Q: Will the Cooler Master Hyper 212 Black Edition with LGA1700 (RR-212S-20PK-R2) work with the ASRock B550M Pro4?

Yes. It works. Read the notes below before buying. Sources: https://www.asrock.com/mb/AMD/B550M%20Pro4/index.asp#Specification, https://www.coolermaster.com/en-us/products/hyper-212-black-edition-with-lga1700.html, https://www.noctua.at/en/expertise/guides/amd-am5-all-you-need-to-know

Yes. Both use AMD AM4 cooler mounting (stock AMD backplate).

Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.

Why

✓ Both use AMD AM4 cooler mounting (stock AMD backplate).

Good to know

Low-profile coolers that replace the stock AMD backplate (e.g. Noctua NH-L9a-AM4, NM-AM4-L9aL9i kit) fit AM4 but not AM5.
Noctua notes some AMD boards violate AMD's 96x114 mm keep-out zone; check RAM and VRM-heatsink clearance with large coolers.
