Noctua NM-I3 Intel Mounting Kit for LGA775, 1156 and 1366

The NM-I3 SecuFirm2™ Mounting-Kit makes all Noctua CPU coolers compatible with Intel’s LGA1156 & LGA1366 sockets for Core i5 and Core i7 processors. Designed to combine outstanding reliability, optimal contact pressure and easy, straightforward installation, SecuFirm2 is an enthusiast-grade mounting system that meets the highest demands in safety, performance and ease-of-use.

NM-13 Mounting Kit

Ultimate Reliability

Noctua’s SecuFirm™ mounting systems are renowned for their excellent reliability, minimise the stress on mainboards and make it possible to transport the system without uninstalling the CPU cooler. With tens of thousands of units sold, there’s not a single known case of failure.

Backplate with Screw-Threads

SecuFirm2™ utilises a backplate with screw-threads that simply installs on top of the stock LGA1366/LGA1156 backplate. Not having to remove the stock backplate significantly reduces overall installation time and eliminates the risk of damaging the CPU socket. Thanks to the screw threads, the backplate can’t slip during the installation process.

Integrated Fastening Brackets

Fully integrated fastening brackets with fixed pressure screws and springs greatly facilitate the installation process. No more fiddling with screws and springs!

Maximum Convenience for Enthusiasts

Thanks to the use of separate mounting bars, uninstalling and reinstalling the cooler only takes two screws. Loosening two thumbscrews gives full access to the socket without the backplate falling off, making it a child’s play to change CPUs even if the mainboard is installed inside a case.

Backwards Compatibility

SecuFirm2™ is fully backwards compatible with all Noctua coolers since 2005, making them safe long-term investments that can be used for several CPU generations.

PLEASE NOTE: Owners of Noctua CPU coolers can obtain the NM-I3 Mounting-Kit free of charge via Noctua’s website. Proof of purchase (photo, scan or screenshot of the invoice) of both a Noctua CPU cooler and either a socket 1156/1366 mainboard or socket 1156/1366 CPU are required.
