What is a mounting adapter?

[kimmikkopls]

Hello! I am looking to upgrade my cpu,motherboard and cpu fan.

I listed the items I wanted in pc part picker and says they are compatible but it gives me this message:

The Cooler Master - Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler may require a separately available mounting adapter to fit the MSI - A320M PRO-VD PLUS Micro ATX AM4 Motherboard.

What does it mean exactly?

If it is a new cooler (made in the past year) it will have the AM4 kit included.

So will this have it?

It most likely will but one cannot be 100% sure.
