LOL - no mystery.
The early (first) GK MB115 combos didn’t have the vent or fan - the vents and fans were added later (I’m guessing about a year or two later) and is what I refer to as the upgraded first generation MB115 combos.
EDIT: FWIW: I have both and I haven’t experienced any over heating with either.
