The user guide shows us how to perform the installation, depending on the socket:

Two plastic back plates are offered, one for AMD systems and one for Intel, along with two fixing mechanisms; in the bags we can find some long screws to mount the fan/radiator onto the case, plastic blue/green colored adapters that must be installed on the top mounting metallic rings, necessary screws and the nuts that must be inserted into the plastic back plates; to aid the installation procedure, we can also find two adhesives that can be used to secure the plate on the back of the motherboard:
