While unfamiliarity with the Thermaltake name requires residence under a rock in a remote land, this big named company has also been producing water cooling kits and components for several years now and as such is a known name in the business. Today, I have the Thermaltake ProWater 850i, a complete liquid cooling kit for your CPU. While complete kits don't have the best reputation for performance, they do serve as fantastic introductions to the water scene. Their upgradeability makes them a great introductory choice for beginners and they come with thorough manuals to help ease the leap of faith that is liquid cooling.
