heres the quote of the day....
"According to physics, air is better for disippating heat. Water has a very low transfer rate compared to most materials. The big difference is that when you have cooling with water you have a liquid that has lower heat transfer than air but the bulk of it and the circulation changes all that. What makes water cooling better is that it flows over, and the water is then cooled. Your cpu technically is still air cooled, you're just creating a much much larger surface area for the air to cool it by using a conduit for heat transfer that is water cooling. Instead of cooling just where that little chip is you're cooling all around an entire radiator or tubing complex(whatever word you wanna call it). There are 10 times better conductors of heat one could use than water, air just being one of them but you can't really circulate and cool the air with readily available materials. Water is just available in large quantities so that's used as the conductor. Most of the better conductors also evaporate as well. The really serious people start getting into non-electrolytic fluids and dry ice, because honestly, water sucks. It's better than heat-sink/fan combo but in reality it's basically just giving the air more area to cool, the surface area works very well in cooling it then.
Air is more efficient than water when given the proper surface area. liquid cooling is required at the moment to give that bigger surface area so they are used together. If you could isolate the water in something like a thermos so the air can't really cool it you'd quickly see many problems after the water has passed through a couple times.
Another good point about water, it won't get too hot! it takes a lot of energy to heat up water since it's a fairly bad one! That's a big plus actually! just circulate it fast enough to keep it able to absorb more and more and you're fine"
now I know I have seen graph and statement after statement about water is 4 times better then water, and direct die is ten times better then water...
just I cannot remember where I heard this.
help me find the right proof here to get this right, without it just becoming a flame war arguement.
