The area of radiator needed directly corresponds to the amount of power harvested by the solar panels. It doesn’t matter what the load is. So a compute frame with the same amount of solar panels as the space station would need approximately the same radiatot area as the ISS, unless you are bringing nuclear power into the mix.

I agree that space based datacenters are a bad idea, but the thermals really are not the gotcha people are making them out to be.

Radiators in space work by radiating electromagnetic energy(light). Heat can only accumulate in matter, not in space, so that is definitely not one of the things we need to worry about.

With radiators just like with every existing satellite system.

Very large scale datacenters would likely have some nasty fluid handling problems to solve.

I’ll just note that I am not a fan of putting internet infrastructure in space. I think polluting the upper atmosphere with a bunch of metals every time a satellite deorbits will certainly have negative consequences. So IMO space should be limited to things we can’t do with earthbound infrastructure.
