Cons: cpu mount would be a little hard to install for novice users as the instructions are not clear.
Pros: super quietincredible air flow Comment:
This is an excellent cooler. The noise that all of you are having is air stuck in the pump. Once you have an air lock it will not go away by it own. Here is what I did power up the unit before you install it hold the CPU cooler lower than the radiator and make sure that you radiator hose are facing down not up . Next shake the CPU unit while it on you will hear the air pass the tubes and it will be instantly quiet. Also when mounting it to your case make sure that your radiator is higher than your pump. Once the air is out its super quiet. Fans are only loud when in max setting. I play borderland 2 and bfbc2 and they are only turning at 700 to 800 rpm keeping my temp to 32 deg c. very quiet |

Cons: Seems very prone to problems and noise - had two units that needed to be returned for replacement. I question the build quality (or I just had terrible luck, twice)
Pros: Fairly easy to install, had good temps when it was working properly Comment:
I had to send my H2O 920 back to Antec twice. With my first unit, the hose started to leak about 4 months after purchase. They told me it was a defective hose with a weak spot. The second (replacement) unit had a significant amount of pump noise that started after about 3 months, and got continually worse. This time, it was a defective pump unit. They told me it was still under warranty, and they would replace it. While I love the fact that they stood behind their product, Antec does not have a supplier in Canada that will offer a replacement prior to them 'checking' your unit (advanced rma they called it). So, I was forced to ship it to Ontario, wait for it to be checked and confirm it was a malfunction, and they sent out a replacement. The turn-around was about 2 months total. Meanwhile, I was forced to go through replacing the cooler with the stock intel unit twice, and back to the 920 when it got shipped back to me, which is a bit of a pain. After the second broken unit, I gave the replacement unit to a friend for free and upgraded to a Swiftech H220. |

Cons: Like Terence_H the noise from the pump was excessive to say the least
Pros: Great job of cooling Comment:
I ended up removing the unit. I fired it up with a spare psu and tried as Antec suggested, shaking it to remove air from the pump. I then reinstalled it using Arctic silver 5 with the pump hoses at the top and the rad hoses at the bottom to keep air out of the system. It did reduce the noise, not completely but to a point that is tolerable. |

Cons: Pump (often noisy if you get one from a bad batch), instructions are like hieroglyphics
Pros: Price (When on sale), Size, Look Comment:
Firstly, let me preface this by saying that Antec is a great company. This, however, is a bad cooler.The issue with the bad pump noise is sometimes due to a "bad batch", but do a basic Google search and you'll see that the product was designed with air bubbles (though necessary) that are expected to cause this problem at times. I'm disappointed that a company like Antec would push out a product without having tested it more thoroughly and worked out the kinks.The instructions. You know how Ikea has wordless, completely pictographic instructions that even a child can follow? Well, imagine not having words, but only horrible diagrams that skip key steps. Not much more to say. Again, I just expected more from Antec.Finally, if you do get a defective product, make sure you RMA through Antec rather than the retailer. Antec RMA even suggests this as retailers will probably just replace you product with another from the same "bad batch".All in all, if you can get this on sale, and manage to get a pump without defects, it would be e decent product. I even managed to configure mine in a Fractal Design Node 605 by converting the airflow of the case from one side to another - right to left, instead of in the front and out the back fan vents on either side. |

Cons: none
Pros: Steady temperatures loadedLED looks greatEasy to controlQuiet Comment:
I installed this on my AMD FX-8350 CPU, and running loaded with two monitors, FarCry 3 on ultra, along with multiple applications on the second monitor, it still runs at 42 degrees. The software that comes with it is very helpful, and allows you to change the color of the CPU heat sink LED. It's very quiet and looks great inside the case. It never took up too much room, mind you I'm using a full tower case. Be cautious if buying for a mid-tower case, it could cause problems. |

Cons: seems I got one with bad USB interface, everything worked except the USB software control. did RMA through antec and expecting new unit back in a day or so.
Pros: very compact and appears well put together. relatively easy to install (tho I had to pull mobo for backplate) and easily dropped my cpu temps by 20C even under load. antec was great about retaining ring for 775, not sure how long they will continue this though. Didn't have any issues with pump noise, and fans are quiet on low speed, but it is loud when they are ramped up full speed. Comment:
overall, well worth the price, especially when on sale for $70. super easy watercooling for those who want a bit better than air and not wanting to get into a custom solution for whatever reason. I've had good support and service from both NCIX and Antec, thanks guys! |

