Corsair had great success with Asetek’s low cost liquid coolers back in 2009 and while they have moved onto new pastures, Antec’s Kühler H20 620 has slipped into the market with a unique take on the liquid cooling concept. The reason for buying one of these coolers is simple. You want an easy set up liquid cooler to reduce noise levels and increase cooling performance, particularly for your overclocked system. While KitGuru has always stood behind the amazing Noctua NH D14 cooler, there are some downsides with this cooler, mainly the huge amount of real estate it demands inside a chassis. Antec are well known for their computer cases and have been an enthusiast favourite for many years now. The Kühler H20 620 is their first liquid cooler however so a lot rides on the performance. It is worth the cost?
