So for the past two months i've been trying to get a gallon of water to chill to about 40-50 degrees in temp. in about 10-20 minutes. I wanted to use two TEC's(Thermal Electric coolers) attached to some heat sinks with fans expelling the heat. This would also be underneath the water/reservoir that i will buy, it will also be insulated to the best of my ability. I am wanting to know if this would work or if there is a better way of doing this. I also don't want this to be very big anything bigger than 12in*7in*6in(L*W*H) would be too big.
