Using a Thermoelectric Cooler
Aside from being a potential trip hazard, Peltier devices are very inefficient. They pump some heat from one side to the other, and introduce a relatively large heat source (from the inefficiency). 

So if you don't have an effective (big, or forced convection from a fan, or liquid cooled) heat sink on the hotter side, you may end up making both sides hotter, just one a bit hotter than the other.
