Antec introduced V4 series design updates for its Kuhler H2O 620 and H2O 920 closed-loop CPU coolers. The new coolers are outfitted with a higher-pressure pump, and split-flow copper fin design in the radiators. The company claims the two innovations work to drop temperatures down a further 2-4°C, over temperatures previous versions achieve. Lastly, the coolers are labeled with guaranteed support for current and upcoming CPU socket types, including LGA2011, LGA115x, LGA775, FM2/FM1, and AM3+/AM3/AM2+. Prices remain unchanged.
