ambient temperature. thats why modern chips are engineered to run much hotter.
Actors tend to lead to bloated incomprehensible code. Even when you do want game objects to look like independent message passing actors. Faking it is always easier.
Actors are self defeating because they turn everything into a distributed system.
think of corrugated metal. sound waves and heat will travel slower in the wavy direction than in the straight direction. you can stamp some more complicated pattern onto a piece of metal to control how sound waves travel through it. almost like a sound circuit. (eg. passive sound canceling metal panels. things like that)
you could come up with some material that naturaly has those kinds of properties without being wavy. but mathematically its the same thing.
