[Star Wars] The Rebels and Empire couldn't operate their normal fighters on Hoth due to the cold, but how is Hoth colder than the vacuum of space?

Outside of being close to a star, space has an average temperature just slightly above absolute zero. So how could the Rebel and Empire fighters operate in space but Hoth is somehow too cold for them requiring the Rebels to use snowspeeders?

Space is technically cold, but vacuum is a really great insulator.   Most ships actually have to figure out ways to dump heat in space, rather than figure ways of retaining it.

That's probably what made the fighters hard to operate on Hoth in the first place.  They're designed to give up their heat easily, and thus Hoth's atmosphere quickly cooled the ships below operational thresholds.
