There are so many coolers out there, but they are all different types. They range from tower coolers to low profile to water cooling. Over the past few years we have seen a lot of different coolers and designs, but the ones that have been used most frequently are the AIO (all-in-one) water coolers, where everything is included into a closed loop while giving you the benefits of water cooling along with being affordable and easy to setup. Today we will be taking a look at the Antec Kuhler H2O 62O, which is a closed loop water cooling system which is produced by Asetek which is also the maker of the Corsair AIO water cooling systems. Let’s take a look…
Special thanks to Antec for providing us with the Kuhler H2O 620 Liquid CPU Cooler to review.

Packaging
Well the Antec Kuhler 620 comes in a box about the size of a older power supply box. It is shrink wrapped also to protect it from the elements since again it is a AIO water cooling system. On the front of the box they have a detailed picture of the unit all together.
Now on the back of the box it goes into more detail about the water block /pump and the tubing and the copper base plate for the cooler. Here is also a shot of the contents of the box will still all packed together.

I think there’s a mistake there. 8 out of 10 score? the picture there is 9/10 😀
Just a heads up all – if you get a KUHLER H2O 620 and want to set up two fans for push-pull, you need to ask for 6-32 x 1-¼ inch screws. You should be able to find these at hardware or hobby stores.

Just got one, results for stock speed Phenom II X4 965 are impressive. 3.4 X4 965 BB on ASUS M4A785-M MB. Room temp 22c, Idle 27c, Prime 95 4 hours 39c. I will test overclocking shortly.
The kuhler h20 620 replaced a Zalman (sorry don’t know the model #) all copper, w/120mm fan.
With the Zalman, PC would Idle at 34c and 57c at max load on stock 3.4 Ghz.. The Kuhler is very quiet and the Zalman sounded like a vacuum cleaner when the fan was adjust past 1800 RPMs.
I need to test it some more, but so far ,so ggod.
You could at least mention WHAT HARDWARE you had to buy to set up the push pull config.
I don’t care for a review, that adds hardware not included with the item.
Therefore the review skewed and making it non-withstanding,
I expected better, I want a review to tell me “out of the box” why not go with a differrent thermal paste, other fan configurations etc etc. bogus review
