I think the rate of cooling depends on temperature much more than the rate of warming up, because T_sun—T_planet >> T_planet—T_space. So a faster rotating planet should be warmer.
And this explains a lot. The so called Faint Sun Paradox is then not a problem at all.
Early Earth was much warmer despite of a fainter Sun mostly thanks to its faster rotation. Partly also because of a smaller distance to the Sun back then, but mostly because of its faster rotation.

Cool (heh). Good thinking!
Of course.

It’s quite elementary if you think about it.
