The NM-M1-MP78 is a SecuFirm2+™ multi-socket mounting kit is an ideal upgrade for users who want to upgrade their Noctua CPU coolers to the new Torx®-based SecuFirm2+™ standard or the latest sockets not yet supported by their cooler at the time of purchase. The NM-M1-MP78 has been compatible with a variety of Noctua CPU coolers with 78-mm mounting pitch since 2005 as well as all current desktop platforms from AMD (AM5 & AM4) and Intel (LGA1851, LGA1700, LGA1200, LGA115x). The NM-M1-MP78 therefore offers an excellent, future-proof foundation for air-cooled premium builds. On AM5, the offset mounting option can significantly improve performance and typically reduce the CPU temperature by 1 - 3°C. Caution: Please note that the NM-M1-MP78 set is only compatible with radiators with a mounting pitch of 78 mm. For radiators with a 83-mm mounting pitch, the NM-M1-MP83 set must be used.
