Antec, the company mostly known for its quiet components aimed rather at multimedia than performance enthusiasts, has unveiled its first ever liquid cooling solution (LCS) for central processing units (CPUs). The Antec Kühler H2O 620 is completely sealed and easy to install, thus, may be used even by those, who have not previously utilized liquid cooling systems because of complexities of installation and high price. The novelty is both affordable and easy to install.


Antec Kühler H2O 620 is a completely self-contained system that consists of a CPU water block with copper base, large 151x120mm heat-exchanger as well as 120mm cooling fan with 1450 - 2000rpm speed. The product - which was developed in tandem with well-known LCS specialist Asetek - can be easily installed into almost any modern computer just like any other cooler and the only condition is presence of a place to install a 120mm fan. The Kühler H2O 620 is claimed to be 20% more efficient compared to stock coolers, which is a rather big deal.

There are more advantages that sealed liquid cooling systems have over traditional air coolers. Firstly, such coolers route all the CPU heat directly out of chassis, which means lower overall ambient temperature. Secondly, the low physical size of water-block drastically reduces the footprint of CPU cooling system, which greatly increases overall airflow inside chassis.

“With CPU cooling, today’s users care primarily about four things: performance, low noise, reliability and ease-of-setup – all offered at the right price. The new Kühler H2O 620 switches it up and packs a remarkable amount of cooling in a compact solution, and one that delivers performance greater than many of the tall dual-fan CPU coolers that barely fit into a system,” said Scott Richards, senior vice president at Antec.

The new Kühler H2O 620 is compatible with present and future central processing units, including AMD microprocessors in AM2, AM3, AM2+ and AM3+ form-factors as well as Intel's chips in LGA 775, 1155, 1156 and 1366 form-factors.

One of the remarkable things about the Antec Kühler H2O 620 is its price: $69.95, which is comparable to high-quality air coolers. The pump in the Antec Kühler H2O 620 has an MTBF of 50 000 hours, which is over five years of 24-hour-a-day operation. The novelty is backed by Antec’s Quality 3-year (AQ3) limited warranty on parts and labor.
