What do you guys think about this?

I want to cool the water in my systhem with this (http://www.zing.com/picture/p28e6bf0c045203141dfef4955b79a05d/fe8f6d28.gif.orig.gif). You think it will work well? Can I cool the peltier with just a fase fan?

Absolutely not. You will need a VERY good heat sink on the other side with a fan. Also, most poeple seem to think that you get better results with a misting effect over the cold-sink, or a waterfall, that way the peltier stays charged. Either way it should cool your water at least some. Good luck with your experiment. By the way, I doubt you should try it with a peltier bigger than 80 watts.
