Noctua NM-i17xx-MP83, Mounting Kit for Noctua CPU Coolers on Intel LGA1851 and LGA1700

The Noctua NM-i17xx-MP83 is a mounting upgrade kit for users who want to install a compatible Noctua CPU cooler with an 83 mm mounting pitch on an Intel LGA1851 or LGA1700 motherboard; check Noctua’s compatibility information for the specific cooler.

Recommended For

• PC builders moving to Intel LGA1700 or LGA1851 who want to keep using an existing Noctua cooler, rather than replace the heatsink, provided it uses 83mm mounting pitch and is listed as compatible.
• Owners of older compatible Noctua coolers who are upgrading their Intel system and want to extend the cooler’s use across another CPU generation.
• Builders who need the LGA1700/LGA1851 mounting hardware for a compatible 83mm-pitch Noctua cooler; the kit provides a dedicated backplate and mounting parts for that upgrade.
• PC builders who want the option to rotate a compatible Noctua cooler by 90 degrees for airflow or component-clearance reasons, after checking the fit of their specific motherboard and parts.

Real-World Use Scenarios

• When building an LGA1700 or LGA1851 PC, a user with a compatible Noctua cooler can fit this kit instead of replacing the cooler; the kit adapts the mount, but does not change the cooler’s cooling performance.
• When reusing an older Noctua cooler in a new Intel build, the user can install the matching backplate and mounting bars for the new socket, then follow Noctua’s installation guide to attach the cooler.
• Before buying the kit for a cooler upgrade, the user should check Noctua’s compatibility information for the cooler’s 83 mm mounting pitch; a cooler with 78 mm pitch needs the MP78 kit instead, so checking avoids a mounting mismatch.
• When a cooler’s default direction conflicts with nearby parts, the user can try mounting it 90 degrees rotated; whether that works depends on clearance around the socket and other components.
• When repairing or refreshing a compatible LGA1700 or LGA1851 system, the kit provides the socket-specific mounting hardware needed to keep using the Noctua cooler, provided the cooler itself is compatible and in working condition.
