With more than 200 awards and recommendations from international hardware websites and magazines, the original NH-L12 was one of the most successful low-profile CPU coolers ever built. With its top 120mm fan removed, it also proved to be an ideal choice for low-noise setups in the Ghost S1 chassis.

Coming with a single 92mm fan, Noctua’s second generation NT-H2 thermal compound as well as the latest SecuFirm2™ multi-socket mounting system, the NH-L12 Ghost S1 Edition has been customised to be an ideal companion for quiet high-end builds in Louqe’s award-winning Ghost S1 enclosure.

While the large NH-L12 heatsink extends beyond the socket zone and will overhang the RAM slots in most configurations, there is plenty of space underneath, so it is compatible with RAM modules of up to 48mm height.

The NF-B9 92mm fan supplied with the NH-L12 Ghost S1 Edition supports PWM for convenient automatic speed control through the motherboard: Full performance under load, virtually silent at idle! In addition, maximum fan speed can be reduced from 1600 to 1300rpm using the supplied Low-Noise Adaptor for even quieter operation.

Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA1851, LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) as well as AMD AM5 and AM4 (since 2019), the SecuFirm2™ mounting included with the NH-L12 Ghost S1 Edition is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use.

Thanks to Noctua’s SecuFirm™ ecosystem, the NH-L12 can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets, which makes the NH-L12 a safe long-term investment.

For high-end builds in compact cases, every degree counts. This is why the NH-L12 Ghost S1 Edition includes a tube of Noctua’s next-generation NT-H2 compound that provides even better performance than the award-winning NT-H1, allowing you to achieve the best possible cooling results.

With many heatsinks, the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance. By contrast, the NH-L12’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage.

Noctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy, the NH-L12 heatsink is built to last, and like all Noctua fans, the supplied NF-B9 unit features an MTTF rating of more than 150,000 hours. The entire package comes with a full 6-year manufacturer’s warranty.
