I've read quite alot about Fluid XP, most agree the claims are questionable at best, and considering the price probably not worth it. If interested head over to procooling for some good discussions on it.....

Water is great, unfortunately mixed metals in water loops is pretty common, so we typically need to have some sort of corrosion inhibitor. Another cocern with un-treated water would be biologicals.

Flourinert has been experimented with quite alot when it comes to computer cooling. Unfortunately last I heard it was still somewhere near $500 per gallon, considering this, its not practical for the average PC user.


There are a few Deicing, and anti-freeze formulas patented by the military. These are manufactured/marketed by a single company in Texas. They would probably be worth looking into, unfortunately its bulk purchase only.
