Re:What about immersion (but not Freon) (Score 1)

Check out this submerged rig . The first attempt is using Florinert and Liquid Nitrogen, and there is a second attempt using Florinert and dry ice. They get some CRAZY temperatures, and apparently are currently working towards a third attempt. From what I've read, Florinert is used by 3M for testing electronics, and will dry off of components and leave no residue, so no damage will be done to your components. The stuff is pretty damn expensive though...
