You know 'space' is a vacuum, right?

I don't see how that would lessen their concerns? Exactly because space is a vacuum, cooling is harder since you can't do convection.

The math still checks out though. Scott Manley did a video on it, and the top comment has some corrections: https://youtu.be/FlQYU3m1e80

30% of terrestrial datacenter power use is cooling. Space cooling is easier!

What makes cooling easier in space? Isn’t it harder due to the lack of atmosphere?

Just need radiators, no fans, no piping, no ac compressors, no moving parts.

But, but—convection!

How? There is no heat dissipation without an atmosphere. I mean, you have dissipation via radiation but that’s very slow

Not that slow if the temperature is high enough. Power radiated is proportional to T^4

I don't want to run my cpus at optimal radiator temperatures... 1000s of degrees is not ideal.

Not on earth at least!
