Nope. These were fan/heatsink combos. No peltier coolers to be seen. The boxes for the particular ones were simple "generic" Taiwanese cardboard boxes with no mention of Peltier cooling. Although he did have some of those, IIRC.
It is physically impossible for a heatsink/fan combo to cool anything lower that the ambient temperature around it because it's based on radiating the heat to the surrounding air. The fan is only there to move the heated air away from the heatsink and doesn't do any active cooling. So this must have been a scam since you say that they weren't peltiers or any other such cooling.
