    so.. i bought this peltier and 2 heatsink + fan, and then i connect them to the adaptor 12 V, the fan works fine, but the peltier doesn't get cool, it just around 25C, and the heat also not very hot either, is there any ways to make my peltier cooler? *sorry for my bad english

    you COULD get one from an old computer

    checck your area for a ESS (electronic supply store) they have almost defintly have all these parts

    i would be inclined to check some online stores just type in heat sink on google

    Cool little project you have there. I just have a question.
