Owners of older Noctua CPU coolers who wish to upgrade to the upcoming LGA1155 socket will be able to obtain the appropriate NM-I3 SecuFirm2 mounting kit free of charge, Noctua announced today. Recent models such as the NH-C14, NH-D14 or NH-U12P SE2 already include the NM-I3 mounting kit and are fully compatible with LGA1155 out of the box.

Due to the spacing of the mounting holes being identical on LGA1155 and LGA1156, Noctua's NM-I3 SecuFirm2 mounting kit for LGA1156 also supports Intel's upcoming 'Sandy Bridge' platform. The following Noctua coolers already include the NM-I3 SecuFirm2™ mounting system for LGA1156 and can thus be used on LGA1155 mainboards without any upgrades or modifications: NH-C14, NH-D14, NH-C12P SE14, NH-U12P SE2, NH-U9B SE2.

rs of older Noctua models that don't include the SecuFirm2 mounting system for LGA1156/1155 can obtain the NM-I3 kit free of charge on Noctua's website in order to make their heatsinks compatible with the new socket. A proof of purchase (photo, scan or screenshot of the invoice) of both a Noctua CPU cooler and either a socket 1155 mainboard or socket 1155 CPU are required.

The NM-I3 mounting kit is compatible with all Noctua retail coolers since 2005 and is also available in stores at a low service charge.
