Compatibility and Installation Tips
Corsair H70 cooling system is compatible with all contemporary platforms, including LGA1156, which is its indisputable advantage over the predecessor, Corsair H50. In fact, Corsair provided this total compatibility feature not by adding another retention kit for LGA1156 into the bundled accessories, but by making the existing LGA 775/1366 retention frame universal. The installation procedure is the same for all platforms and starts with sticking two adhesive strips onto a plastic backplate (hereinafter we are using Intel platform as an example):
After that threaded metal bushes are inserted into one of the three retention holes in the corners of this backplate:
Backplate is stuck to the bottom of the mainboard PCB.
The top retention plates can go with one of the two removable bushes with retention holes in them:
They are inserted into the loops on these plates:
After that the top retention plate is lightly attached to the backplate on the other side of the PCB using four retention screws. It is important to remember not to tighten the screws to the end at this point. After that you can install the mainboard into the system case and attach one of the fans with the radiator on the back panel of the case using enclosed retention screws:
As for the second fan, it is better not to install it until the processor water block is in place, because it will be in the way. You have to install the water block with the pump into the frame and rotate slightly, so that the retention loops on the frame could catch on to the water block stands. Only then you can tighten the screws evenly:
Now the only thing left to install is the second fan on top of the radiator:
Note that the fans are installed in such a way that they are sucking the air inside the case, which is the recommended position for maximum CPU cooling efficiency. However, there is also a different side to this picture. Yes, radiator will be cooled better by the airflow from outside, but the hot air from it will be pushed into the case and may increase the temperature of other system components, unless it is pushed outside quickly enough. Here it is important to remember that the default rotation speed of Corsair H70 fans is 1600 or 2000 RPM, so it may be a challenge to oust hot air outside the system case in time.
Anyway, we are going to test Corsair H70 cooling system in all possible modes in our today’s test session.
