Radiation is the part you are missing. The three ways of dissipating heat are: conduction, convection, and radiation which is what the "fins" do.
Doesn't it work out to something like a full kilometer of the things in order for it to work? The idea is pure madness.
Oh lord yes. Its why its stupid.
Depends on density. I think Scott Manley's analysis is probably correct. SpaceX knows how to deal with a few thousand watts of heat per satellite from starlink.
Then the question is whether a few kilowatts is enough compute per node to be worth the trouble.
