Good to know
  • Noctua: AM4 and AM5 share the same stack-up height and backplate thread pattern, so coolers that use the standard AMD backplate carry over; Corsair likewise says AM5 uses the same cooler bracket size as AM4.
  • Exception: coolers that replace the AMD backplate (Noctua NH-L9a-AM4, NM-AM4-L9aL9i) cannot be fitted to AM5.
  • Older Noctua coolers without AM4 hardware need the NM-AM5/4-MP83 or NM-AM5/4-MP78 kit (free with proof of purchase).
  • Offset mounting bars (e.g. Noctua's AM5 offset bars) are optional accessories that shift the heatsink toward the CPU hotspot; they are not required for fitment.
  • Cooler Master Hyper 212 Black Edition (RR-212S-20PK-R2): AM5 brackets are included only in later production; some units ship without them.
  • Low-profile coolers that replace the stock AMD backplate (e.g. Noctua NH-L9a-AM4, NM-AM4-L9aL9i kit) fit AM4 but not AM5.
