That is you can take the heat and radiate it into space as Infrared radiation. IR radiation is able to travel through space as it is made of photons.

I’m not sure how effective this would be for the amount of heat generated by servers, but it’s not actually fully disqualified as I thought it would be.

This is how the International Space Station deals with waste heat: www.nasa.gov/…/473486main_iss_atcs_overview.pdf

It’s very slow compared with convective cooling, definitely not practical for running any high-powered computer hardware, slow enough that it can be considered disqualified.
