Noctua has a long history of making some of the finest cooling gear available to enthusiasts. They make top-notch gear which is well built and performs exceptionally.

The L9i is no exception to this. It comes packed in a thick cardboard box. After opening the box, you’ll find the mounting screws, their special Low noise Adapter and a syringe of Noctua NT-H1 thermal paste with the cooler held in its place with a dense foam. A case badge is also supplied.

Just to note, the syringe comes with a generous amount of thermal paste where you can apply it more than once, unlike some who either provide for a single application- or none at all. Not that I am saying its bad, but it’s good to see Noctua has you covered in that regard.

The CPU cooler is very well built. It comes with 6 years of warranty and by the looks of it. As per their guidelines, it’s rated for 65w TDP processors and is specifically designed for HTPC/Low clearance setups.

The L9i is specifically for Intel LGA1150, LGA1155 and LGA1156 sockets. For those looking out for AMD sockets, there’s the L9a.

Noctua’s sink comes with a Noctua NF-A9x14 PWM fan pre-installed that uses SS02 bearing, with an advertised max rotational speed of 2500RPM and with low noise adapter, its advertised to run 1800 RPM, with the minimum speed of 300 RPM. Noctua has mentioned that the dimensions of the cooler are 37x 95x 95mm with a weight of 420g. It uses nickel-plated copper for its base and heat pipes.

  1. apache’s mounting is shit. most people will push the thermal towards the side of the level during the mount. apache makes a lot more sense…xigmatek makes a lot of coolers with direct heatpipes so that’s cool…..

    what kind of bearing do the xigmatek fans use?

  2. sorry..praeton makes a lot more sense…..

  3. i wouldn’t be suprised if its sleeve bearing. But couldn’t be sure since apache’s mounting is fixed and as far as praeton goes, the rear is completely sealed.

  4. Thank you for writing this article! I’ve been looking for a low-pro heatsink to fit inside of an ultra-mini gaming PC and this is just what I needed to help make my decision. Noctua it is! Thanks again:)

  5. Thanks for reading! 🙂 I am sure you will not be dissapointed. Just make sure the processor you’re pairing this cooler with is under the recommended TDP pocket.

  6. Glad to be of some help 🙂
    On a side note, congrats on getting a new rig. Happy Gaming
