    Making a beefy Peltier cooler!

    I made one peltier cooler box similar to yours yesterday with a Polystyrene box. The cooler box consists of 2 pieces of peltier module that consume 120W in total.But I think the key of getting lower temperature is insulation. Since you opened a big hole on cooler lid, I doubt that hot air would back from that hole.
