    There are issues with the temperature overheating, according to Pololu the vnh5019 is limited to overheat at 20 A for the duration of 20s (instead of the VNH2SP30 with 35s), at 15A just 90s instead of the 150s in comparison with the VNH2SP30. Cooling is more important here, due to the space constrains really difficult to put a big cooler on it.

    yes, I agree, it's good to put a heatsink on the hot side of the peltier module

    better or not ? it depends on your criteria
    - heat sink and fan is simplier
    - peltier + heatsink + fans will cool much more and would be a nice experiment to lead :)

    but this was just a theorical idea for fun :cool:
