Noctua launches NH-L9i for base LGA 1700

Small, compact computer builds usually mean the need for cooling solutions model smaller, something Noctua offers in the form of the almost ten-year-old model NH-L9i. It is a compact low-profile cooler that even with a fan mounted is only 37 millimeters high. The model has been launched in several variants, including a Chromax Black version.

Now Noctua is launching the model with adjustments for base LGA 1700, where Intel for the first time since socket LGA 775 changed the dimensions of its processors. The twelfth generation Core processors in the “Alder Lake” family have both grown in size and received different placement of the mounting holes on the motherboards. To cope with this, Noctua has equipped the revised version of the NH-L9i with the mounting system “Secufirm 2” which is adapted to the new dimensions.

We’re very happy with the performance of the NH-L9i-17xx coolers on Intel’s new LGA1700 CPUs. We have managed to dissipate up to around 160 W on the Core i9-12900K, pushing it to over 4.2 GHz, and up to 125 W on the Core i5-12600K running at 4.3 GHz. – Roland Mossig, VD på Noctua

The included fan is Noctua’s NF-A9x14 with PWM support and there are no major differences compared to previous revisions. According to Nocuta’s CEO Roland Mossig, they have in tests managed to cool the flagship Core i9-12900K at 160 watts power outlet. It is above the base frequency to be reached at 125 watts, but well below the maximum 241 watts that Intel specifies. However, it is worth noting that Noctua on its website clearly specifies that the NH-L9i is not adapted for systems that generate a lot of heat.

In addition to a new revision of the radiator, Noctua also presents a kind of fan tunnel called NA-FD1. It is intended to be placed as a bridge between the radiator and a perforated side panel or top. By creating a tunnel between the fan and an air intake, the radiator is prevented from taking in the already heated air in the chassis. The insert is intended to be used when the space is larger than 5 millimeters, but a maximum of 45 millimeters.


According to Noctua, depending on the remaining system, NA-FD1 can lower temperatures by as much as 5 ° C or more. The tunnel itself consists of several inserts in EVA foam in different thicknesses that can be combined to reach the desired height. The accessory is purchased separately and is compatible with all versions of NH-L9i and NH-L9a. The price tag lands at a total of 12.90 euros, corresponding to just under 130 kronor.

The cooler is available both in Nocuta’s classic brown-beige design and in the Chromax Black version. The price lands at 44.90 euros for the brown-beige or 54.90 euros for the black, corresponding to approximately SEK 445 and SEK 545 respectively.