Cons: Nothing
Pros: Silent, Efficiency, Del Light Comment:
My first purchase of water cooling and I'm really disappointed in the efficiency of it. Very quiet, aesthetical, and compact. Fit in a case Mid-Tower-35 Antec Darkfleet. I totaly Recommended. |

Cons: Fan very loud on Extreme setting, recommend using Custom fan settings.
Pros: High Quality, Performance, Very quiet on idle to low CPU usage. Comment:
This is a great product for those wanting to give liquid cooling a try. Since this is an enclosed liquid cooling solution, you have little to worry about in terms of pouring liquid or damaging your components. Everything comes pre-assembled, you just need to mount it correctly and you're good to go.Great cooling for overclocking on a push/pull configuration, far superior over just using an air cooler/heatsink. |

Cons: Was a bit of a pain to install.
Pros: Customizable LED "Antec logo" light.Keeps temps low, even under load.Runs silently. Comment:
I've owned this for about 2 months now and have not had any problems. The Kuhler has been a great purchase for anyone who's interested in just keeping the cpu nice and cool or if you're interested in overclocking while keeping temps at a moderate rate. I highly suggest for anyone who's interested in using a water cooling set up. |

Cons: - So loud at "Extreme" mode.- My Hyper220 CPU heatsink kept my processor at 11C idle, the H20 920 does the same on "Extreme" which is way louder.
Pros: - Keeps my AMD 8-core cool enough m 5ghz.- Looks nice.- on "silent" mode it keeps my processor at 30C.- "Silent" mode is actually silent.- You can change the light on the cooler to custom colors (RGB) Comment:
Does it's job. With custom fan settings I car rarely hear it when gaming. |

Cons: Went a little bit crazy and snapped the little clips for holding it down. :P
Pros: Great cooling! Best I've had so far! Comment:
I put this on my Core 2 Quad Q9650, temps went from 70c at load on the default cooler all the way down to thirty. During idle, I'll see cores at 28 degrees Celsius! Load temps, overclocked to 3.8Ghz have so far not passed the 48 degree threshold.I haven't owned this puppy long... But it is awesome. I'll be burning it in within the next week or two. :) |

Cons: Pricey if not on sale.
Pros: Keeps CPU super cold.Quiet. Comment:
This is a great cooler. I at normal loads(40%) OC'ed to 4.5GHz my system runs at about 35C. This is a huge improvement as my ivy bridge i7 typically ran about 40C at idle on the stock cooler without any OC! Even with stress tests it barely reaches 70C. However, unless you get this really cheap like I did on boxing day, this cooler gives you only marginal improvements over lower models which are a 1/4 of the the reg price. This unit is also a bit tricky to install into a standard ATX case due to the large radiator. However, this obviously isn't a design flaw it just takes some skill. |

Cons: -Screws are not nearly long enough and wont thread the entire length needed and in addition have a small head so you may need to use an included washer which would make the problem even worse.-No longer gets detected in Windows-Complicated instructions and difficult to install without a helping hand.
Pros: -Good at cooling Comment:
Once the product is installed properly it provides good cooling and the software is okay as long as it's working.However, during installation the major pains are that the screws are not nearly long enough and wont thread the entire length needed and in addition have a small head so you may need to use an included washer which would make the problem even worse. The instructions are unnecessarily complicated and lacking in information. Antec has put a lot of faith into getting their consumers to figure things out for themselves. and difficult to install without a helping hand.After only 2 months from the date of purchase the device no longer gets detected in Windows and shows up as an Unknown Device which seems to be a common occurrence from a quick search online. Therefore the software for controlling and monitoring the cooler no longer works. |

