The water makes the system fail, so taking apart a freazer and using http://www.texastooltraders.com/Nifty-FST51-5-x-1000/General-Hardware/String-Rope-Twine-Tape/Duck-Teflon-Tape-p6294228.html to wrap around holds it at -35C, then the isopropal + dry ice gradients it by 140C coming out to 98Kelvin, which should be good enough to start working, but ice actually slows it down even through the parafilm, so you still need to spray it with http://www.amazon.com/Dupont-Snow-Teflon-Spray-DSR610101/dp/B0031T82NO. This could be used on any computer as well. I've stuck them on raw freazer elements and they just turn to ice in the african plains. Although, freazer elements can be really cheap. Unlike an ice maker, its really noisy, but it never breaks down. Their all the same power mine cost about this much and takes up about as much as five 15in laptops http://www.sears.com/shc/s/p_10153_12605_SPM502567201P
