Something else to note FYI - thermal paste is essential even for some peltiers. Take for instance the wonderful Arctic Silver http://www.arcticsilver.com/ - it helps to fill the air gap between surfaces, so it actually HELPS to transfer heat.

The problem right now is lack of surface area. My poor little switch is a prime example of this - the heatsink it shipped with had so much glue underneath it and so few fins that it was a nice toasty 70C! Heatpipes are no good also, because you need a large heat difference between the heat source and the outside, so you'll usually end up with about 50C on the cpu and 60C outside. Also, while peltiers are great, as mentioned many times before, they only MOVE heat, so guess what that means? That's right - you better have a heatsink the size of a radiator to dump all that heat out.
