"The second in my series of Antec reviews is the Kühler H²O 620, another self-contained liquid cooling unit for your CPU. The Kühler H²O 620 is a more basic, simple and cheaper version of the Kühler H²O 920. Although lacking some of the features of its bigger brother, we will see if the 620 wins in the value for money department."
