The NH-L9i is a premium quality quiet CPU cooler for Intel LGA115x based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9i is ideal for extremely slim cases and due to its 95x95mm footprint, it provides full compatibility with tall RAM modules and VGA cards on mini-ITX mainboards. The custom designed SecuFirm2 mounting system for LGA115x makes installation child's play and thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9i runs remarkably quiet. Topped off with Noctua's renowned NT-H1 thermal compound, the NH-L9i fuses everything users have come to expect from Noctua's larger coolers into a super-compact package for slim HTPC systems.

Noctua quality speaks volumes. Delivery was very fast. Good seller !


September 2020

Got this for a mini itx non gaming build. Used the InWin Chopin case and this cpu cooler fits perfectly. Great quality from Noctua as their reputation suggests


May 2020

Arived promptly, well packaged, all mounting screws & heat sink paste supplied. Fits perfectly on to a ROG STRIX Z270-I mini ITX board with its low profile & is extremely quiet.


March 2020

Not as quiet as it claims, but is pretty slim after all. Using it to cool an AMD Ryzen 5 3600 (the NH-L9i and NHL9a both require a kit to work with AM4 sockets, the AM4 model wasn't available when I bought this). Easy to fit with the kit and fits well. Note that it needs a back plate fitted, so if your case doesn't have a slot cut out you'll need access to the rear of the mainboard to fit it. Despite its quiet claims and rating being good enough for the chip, it is almost constantly audible. I work from home a lot and need a quiet PC for work. Even just with little more than the browser open I can constantly hear the fan running, and spinning up and down every couple of minutes. Before setting the profile to quiet in the BIOS it was even worse. It does a decent job of keeping the CPU cool-ish though, so if you have a slim case and don't need it completely silent then this cooler is OK. But, if you need silence and you have the space in your case, get something bigger and quieter for the same price.
