Will the Noctua NH-D15 work with the MSI MAG B550 TOMAHAWK?
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.
