So for the ISS at 20c you'd get 481 W/m^2 so you'd only need 2.3m2. So comparing the ISS at 20c to space datacenters at 70c you get an improvement of 63%. Nice, but doesn't feel game-changing.

The power radiated is T^4, but 70c is only about 17.1% warmer than 20c because you need to compare in kelvin.
