You'd be mistaken, Intel hasn't had a clip mounting system since socket 370 P3 days. Even P4 on 423 had 4 corner mounting systems and all of the Intel systems had them since.

The cheapo aluminum coolers from Intel always had that rotated design to get a little bit more surface area in the same volume. With the age of this system Intel had copper pucks in the middle of their heatsinks. It wasn't till later they went full aluminum. This is very clearly an AM4 motherboard as seen by the mounting.

Like the other commenter pointed out, it's an A320M-C board, it says right on it.

Yeah, you're right. I was looking at the fin layout, but forgot to check the mounting system.
