> A bigger issue is the lack surface area for cooling. Not even The Expanse gets that one right. This depends on the working temperature of the radiator too.

In theory if area needed to be optimized a (series of) heat pumps could shed more power from a hotter radiator. If future designers want to be cute about it they could stick a high temperature radiator at the front of the ship as a headlight and lower temperature radiators in the back for a tail light.
