The second radiator is more interesting:
This is in fact the same thing, but two times larger and without fan speed control. That’s why there are low-speed fans here with a max rotation speed of 1300rpm. The fittings are turned around to the fan side.
This is done for the sake of convenience during transportation. You can easily put the fans on the other side if you want to.
I guess this radiator can only be easily installed in the system case if you’ve got a Gigabyte Aurora, the only PC case with a seat for two 120mm fans at the back panel. For other users, the kit includes two aluminum feet:
These are secured on the radiator with long screws:
The fastening isn’t very good. The feet don’t have proper contact with the fan grids and wobble a little even if you fasten them tight. Considering the desktop orientation of the radiator, it is better to turn the fittings backwards:
In this case, the pipes at the back won’t spoil the overall picture.
Now I will discuss the nuances of assembling and will test these kits.
