Introduction

Finally, there is a liquid cooler for the rest of us. The Antec KUHLER H2O 620 delivers high-performance liquid cooling for your CPU in a quick, easy-to-install package. Unlike traditional liquid cooling systems, this self-contained unit comes prefilled and requires no maintenance. The voltage-controlled 120 mm fan, 3rd generation copper coldplate and airflow-enhancing low-profile pump ensure efficient cooling, while the estimated 50,000 hour pump lifetime means this cooler is even likely to outlast the system it cools. Easy-bend flexible tubing allows the KUHLER H2O 620 to be installed in nearly any orientation regardless of the internal configuration of the case. Finally, the KUHLER H2O 620 comes with peace of mind in the form of an industry-leading Antec Quality 3 year limited warranty on parts and labor. Take your PC’s Quiet Computing™ to the next level with liquid cooling performance at a price that rivals aftermarket air cooler.

I decided to purchase this unit to cool my over-clocked Sandy Bridge(4.4Ghz) i5 2500k processor. Previously I had installed a Cooler Master 212+, and was fairly impressed by that "air cooled" unit (all temperatures were well within the acceptable range, below 60C). So, this was not an upgrade based on necessity, rather I wanted to keep my CPU as cool as possible for longevity purposes. Also, I like the low-profile look of these water units better than the huge metal structures offered by many of the air coolers. After the installation I was very pleased with the units performance, and can say that it really is an incredible bang for the buck! Read on for more details..

Out of the Box:

One of the first things you'll notice when un-boxing the Antec Kuhler H20 620 is that the unit is very light-weight. This facet is something I prefer as I feel it puts less stress on the CPU and motherboard when compared to previous units I've used. The look of the unit is fairly standard and if you are familiar with the Corsair H50 and H70, you'll find that the head unit is identical to the one employed by the Corsair H70 and the radiator is that of the Corsair H50. The reason for this pseudo-phenomenon is that all three units are manufactured by the same company, Asetek. Perhaps the only noticeable difference is the more flexible tubing in use on the Antec cooler. Asetek, the manufacturer of the unit, says that the Antec model uses the latest(3rd-generation) copper cold plate (head unit) and less flow restrictive tubing. The other discerning element between the Corsair series and the Antec is that the fan/radiator setup on the Antec exhausts the warm air out of the case rather than inside(again my preference).

Installed on an Intel i7 2600K socket 1155 CPU. The installation guide does not mention socket 1155 even though the sales literature lists 1155 compatibility. Installation guide covers AMD AM2/AM3 and Intel sockets 1156, 1366, 775. (Manufacturer's web site had same guide as received with the product so it provided no information on socket 1155 installation.) Guessed that 1155 would be same as 1156 and this was a correct guess.

Installation is actually easy but the lack of detail in the supplied guide can cause installation delays. Step 1, prep of metal retention ring, provides horizontal clip orientation but not vertical orientation (refer to image on step 7 or 9 to get vertical orientation). Step 2 (backplate prep) image shows socket information on 1 of 4 corners for mounting the tension clips. If you use this orientation on each of the 4 corners, the backplate won't fit when you get to step 4. The clip position for each corner is different. The socket information for each corner is molded into the backplate in a small font and probably won't be seen until you realize the backplate doesn't fit. In bright light with 20/20 vision, you can read the molded numbers and execute step 2 properly. The remainder of the installation is sufficiently intuitive to execute properly with the minimal detail provided in the installation guide.

Once installed, the performance is great. System is OCed to 4.4 GHz. Stock Intel cooling provided less than 5 minutes at 100% CPU utilization before the CPU temp exceeded 85 C. This cooler keeps the temp below 70 C under all load conditions. Using a BOINC project to achieve continuous 100% CPU utilization, CPU temp was typically 62-64 C at nominal GPU utilization. Max temp was 67 C when both CPU and GPU were at 100% for an extended (>1 hr) period. Computer cooling problem solved!

I build a fair amount computers, and a give each one a healthy over-clock. Therefore, I look for coolers that are easy to install while performing well in order to keep the CPU temperatures as cool as possible for maximum longevity. I previously used a lot of the larger metal conduction heat sinks, and had great results with many of them in terms of CPU temperature. However, for aesthetic and noise purposes I have been swayed into using the Antec Kuhler 620 h2O (the smaller version of this unit). I have been so pleased with that unit, that I desperately wanted to get my hands on this "upgraded" version. It's not perfect, but it is excellent none-the-less, and will likely appeal to the majority of computer enthusiasts.

Out of the Box:

One of the first things you'll notice when un-boxing the Antec Kuhler H20 920 is that the unit is relatively light-weight despite it's size. The look of the unit is fairly standard and if you are familiar with the Antec 620, you'll find that this unit looks very similar with most of the differences only emerging when you compare the thickness of the head unit and the radiator. This is, once again, a unit manufactured by the company, Asetek (The group that previously constructed the Corsair H0 and H70). The tubing on the 920 is slightly thicker, but remains very flexible. Asetek, the manufacturer of the unit, says that this Antec model uses the latest(3rd-generation) copper cold plate (head unit) and less flow restrictive tubing.
