The NH-L12S is the second generation of its predecessor NH-L12. CPU cooler with a very compact low-profile design allows it to be mounted in dense SFF and HTPC cases with excellent cooling efficiency and NOCTUA’s reputable low noise performance. It’s fan allows it to be mounted on top or underneath the heatsink allowing it to have a ram clearance of up to 48mm or maximum height of the cooler to be only 70mm. It is especially suited for sandwich-style or console-style ITX cases. Thanks to it’s mounting system it is suited for a variety of CPU-sockets.

Intel’s new 12th generation Core processors (Core i9-12900K(F), Core i7-12700K(F), Core i5-12600K(F), etc.) are based on the entirely new LGA1700 socket. Due to its different mounting hole pattern and stack-up height (height of the CPU and socket combined), LGA1700 requires a new mounting mechanism for CPU coolers.Noctua is in the process of updating most of their multi-socket CPU cooler models to include LGA1700 mounting hardware. Please see their ‘timeline of Noctua coolers to include LGA1700 mounting hardware’ to check which model will be updated when, and this FAQ for how to verify if your cooler already includes LGA1700 mounting hardware.For coolers that do not yet include LGA1700 mounting hardware, Noctua offers a direct free-of-charge mounting-upgrade kits (NM-i17xx-MP83 for coolers with 83mm mounting pitch and NM-i17xx-MP78 for coolers with 78mm mounting pitch). Please see this FAQ to check which kit is required for your cooler.A proof of purchase of both an eligible Noctua CPU cooler (i.e. invoice) and either an LGA1700 CPU or an LGA1700 motherboard is required for ordering the kits free of charge via Noctua's website.More information can be found on Noctua's website HERE.
