Just recently we show everyone what a high quality, high performance custom watercooling kit is capable off even when used with one of the hottest CPUs currently available. However although the pros of a custom watercooling kit are undeniable at the end of the day only enthusiasts, hardcore gamers and overclockers will opt for such a solution not only because of the somewhat high cost but also due to the time required to install it and the various things you need to watch out for such as leaks (mostly at first use) and the need to add more coolant when needed. This is also the reason as to why a while ago many manufacturers decided to launch their very own AIO (All In One) liquid CPU Coolers that have all four parts (radiator, tubes, pump, waterblock) attached from the factory to simplify things for the masses. Antec became well known for their AIO Liquid CPU Coolers with the KUHLER H2O 620, 920 and just recently the 1220 model which unfortunately was not very widely distributed. Well Antec is back and so today we will be taking a look at the smallest member of their latest KUHLER line the KUHLER H2O 650 Liquid CPU Cooler.
