The Antec KÜHLER 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 pre-filled and requires no maintenance. The voltage-controlled 120mm fan and 3rd generation copper coldplate ensure efficient cooling, while the estimated 50,000 hour pump lifetime means this cooler is even likely to outlast the system it cools. Lastly, easy-bend flexible tubing allows the KÜHLER H2O 620 to be installed in nearly any orientation. Take your PC's Quiet Computing to the next level with liquid cooling performance at a price that rivals aftermarket air coolers.

5 out of 5 eggsKeeping things cool! It's TOO easy!

Pros: Keeps my CPU cooled when I'm boosting OR at regular temps! Allows for better airflow to the rest of the other components by not have a clunky fan blocking everything

Cons: Not the easiest to install. Make sure you watch a video and read the instructions. Maybe practice what you need to do before applying the thermal paste and giving it a go

Other Thoughts: This product (or similar) is a MUST buy when building a PC

5 out of 5 eggsSo far, a very good product.

Pros: Easy to install, keeps things cool. Seems well built. The hoses are beefy enough that they could be used in automotive applications.

Cons: None whatsoever.

5 out of 5 eggsKuhler 6220

Pros: Great cooler, Easy to install. Keeps my i7 3770k ice cold never seen the cpu over 40 degrees celcius as of yet. I dont do much overclocking or tweaking however i definitley wanted a better cooler in case i wanted to. I primarily play mmorpg's such as warcraft and starcraft and occasionally old school RTS like Age of empires

Cons: none

Other Thoughts: many people have complained about the installation process however i found it to be rather simple and straight forward. The instructions were easy to read and follow so long as you have half a brain

5 out of 5 eggsAmazing

Pros: For something I bought intending to flip, it has done nothing but impress. Has keep both an i5-3570K and i7-3770K running at a cool 75C while over clocked.

Cons: After 1 year, the motor has started to make a little noise.

2 out of 5 eggsSo so

Pros: Easy to install if you take a bit of time and patience, it is very quiet.

Cons: Doesn't cool the AMD FX-8120 Zambezi 3.1GHz Socket AM3+ 125W Eight-Core Very well at all.
At room temperature it will over heat without over clocking even. I resorted to restricting my CPU to 85% power with windows power management, and it died after 14 months of use. I like Antec power supplys but I think I'll go with more mainstream brands for coolers in the future.

4 out of 5 eggsWorked Great for 1 yr before failing

Pros: Incredibly Quiet, Kept CPU cooler than any other fan/heatsink combo I have ever used. Easy to install, looks great did I mention how quiet it is?

Cons: only lasted 1 yr before liquid pump failed

Other Thoughts: I highly recommend liquid coolers - They keep the CPU amazingly cool and are super quiet. Even though it failed I liked it so much I am buying a new replacement of the same type

4 out of 5 eggsgood

Pros: owned it for over a year now and keeps my temps are cool and constant only 10c variation from idle to full load (most of the time)

Cons: with my old 125 quad core Phenom II temps where abit to high low 40`s on idle and high 50`s under load ( sometimes as high as 62c) But with my new AMD 6300 @ 4.2GHz it never gone past 45c and on idle it`s about 25c

2 out of 5 eggsBeware of newer revisions...

Pros: Quiet and decent cooling when it works....
See below

Cons: I bought this cooler last year and it was working fine, then all of a sudden pump died so I RMAed it. Ever since then after 3 RMAs I can not get a product that functions correctly. You see asetek makes these coolers for Antec. I seem to now have v4 of the 620. And the one thing I notice which proves it is not up to par is the surface is NOT flat, its what they called "bowed" which means not good contact with CPU surface which leads to insanely high temps.

Other Thoughts: RMAing again
