Many years ago a CoolIT Systems released one of the first 120mm AIO liquid CPU coolers to hit the market and although they were not really the only ones to do so (Asetek did too) i still recall the somewhat "special" design their model had largely thanks to the external temperature screen (something which we haven't seen ever since). Since then the AIO market has expanded quite a bit so CoolIT, Asetek and a few others have released numerous models over the years for the majority of the leading companies in the world (for example CoolIT only offers products through Corsair now) and for virtually all segments of the market from entry-level 120/140mm ones and up to high-end 240/360mm ones. Today on our test bench we have the latest 360mm AIO Liquid CPU Cooler by our good friends over at Thermaltake, the Water 3.0 Ultimate.
