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 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 proces
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.

This kit is solidly built and created a good frame on my motherboard. However, I tested the cooling under cpu stress and it was barely working. I had to reseat the cooler 4 times and use a ton of thermal paste, and screw this in so tight that the mounting screws started threading. Bottom line is you might want to sand down the plastic risers a half millimiter in order to give you better contact with the cpu. Having to use so much thermal paste to ge the cooler to work within acceptable ranges means my cooler is not snug enough to cpu. Sadly, my motherboard is mounted now and I dont want to take it out to sand down the risers. I''ll just have to live with a .4ghz overclock.
