If I can find a suitable sized Peltier device I will try this and post findings. I heard about this concept when I was in highschool and didn't pay it much attention because overclocking was limited more by hardware than cooling in those days. Now I decided to do a little more research, both google and wikipedia have been invented since then, and there is alot of material out there. This can give you a brief overview of the concept: Thermoelectric cooling - Wikipedia, the free encyclopedia
And this will ring home with more of the visual oriented group (this link listed on wiki's page)
