Cooler for Intel LGA 1700 and AMD AM4

The NH-U12S is a single-tower air cooler bundled with an NM-i17xx-MP78 upgrade kit that adds native support for Intel LGA 1700 processors including 12900, 12700 and 12600 series CPUs. The package also covers AMD AM4, AM3, Intel LGA 1200, 115x and 20xx sockets, making it a broad multi-platform solution. It targets builders who want quiet thermal performance across current and next-generation desktop platforms.

Check socket clearance and motherboard layout

Verify compatibility with your specific LGA 1700 motherboard through the Noctua Compatibility Centre before ordering, as individual board layouts may affect fit. The 45 mm slim profile guarantees 100 percent clearance for tall memory modules, but surrounding components such as VRM heatsinks or PCIe slots should still be inspected. Ensure your case provides sufficient height for a 12 cm tower cooler and that the mounting holes match the SecuFirm2 pattern.

SecuFirm2 mounting and NF-F12 focused-flow fan

The proven SecuFirm2 system delivers secure, tool-friendly installation across all supported sockets without backplate removal on most boards. A premium NF-F12 PWM fan provides automatic speed control for low-noise operation under varying loads. Included NT-H1 thermal compound and a six-year manufacturer warranty reflect the build quality expected from a cooler that has earned more than 400 awards.

Questions about this item

Does the NH-U12S box include the LGA1700 mounting kit or must it be purchased separately?

The bundle ships with the NM-i17xx-MP78 upgrade kit inside the box, so the LGA1700 hardware is already included.

Which Intel socket version should I select for a Core i7-12700K build on a Z690 board?

Choose the LGA1700 mounting hardware supplied in the NM-i17xx-MP78 kit; it supports the 12700K and other 12th-generation Core i9, i7 and i5 processors.

What does the 45mm slim profile mean when the cooler is installed in a real system?

The 45mm depth guarantees 100% clearance for tall RAM modules, so memory height will not block the fan or heatsink.
