Just a few days ago we gave you an introduction to air cooling. Today we publish the sequel, which is an introduction to water cooling. Water cooling has become a trend which rapidly spreads among experienced users, and the confusion disappears when pre-made systems start to show up on the market. This article mostly looks at the different parts of a water cooling system and how they work, but also a few things you should have in mind and on top of that a little theory. Nice reading for the interested users.
