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.
The solar panels needed is another problem for the space data center fantasy. Once you put together all the mass over enough surface area to make it work, you would blot out the sun worldwide.
