Cooling your CPU is one of the most important parts of any computer system. Without it you would very quickly make your computer redundant as the CPU would be a bit too toasty for its own liking! Most of the time we rely on air cooling as it is the most readily available heat transfer medium available to us in a case.

Some extreme gamers several years back started looking at ways of cooling a CPU using different transfer mediums such as water or even the extremes of liquid helium and liquid nitrogen (do not try this at home!). It was found, not surprisingly, that they had more cooling potential and were generally more efficient as they could remove more heat from the CPU for the same amount of energy or work done on the physical system. That said, there are a few obvious problems of having water or any other liquid in close contact to electrical components.
