> Figuring out how to radiate a lot of waste heat into a vacuum is fighting physics.
Radiators should work pretty well, and large solar panels can do double duty as radiators.
Also, curiously, newer GPUs are developed to require significantly less cooling than previous generations. Perhaps not so coincidentally?
Well there lies the rub, solar panels already need their own thermal radiators when used in space ...
Great, so you seem to agree the technology exists for this and it is a matter of deploying more of it?
It's a matter of deploying it for cheaper or with fewer downsides than what can be done on earth. Launching things to space is expensive even with reusable rockets, and a single server blade would need a lot of accompanying tech to power it, cool it, and connect to other satellites and earth.
Right now only upsides an expensive satellite acting as a server node would be physical security and avoiding various local environmental laws and effects

You need to understand more of basic physics and thermodynamics. Fighting thermodynamics is a losing race by every measure of what we understand of the physical world.

1kW TDP chips need LESS cooling?
Yes, Rubin reportedly can deal with running significantly hotter.
That makes radiating a much more practical approach to cooling it.
I see what you’re saying - higher design temp radiates better despite more energy overall to dissipate.
