NM-i17xx-MP78 mounting-kit
The NM-i17xx-MP78 is a SecuFirm2™ mounting upgrade kit that allows Noctua CPU coolers with 78mm mounting pitch (see detailed compatibility information) to be upgraded to Intel’s latest LGA1851 platform, as well as the previous LGA1700 socket. True to the SecuFirm2™ tradition, it combines outstanding reliability, optimal contact pressure and easy, straightforward installation in order to enable Noctua users to continue using their heatsinks on Intel® Core™ and Core™ Ultra series processors.
Caution: This mounting upgrade kit makes it possible to install a Noctua heatsink, which has originally been designed for other sockets according to their specifications, on LGA1851 and LGA1700 hardware. As the clearance specifications for LGA1700/LGA1851 differ from other sockets, it is crucial to verify that your heatsink is fully compatible with your LGA1700/LGA1851 motherboard before installation. Please consult our compatibility database in order to make sure that your motherboard is fully compatible with your heatsink. Noctua cannot be held responsible for any damage or losses caused by compatibility issues.
Please note that the NM-i17xx-MP78 is only compatible with heatsinks that have 78mm mounting pitch (see detailed compatibility information) and that the NM-i17xx-MP83 kit must be used for heatsinks with 83mm mounting pitch.
In line with Noctua’s policy of supplying customers with its premium-class SecuFirm2™ mountings free of charge, owners of eligible Noctua heatsink models can order the NM-i17xx-MP78 for free via this form. Proof of purchase (electronic version, photo, or scan of the invoice) is required for either an eligible Noctua CPU cooler with a compatible LGA1700/LGA1851 motherboard or an eligible Noctua CPU cooler with an LGA1700/LGA1851 CPU. Depending on the country, express shipping options may be available but are subject to service charges.
The NM-i17xx-MP78 SecuFirm2™ mounting kit is also be available for purchase at some of our resellers at a suggested service charge of EUR 8.90/USD 7.90. If you need the kit urgently, please consider ordering it via a local reseller or using the paid express shipping option.

Details
For Noctua coolers with 78mm mounting pitch
The NM-i17xx-MP78 kit is compatible with a wide range of Noctua CPU coolers that use 78mm mounting pitch, whereas heatsinks with 83mm mounting pitch must use the MP83 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!
One-piece backplate with fixed struts
The NM-i17xx kits feature a sturdy one-piece backplate with fixed struts that doesn’t require any pre-assembly or adjustment. Due to the fixed struts, aligning the backplate and attaching it to your motherboard is a breeze!
Tailor-made for LGA1851 and LGA1700
Aiming to cut costs, many manufacturers use cross-platform parts for both Intel and AMD, which can cause compatibility issues. Noctua’s SecuFirm2™ mounting system for LGA1851 and LGA1700 has been tailor-made for this socket in order to ensure optimal compatibility and ease of installation.
Cooler can be installed turned by 90°
Installing a cooler turned by 90° can be desirable for airflow or compatibility reasons. Thanks to the square layout of the hole pattern on LGA1851 and LGA1700 platforms, this is easily possible with the NM-i17xx kits if space and other components permit. However, please note that since the heatsink contact surface is optimised for standard orientation, rotating it by 90° may lead to a slight reduction in performance.
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 8 years or older can be upgraded to the latest Intel Core 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, but 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.
