The elevated temperatures of the overheating components are such that fluid flow, not temperature difference, is the thing to go after, and it also has the advantage of being much simpler than adding a whole refrigeration cycle. These problems start to read like problems from nuclear power, where sufficiently uniform flow is a huge deal so that various materials aren't compromised in the reactor.
