Ultimate Reliability
Noctua's SecuFirm™ mounting systems are renowned for their excellent reliability, minimize 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™ utilizes a backplate with screw-threads that simply installs on top of the stock LGA1366/LGA1156/LGA1155 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.

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!
