Antec Kuhler H2O 1220 Liquid CPU Cooler Review

Antec sit alongside Corsair as one of the big-boys in the All-In-One liquid CPU cooling market. They have been around for a long time and were one of the first to mainstream the trend of AIO CPU coolers. Their Kuhler series is renowed for its reliability, simplicity and good bang-for-buck. Today we have with us the latest exciting addition to the Kuhler H20 series, the Kuhler H20 1220. Why is this exciting you may be wondering? Well this is the first review in the world of the Antec Kuhler H20 1220 and to us a world exclusive is pretty exciting.

In terms of the design of this product, the innovation is probably not as exciting as you’d hope. The Antec Kuhler H20 1220 is essentially a 240mm Asetek AIO unit featuring a 27mm wide radiator, a standard Asetek pump unit and the flexible rubber tubing we see on the latest Asetek OEM designs. All Antec have done is branded the product with its Kuhler series branding, added a pair of their fans and offered up some basic fan control software. However, the fact this product carries the Antec branding and is part of the Kuhler series means you can expect quality, reliability and good performance.

The Kuhler H20 1220 comes in a very simply designed box and we can’t really see anything out of the ordinary – the key feature is the inclusion of the 240mm radiator.

    The current price of this cooler does seem unjustified but by the same token if you can pick it up a bit cheaper (I see all models of Antecs’ Kuhler on special often) tack on a couple of Noctua or Corsair SP fans, there’s reason to not use an Asetek (or Coolit for that matter) AIO cooler. Failures aren’t as common as a lot of people think.

    It has little to do with the instant failures.

    That H50 pump on that thing is a POS and it most notorious for AGING.

    Use it on a 2700K at 5.2 for 2 years, open it up, look at what it looks like, then come back and talk out of your ass.

      They’re not unless you like changing your cooler once in every few years.

      A big air cooler is the way to go over these.
      This is coming from someone that used both a H80 and a H100.

    What bothers me is that my i5 2500k@4.3GHz runs at ~65 degrees celsium during full load running small fft’s with Prime95. I’m also using this Kühler 1220, but with Arctic Silver 5 as a thermal compound instead. I’m also just using the included 120mm fans in a push-config with the standard fan-profile in Chillcontrol. Could the thermal compound the reviewers used really lower the temps that much? I mean what the hell? My idle temperatures are the same as what they’re getting under load.

    • Don’t forget we are using delta temperatures – that means you have to add room temperature to each of the results (+21-23). We also delidded our CPU so the thermal conductivity is improved (so that saves about 7~ degrees), and we use GC Extreme which is often 3~ degrees better than a lot of competitors (including AS5). So add room temperature to get the actual temp, then maybe another 10 to account for the delid + better thermal compound. Our results are more to show for how this compares to other coolers rather than the exact results you should expect at home.
