How to mount Peltier elements?

A peltier is a element that gets very hot on one side, and very cold on the other side. Cold enough (with enough power) to make frost all over it. So. I got one, I want to make nice cold cold air. I read wiki, if you don't heat sink it, it will self destroy. If I heatsink the cold side, then a fan on the heat sink to blow the cold freeze air, will it be fine? Or must I cool the hot side too? Peltiers are cool :D
