Just posting this up to judge possible interest. A little background. I am a long time lerker and infrequent poster. Over the last 4 years I have built 3 watercooling systmes and a phase change system so watercooling is not new to me. I am a student at Georgia Tech and in one of my classes a professor I have mentioned a special coolant that he had developed for the automotive world which incorperated a specially doped nano-particle. It worked great but the only problem was the cost of a complete cooling system's worth was not cheap and in the OEM world where they measure the cost of a part out to the 7th decesimal place, water is alot cheaper. I talked to him about using it in a computer watercooling system and now I have some sitting next to me waiting to be tested. His guestimation is that it should reduce temps by at least 5C. With the jet impengement blocks it should be more because of the particles contact with the waterblock. I am currently waiting on some parts to come back to get my main computer back up but once that occurs I will post results. While he was developing the fluid he found that the heat transfer coefficient was increased 300% over water in turbulant flow and 30% in laminar flow. So this should be very benificial to any jet impengement block. Regardless of how good it works, how much are people willing to pay for a significant temp drop (2-10c)?
