Antec KÜHLER H2O 620 CPU cooler Review

👤by Sahil Mannick Comments 📅16-08-11

Installing the Antec KÜHLER H2O 620 is exactly the same as the 920. The process is fairly straightforward thanks to the user manual but it can be fiddly due to the number of small components included in the mounting kit. In our guide, we will focus on installation on LGA1366 but the process is similar for other sockets.

1.) Choose the appropriate backplate for either AMD or Intel. The rectangular one is for AMD whereas the above is for Intel sockets.

2.) Insert the metal backplate inserts into the appropriate labelled holes for socket 77/1156/1155/1366.

3.) Attach the adhesive pads to the backplate.

4.) Install the backplate to the back of the motherboard making sure each corner has gone through the holes.

5.) Place the blue inserts into each corner of the retention ring making sure the clips are on the inside.

6.) Install the 4 mounting screws into the outer most holes of the inserts and line up the retention ring with the backplate on the front of the motherboard. Screw each corner in slightly so that they are in place but don't tighten them just yet.

7.) Install the CPU block in the retention ring and twist it so that it is latched onto the bracket. Once secured, tighten the screws on the retention bracket. Do not over tighten as it may damage the plastic inserts.

8.) Connect the fan cable to the extension lead and plug the pump cable into a fan header on the motherboard. Install the back fan and radiator using the 4 provided long screws.

Those familiar with earlier Corsair units will recognise the installation procedure as the process is exactly the same here using the same kit. All the Asetek units will be compatible with one another. A major downside that I observed is that the screws don’t give any feedback as when to stop turning unlike spring-loaded ones that merely stopped as soon as enough pressure is put through. The problem is that screwing down too much can not only damage the blue retention clips but also flex the motherboard. In my case, it caused the first DIMM slot to stop working until I loosened the screws. Another complaint is that it can be a pain to hold the radiator while trying to feed the long screws through the fan and to the radiator when installing the unit to the case.
