This is a followup to my post from yesterday where I provided time-dependent model results of the day-night cycle in lunar temperatures. One of the fascinating things about the model result (which I would not have expected) is that all other things being equal, the faster a solar-illuminated planet rotates, the warmer its average temperature will be.
