Kúhler H2O 650 Liquid CPU Cooler

The Antec KÜHLER H2O 650 delivers high-performance liquid cooling for your CPU in a quick, easy-to-install package.

The Antec KÜHLER H2O 650 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 extra large pump circulates coolant through optimized water channels, while easy-bend flexible tubing allows the KÜHLER H2O 650 to be installed in nearly any orientation. In addition to easy installation, a powerful PWM fan pushes air through directional blades and channels it through the radiator for optimal cooling. Included in the box is an air duct that reduces static pressure which in turn, allows air to flow out of the case efficiently. Lastly, integrated firmware automatically adjusts fan speed and changes the RGB LED based on temperature. Engineered for maximum performance, the Antec KÜHLER H2O 650 delivers liquid cooling performance at an air cooling price

decent cooling

Disagree with above it can be abit fiddly but managed on my own fairly easy and cools great


Nighmare to install

I build PCs. I have installed loads of the older version and 5 of these.

Compared to its predecessor, this new version has gone out of its way to make the installation harder.

The inserts in the back plate are not as secure as the original and need temporary tape to hold them in place during the installation.

The holding bolts are now spring loaded and a lot harder to align and get the first turn on them. I now need someone to help me to install this. I use to be able to install these on my own.

From a kit that was a dream to install and very well thought out, i do not know what Antec were thinking with this.

I also get CPU fan alarm warnings every time i start a PC until the CPU has warmed up. I think the RPM on the fan runs in relation to the CPU temp so i have to wait at the BIOS screen until the fan hits 800 rpm before i can try to restart it.

Poor Poor Poor Design!!!!!!!
