depends on how lucky you got with your chip. and how bold you are with voltages. but honeestly though if your going with a peltier and water you mine as well just go get a vaporchill because it won't cost all that much different once you factor in the powersupply (cost over 100 dollars to power the 210watt ones which you need), electronics you'll fry when something goes wrong (lots of condensation issues with peltiers)
