The LGA1366 SecuFirm2 Mounting-Kit makes all Noctua CPU coolers compatible with Intel's LGA1366 socket for 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. 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. SecuFirm2 utilizes a backplate with screw-threads that simply install on top of the stock LGA1366 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. Fully integrated fastening brackets with fixed pressure screws and springs greatly facilitate the installation process. No more fiddling with screws and springs! 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. 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.
