It doesn't get any hotter than the plastic end tanks but since aluminum transfers heat faster than plastic it also transfers heat faster to your hands when you touch it giving you the impression that it at a higher temperature. It is not.

Do not confuse temperature with heat and/or the transfer of heat. They are different.
