I doubt that you care after a month, but it should fit. I'm using one on an X470 board from Asus.
On an AM4 board, it requires an adapter, which is included with current shipments of the cooler. You remove the stock lockdown brackets, and replace them with standoffs. The most difficult part of the whole process for me was replacing the original hold-downs on the cooler wit the AM4 adapter.
Do you have enough space in your case for the radiator? (I notice you're using a mictoATX board.)
