While most Noctua heatsinks support Intel's Skylake's LGA1151 socket out of the box, Noctua has confirmed that older models can be upgraded with the NM-i115x kit at no additional cost. "With Skylake just around the corner, we're pleased to announce that we'll extend this offer for LGA1151. Owners of older Noctua retail heatsinks that don't support LGA1151 out of the box will be able to upgrade to the new socket free of charge," said Mag. Roland Mossig (Noctua CEO).

Due to the spacing of the mounting holes being identical on LGA1150, LGA1151, LGA1155 and LGA1156, Noctua's previous SecuFirm2 mounting systems for LGA115x also support Intel's upcoming 'Skylake' platform. All current Noctua coolers already include SecuFirm2 mounting systems for LGA115x and can thus be used on LGA1150 mainboards without any upgrades or modifications.

Users of older Noctua retail models that don't include a SecuFirm2 mounting system for LGA115x can obtain the NM-i115x kit free of charge on Noctua's website in order to make their heatsinks compatible with the new socket. The NM-i115x kit is compatible with most Noctua retail coolers since 2005.

To order the NM-i115x kit, a proof of purchase (photo, scan or screenshot of the invoice) of both an eligible Noctua CPU cooler and either an LGA115x mainboard or LGA115x CPU are required. The NM-i115x mounting kit is compatible with most Noctua retail coolers since 2005 and is also available in stores at a low service charge.
