For Noctua coolers with 83mm mounting pitch
The NM-AM5/4-MP83 kit is compatible with a wide range of Noctua CPU coolers that use 83mm mounting pitch, whereas heatsinks with 78mm mounting pitch must use the MP78 version. Please refer to our detailed compatibility information to check which kit is right for your cooler.

Trusted SecuFirm2™ quality
Over the years, SecuFirm2™ has become synonymous with impeccable long-term stability and flawless craftsmanship. Enthusiast users and industry clients alike trust the time-tested quality of Noctua's professional mounting systems.

Perfect contact pressure
SecuFirm2™ mounting systems use high-grade coil springs to achieve perfect contact pressure. No guesswork regarding how far to tighten the mounting screws, no risk of damaging the socket with excessive pressure!

Standard AMD backplate
Minimising unnecessary waste and facilitating the installation procedure, the NM-AM5/4 kits install to the stock AMD backplate that is pre-installed on the motherboard.

Tailor-made for AM5/AM4
Aiming to cut costs, many manufacturers use cross-platform parts for both AMD and Intel, which can cause compatibility issues. Noctua’s SecuFirm2™ mounting system for AM5 and AM4 has been tailor-made for these sockets in order to ensure optimal compatibility and ease of installation.

Backwards compatibility
Noctua CPU coolers are renowned for being safe, long-term investments that can be used for several CPU generations. Accordingly, even coolers that are 15 years or older can be upgraded to the latest AMD Ryzen platform using this mounting kit.

Sustainability
Using a CPU cooler across several platform generations instead of buying a new heatsink for each generation is not only economical, it also helps to reduce unnecessary waste and save precious resources. By upgrading rather than replacing your cooler, you’re actively contributing to a more sustainable PC industry.
