Antec Kuhler H2O 620 Liquid Cooling System

Pros: excellent liquid cpu cooler must have for any pc build would recommend to any thinking of buying specially antec kuhler h60,keeps my temps extremely low at idle and full load

Cons: none

Pros: keeps cpu nice and cool. the installations was a little troublesome and confusing. gets the job done. I am noticing a considerable difference in heat when compared to a regular convection heatsink

Cons: odd installation but it works in the end.

Other Thoughts: would recommend and buy again

Pros: Looks great

Cons: I was going to get one.

Other Thoughts: I was going to buy the 920, but read reviews about there support and decided that if I got one that's defective I sure do NOT want to go thru there support. I would highly recommend to stay AWAY from companies with BAD SUPPORT. Go with a more known manufacture like Cooler Master or Corsair.

Pros: Cheap and easy installation, idle temp dropped roughly 9c after installation over the stock cooler from a FX-8320
(45c down to 36c). CPU temps around 50-52c at 100% load.

Cons: Radiator is gonna be a tight squeeze for some cases, for example the Thermaltake v3 had to modify the case and drill new holes about a quarter inch in the back to give myself room to mount the 120mm fan which fit before mod, to allow the radiator to be mounted. Not sure if its just mine or what but its actually quite considerably louder over the stock cooler (minus the turbo sound when the cpu starts warming up).

Other Thoughts: If you are looking for a cheap novelty way of cooling your computer this is definetly a good way to go. If your looking for something quieter and more efficient probably should look at other alternatives.(alot of the higher end air coolers will easily out cool this product)

Pros: Its cold, its quiet.
Way cheaper and easier to install than a full blown liquid cooling system. I recommend this to anyone.

Cons: The tubing was literally 1 inch too short to mount this system to the bottom intake fan of my Rosewill Thor V2 case, had to put it in the rear to make it work. come to find out Antec makes the exact same system with longer hoses so BEWARE if your getting a massive tower!

Pros: This little big bad boy always keeps my cpu at 50-60F during average use and when i'm loading it or playing a game on ultra settings it runs at around 90-125F max! I love this water cooler. Very simple design and from the looks of it newegg has stopped selling it or maybe a new shipment is taking some time? Either way if you got lucky and it isn't DOA then I'm sure it won't let you down.

Cons: I don't know why I'm typing this in the cons, but everyone on here is complaining on how terrible the instructions are... It seems as if you may have to understand the general concept at the very end. Who reads instructions anyways :P

Pros: Keeps cpu very cool, easy setup, quite

Cons: Fan will not work when plugged into fan header coming off of unit but will work when connected to one of the motherboard headers. Antec has to have the worst RMA process I have encountered. I have been emailing this people for over a wk now and I still have no RMA number. Keep asking for information that I sent once. How hard is it to just issue an RMA number. They treat people as if they have no assessment skills for trouble shooting. Out of 3 units purchased, only one works as it should as far as it powering the fan off the fan header on the unit. I replaced a Corsair H50 with one of these and its the worst decision I have made yet. The Corsair was 5yr's old and still works great and the Antec have had problems from the word go and I have to fight for an RMA #. Come on Antec get with the program for an easier RMA process.

Other Thoughts: Would not recommend this unit to a single soul and will not purchase another. Back to Corsair next time.

Manufacturer Response:

Hi,

I apologize for the non-response and the problem you're having with the unit. Seems like support you received is unacceptable. Please write us at VIP@antec.com and please refresh us of the case details and we'll look into this for you. Thank you.

Pros: I bought this back around September if i remember correctly, At first me pc wouldn't start, but thats another review for another time, but this thing, is awesome! It was very easy to install on my first build, keeps my cpu nice and cool, I love it.

Cons: I honestly cannot think of any, but i know others have had issues.

Pros: Had this unit on a 1100T for over a year, now on an FX-8350 almost 6 months. Works perfectly in my THOR case with no more than 56C after two hours gaming (CRYSIS 3 on ULTRA settings)

Cons: Won't go get my coffee!

Other Thoughts: This cooler does what it was designed to do! I've had 0 problems with it!

Pros: Great cooling, nice design. LGA2011 supported. Ran Prime 95 after install, and kept temps below 55C.

Cons: This unit is for 3 pin motherboards. If you have a 4 pin PWM motherboard, you need to purchase the 920 model. This is not spelled out in anywhere in the specs. Without PWM, the fan runs at high speed all the time. I had less noise with a traditional block cooler. Also, the installation instructions are worthless. Go to YouTube, people have posted videos on how to properly install. These are the reasons I took off two eggs.

Other Thoughts: Note, if you have a LGA2011 motherboard, you do not need the back bracket, you use the metal one on the board and the shorter screws that attach directly to it. Also, not in the installation instructions.
