Antec Announces Newest Next-Generation CPU Cooler: KÜHLER H2O 620

Antec’s KÜHLER H2O 620 uses Asetek technology, sets latest standard
in high-performance and quiet CPU cooling

Fremont, CAJanuary 20, 2011 – In its 25th anniversary year, Antec, Inc., the global leader in high-performance computer components and accessories for the gaming, PC upgrade and Do-It-Yourself markets, today announced the Antec KÜHLER H2O 620 next-generation high-performance CPU cooler.

Working in tandem with Asetek (,) the industry-leading supplier of OEM liquid cooling systems for computers, Antec has developed an easy-to-install liquid CPU cooling solution that outperforms stock CPU coolers up to 20 percent under full load. The Antec KÜHLER H2O 620 is crafted to bring sealed liquid CPU cooling to mainstream PC hardware and gaming enthusiasts world-wide – all delivering a Quiet Computing™ experience that requires zero maintenance, and that’s built to OEM standards for reliability.  

The KÜHLER H2O 620 features Asetek’s low-profile pump for exceptional liquid circulation while preserving internal airflow, and easy-bend tubes for maximum flexibility in radiator positioning. Additionally, the KÜHLER H2O 620 utilizes liquid temperature controlled fans to deliver Antec’s renowned Quiet Computing™ technology for quiet, efficient performance and uses the latest generation copper cold plate for optimal conduction.

“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,” said Scott Richards, senior vice president at Antec. “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.”

“Combining high performance and quiet computing has never been easier than with the KÜHLER H2O 620 cooler’s liquid temperature fan control,” said Steve Branton, director of marketing at Asetek. “Simply plug the fan into the pump and the cooler provides great performance when you need it and stays whisper quiet when you don’t.” 

The KÜHLER H2O 620 high-performance CPU cooler is backed by Antec’s Quality 3-year (AQ3) limited warranty on parts and labor and is available at the end of January for an estimated price of $69.95 through major retailers, e-tailers and distributors.
