Hahahahahaha what?
I've had a laptop running at about 80-85C (175F ) and I haven't turned it off in 5 years. It's probably not great, but chips can handle way more than their optimal operating environment
Yes, its expensive for NASA to do it because they're bloated and rely on outside contractors for everything, but this is probably a big reason why Elon/SpaceX has been focusing so much on reducing launch costs per lb, and are now dramatically cheaper than everyone else by orders of magnitude
The math works if you increase the radiator's (heatsync) surface area enough, and control the rotation of the satellite to reduce direct sun exposure. Sure, the heatsyncs/radiators may be the size of a football field for a satellite the size of a mini van, but the fortunate thing about space is it has lots of space
Computer chips have to stay at 140F tops. The radiator would need to be the size of a football field for just one satellite. The international space station cost 150 billion dollars - AI satelites dont have that kind of budget my friend.
