Liquid-cooling is nothing new in the world of computers; enthusiasts first started creating custom water cooling setups back in the 80486 era, and even prior to that some mainframes used liquid-cooling. Due to their cost and complexity however, such cooling solutions often do not appeal to a large portion of users. With the advent of of closed loop, ready-to-run liquid-cooling kits from Asetek and CoolIT a few years back, however, liquid-cooling is now significantly less costly and complex. Today, the cooling solutions of both these two OEMs are being marketed by several brands and are becoming increasingly popular among all classes of users. Today we have NZXT's Kraken G10 GPU cooler; read on to see how it performs relative to the stock air-cooling solutions.
