Antec Kuhler H2O 620 Water Cooler Review

In the world of home computing, using water cooling started off when a couple of enthusiasts tried to achieve high overclocking performance on their (at the time) top of the line 486DX processors. Within a few months the trend took off and many enthusiasts and overclockers were designing and building their own parts, when companies offering ready parts and even ready to assemble kits began to emerge. It was not until years later that companies released closed, ready to run water cooling solutions and still only a few are available in the market today. Antec has just released such a water cooler, the very compact Kühler H2O 620, which also comes with a very interesting retail price tag. Will it manage to outperform the humongous air coolers available today? We will find out in this review.
