Well,

I got one of those TEC 12v car cooler things. Took it all apart and it had a 40w pelt inside. All the other ones I have seen have the exact same specs so I am guessing they all pretty much come with 40 watters. My plan is to replace that 40 with a 172 watt pelt and fill the aluminum tub its attacted to with water and use it as a water chiller for my CPU. I am almost 100 percent sure that it will work its just a matter of how well. With water inside the water would get down to about 42F and thats with the stock 40 watt pelt (the thermometer I had only did F). Just by redoing all the thermal connections with AC5 cut the water temp down to 38F. I would do a bigger pelt but it is only 40mm x 40mm and the highest wattage pelt that size I could find was 172 watts.

I tried talking about this at the Hardforums but the children over there had nothing but negative to say. My roomate also has very negative things to say like its a waste of time/money and I am like what is it to you? Its my time and money. I think he is afraid it will work.

The only other problem I forsee is that the tub is aluminum and the waterblock is going to be copper. Probably a Maze 4. I am afraid of galvanic corrosion. Because of the interaction with the copper and aluminum. I have talked to some professional engineers who work everyday with metal finishing that say aslong as they don't touch and I use plastic tubing with distilled water to cut down on the available ions in the water I should be fine. Putting alittle antifreeze in will help too. One of my other options would be to get some silver nitrate and run it through the copper waterblock which would give me a silver coated inside of a waterblock and copper nitrate. But I was told thats alittle extreme and I shouldn't have to do that.

Thoughts and opinions? Suggestions for improvements?

Oh! Just thought of another question. Inside this thing it has a aluminum coldplate. Where can I get a copper one made exactly the same way?
