Noctua has released updated versions of its NH-L9i and NH-L9i Chromax Black low-profile CPU coolers. These coolers often find their way into compact and small form factor (SFF) systems, and Intel 12th Gen buyers will be pleased to find that they now support the new LGA 1700 socket.
Although these coolers are very compact and only 37 mm in height, they are able to dissipate more heat than you might expect. According to Noctua CEO Roland Mossig, the NH-L9i is capable of spreading up to 160W. This means that you can not run a Core i9 12900K or Core i7 12700K at their full turbo power, although it is certainly possible to run them with some BIOS power adjustments.
A Core i5 12600K can be run without compromise thanks to its 150W maximum turbo power, but it is the SFF-friendly non-K CPUs that will be a better match. These are scheduled to be released in 2022.
Both the traditional Noctua two-color version and the all-black Chromax versions comply with Intel’s socket clearance guidelines, which means they will not interfere with your RAM or GPU.
In addition to the updated NH-L9i coolers, Noctua has released the NA-FD1 duct set. The set is made of EVA foam spacers, which can be stacked up to a height of 45 mm. It is designed to allow the fan to draw cooler air from outside the cabinet instead of reusing hot air that is already inside the cabinet. Noctua claims that this can lower the CPU temperatures by about 5 degrees Celsius.
The suggested retail price for the NH-L9i is EUR / USD 44.90. The NH-L9i Chromax Black is priced at EUR / USD 54.90, while the NA-FD1 channel set is priced at EUR / USD 12.90.
