I've always wondered about this tho... I have enough knowledge of physics to get really confused, but not enough to understand how exactly it gets there.

There's still always heat, right? Using the energy for computation doesn't mean you're not still retaining the entire energy output of the sun inside a shell. You use the heat... But at the end you still have the heat.

Is it just that theoretically the outer shells are so big that it is simply diffusing the heat of the star across a vastly (vastly) larger area?
