you can't run the thing bare and expect one side to get icy cold.
The Peltier effect basically operates on a P-N silicon diode junction, and all it does is create a temperature differential. Two consequences:
(1) The Peltier element dissipates a LOT of energy, hence creates quite a bit of its own heat.
(2) The Peltier element merely creates a temperature differential, so if you aren't getting the heat removed from the 'high' side you will end up with one hot side and one REALLY hot side.
Beyond that I'm no help, I've seen one but haven't fooled with them first hand  However you could try sandwiching your Peltier element between two CPU fan/heatsink combos, and then be able to observe the effect much more clearly...