Cons: - Terrible pump noise.- Difficult to install. Instructions are not as clear as they probably could be.- DON'T USE THE STICKY PADS THAT COME WITH IT TO INSTALL. It will be a nightmare to remove later should you choose to do so.
Pros: - Nice looking.- Color-changing light on the pump is a neat but unnecessary feature. Comment:
Please read this before buying:I very rarely review products but I felt compelled to maybe save someone else from my frustration. There is something wrong with the pump on these things. It makes a high-pitched "squealing" noise when the cooler is running pretty much anywhere between the lowest and the highest setting. It is(was) by-far the loudest thing in my computer. Before you say "Well I've owned this for XX months and it works fine", bear this in mind: I spoke to an Antec rep over the phone recently who, after hearing me only begin to describe the problem, stopped me and said that he knew exactly what I was talking about. He said that Antec had sent out a "bad batch" of these to retailers and suggested I RMA through them instead of NCIX since I would likely get another broken one and they would test it before sending it out. I'm inclined to believe him since at that time I was already on my second one from NCIX and both had the exact same issue.There is, of course, the chance that you won't get a bad pump. I'm sure they've fixed the issue by now since they acknowledge it. But the "bad batch" is still being sold. Buyer beware, it's really not worth the headache. Especially at this price. Save your time and money. Look for another cooler. |

Cons: Akward hoses, can be loud even if speeds are moderate.
Pros: Looks great, low temps, silent when on lowest setting, high CFM Comment:
Fairly easy install, a little tricky to get it to lock into place without making a mess. I used my own thermal paste and seen temps go from 70C on Core i7 2700k OC to 4.5Ghz down to about 50. Seems pretty hard to max out, holds its own against an H100 in my own opinion for most chips. |

Cons: Makes a weird noice, it has to do with the pump, I have RMA'ed it and the new one is still doing it. Odds are you won't hear it unless the room is silent, but it's annoying.
Pros: Great Cooling Comment:
Great cooler, especially with after-market fans, however the pump is messed up. If you search youtube for Antec 920 pump noise you will see what I mean. I have had two units and they both make the noise on and off. |

Cons: installation is a bit tricky, especially with the vague instructions. Also the wires run off the block instead of the radiator so its hard to keep the few wires off the mobo. Not a big deal, but looks sloppy.
Pros: cool, quiet, rgb led Comment:
Pretty decent cooler, does its job well and quietly. The only real problem i have with this cooler is that installation process is difficult. I suggest removing the intake fan, and the first RAM chip before installing the block, then after it is fitted down, out the ram back in and attach the fan. |

Cons: - Installation is probably the worst I have ever come by.
Pros: - Great Cooling- Included software to control fans and LED- Silent (except in Extreme mode) Comment:
I am giving this product a 4 star rating. The performance is great, the installation process is just stupid.My case is a Antec 550D. The screws provided by Antec were to short to fix the fans and radiator to the back of my case. I had to buy 1.5 inch 6-32 screws at my local hardware store. Ridiculous.The instruction manual was written by chimps. One of the most important steps (how to fix the cooling plate to the cpu) is completely skipped and the manual does not even mention one of the included pieces that has to be used (had to look it up on youtube).After several hours of fiddling and frustration. I was finaly able to boot and noticed temps not over 32C idle and always under 60C under load (prime95). This is with a small overclock (4.2Ghz) on a i5-2500K |

Cons: Big, but not "in your face Big"
Pros: Amazing cooling, dead quiet, and good software Comment:
Out of the 3 liquid cooling units i have installed lately, this has been my favourite. Much quieter than the others. The only change I would like would be how the fans are controlled, if you're trying for a very clean look, it's hard to hide the fan wiring because they run off the pump. |

Cons: radiator is too bulkyfan connector are too shortinstruction need improvement.
Pros: does cool down cpu and works very wellnice adjustable lighting on pumpnot too noisy Comment:
I have own this liquid cooler for 2 month now. In general it's good stuff. It does the job, normal mode on idle 3770k oc cpu, cpu stays 36-37 c. If fan goes extreme, under 3dmark high 3d test cpu stay a bit over 40c. Of course in exteme mode, the cooler makes horrible noise, but otherwise in normal mode, noise is quite acceptable. Change light on pump is cool, but other competitor are doing same. Now comes cons. The design to choose switch time radiator is not best choice. The single radiator is bulky, plus two fan keep it in between, they go together very thick, block view of board underneath even in full tower case. Maintainence work around that area is hard. Comparing to crosair h100, two thin raditor design, H2O 920 comes short.The fan power line is very short, go behind case is impossible, even though usb cable is long enough. Instruction need improvement. I am very experienced to assemble pc. But still doubt it's right or wrong after seeing the back mount bracket makes a strnage angle (not parallel) to LGA 1155 socket. I had to good some pictures to double chk. |
Bought this cooler for $50 to replace a Kuhler 620 that wasn't working well. Software that comes with it is useful to monitor the pump speed and liquid temperatures.
