Making your radiator hotter than the thing you're pulling heat out of is very, very expensive in energy terms. This is why home AC is so expensive and why nobody uses systems like this to cool computers. All that energy has to come from a solar panel you fly, too, so you're not saving mass by doing this. You're just shifting it from cooling to power. If you need 200W to cool 100W of compute, you're tripling the amount of power you need to do that work.

Also, peltiers are less energy-efficient than compressors. That is why no home AC uses a peltier.
