As anyone knows, temperature should be more easily controlled at higher altitudes, not the opposite.

That doesn't seem to be correct, at higher altitude though the air is much colder, at the same time it's also much less dense. Without air to contact with, the radiator may find it more difficult to transfer heat. High altitude engines typically required larger coolers for that reason.
Generally, overheating seems to have been changed accross the sim, 109Es for example are now seem to overheat very easily and are much more difficult to keep in line. Their cooling system can't handle engine heat at historical settings.
