[QUOTE="pigoo3, post: 1293200, member: 56379"] I like to compare things to other things. In automobiles...water & petroleum products are used to cool various systems: - Water + antifreeze to cool the engine - oil to a degree to lubricate & cool parts - transmission fluid for the transmission (cooling & lubrication) - differential fluid for the differentials All of these systems can have a "radiator" incorporated into them for cooling. I think generally speaking...the petroleum products are used for lubrication (since they make physical/direct contact with the parts) and resistance to thermal breakdown. But because they're thicker (more viscous than water) they may hold more heat, are harder to circulate, and need more surface area to cool them. How does this relate to a water-cooling system in a computer? A liquid such as water is probably easier to deal with...pumps easier, easier to cool (but it may boil if the system doesn't cool enough or if some sort of glycol/"antifreeze" isn't added to the water to raise it's boiling point). One difficulty to setting up a water cooling system in a computer that never had one is cooling capacity (btu's generated vs. btu's of cooling capacity). If you don't have enough cooling capacity...the laptop may eventually get hot (depending on hours of continuous use). If you have too much cooling capacity...then the system may take up too much space. So it may be a "trail & error" experiment for a home user/experimenter.:) [/QUOTE]
