Award-winning NH-L9x65 cooler

Award-winning NH-L9x65 cooler

Tens of thousands of enthusiast users all over the world swear by the NH-L9x65’s quality and performance. Recommended by more than 100 international hardware websites and magazines, it is renowned for being one of the best sub-70mm low-profile heatsinks on the market.
Dedicated special edition for AM4

Dedicated special edition for AM4

The NH-L9x65 SE-AM4 brings the NH-L9x65’s signature quiet cooling performance to AMD’s new AM4 platform. With its highly compact design and low profile, it is ideal for cooling lower TDP AM4 CPUs in HTPC or Small Form Factor cases.
65mm low profile

65mm low profile

Due to its compact heatsink and the 14mm thin NF-A9x14 low profile fan, the NH-L9x65 stands only 65mm tall (the same height as low-profile expansion cards), which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer limited clearance for CPU coolers.
100% RAM compatibility

100% RAM compatibility

Being 95mm wide, the NH-L9x65 SE-AM4 complies with the AMD AM4 socket’s keep-out zone. This means that it won’t cause issues with chipset coolers and doesn’t overhang the RAM slots, making it fully compatible with tall memory modules.
100% compatibility with PCIe cards on mini-ITX

100% compatibility with PCIe cards on mini-ITX

Many mini-ITX mainboards have the PCIe slot sitting close to the socket zone. While larger coolers with 120mm or 140mm fans that exceed this zone may block the PCIe slot, the compact NH-L9x65 provides full compatibility with PCIe cards.
Easy access to near-socket connectors

Easy access to near-socket connectors

Many low-profile coolers use larger fans or heatsinks in order to achieve sufficient cooling performance, but by protruding over the socket zone, they make it difficult or even impossible to reach near-socket connectors on tightly packed ITX mainboards. Thanks to its compact footprint, the NH-L9x65 provides easy access to all connectors and components.
NF-A9x14 PWM premium fan

NH-L9x65 SE-AM4 Review

Si vous cherchez un ventirad qui aura le maximum de performances alors le NH-D15 est fait pour vous, si vous avez la place de le caser sur la carte mère et dans le boitier. Le NH-U12S quant à lui permet d'être installé dans beaucoup plus de configurations différentes avec une taille largement plus petite que son grand frère, les performances sont bien entendu moins bonnes mais largement suffisantes pour tenir un processeur au frais. Le NH-L9x65 pour finir est définitivement adapté pour les boitiers qui ne dispose que de très peu d'espace, il sera suffisant pour un processeur aux fréquences d'origine mais si vous comptez overclocker il faudra s'orienter vers un modèle plus imposant.
Test verdict: "Au final on a toujours une qualité de fabrication et une finition sans défauts et les ventilateurs sont excellents." (Christian Marchini, Conseil Config)

NH-L9x65 SE-AM4 Review

Este disipador es algo más sencillo que los otros que hemos analizado y pese a que podría ser una buena opción para los Ryzen 7, lo vemos más bien destinado a los Ryzen 5, por eso lo hemos probado con el Ryzen 5 1600 que analizamos unas semanas atrás. Podemos ver que es ideal, porque sin carga se mueve en los 34ºC, llegando a los 58ºC de media, mientras que durante los benchmkar sintácticos este disipador se ha movido entre los 70ºC y los 75ºC. Hay que tener en cuenta que los benchmark sintéticos son utilidades que estarán al máximo al procesador, pero en la vida real no llegaremos a tales niveles, moviéndonos siempre en cargas menores, por lo tanto la temperatura sera bastante más comedida.
Test verdict: "El Noctua NH-L9x65 SE-AM4 ha sido desarrollado, sin ninguna duda, para configuraciones de bajo perfil basadas en procesadores AMD Ryzen. Sin duda estamos ante una excelente solución de Noctua, desarrollado para ofrecer una gran disipación del calor en equipos mini-ITX o micro-ATX, donde el hardware suele estar bastante concentrado. El problema de los equipos compactos es la temperatura, que al estar todo más junto, se suele reducir el flujo de aire o este ve dificultado su recorrido, pero en este caso la solución de Noctua nos ayudara con este problema, ya que es potente y altamente eficiente."

NH-L9x65 SE-AM4 Review

Come è lecito aspettarsi, salendo di fascia di prezzo (e dimensioni, e numero di ventole) le temperature vedono un calo significativo: nonostante questo, però, le dimensioni dell’NH-L9x65 non ne pregiudicano l’ottimo livello di performance, con una ΔT di appena 46 °C con la temperatura ambiente; tenete a mente che si tratta di un dissipatore alto 65mm e paragonabile, in dimensioni, ad un tradizionale heatsink stock di AMD e Intel, caratterizzato però da un’elevatissima silenziosità, grazie alla ventola NF-A9x14 ad altezza ridotta.
Test verdict: "Il Noctua NH-L9x65 SE-AM4 è un heatsink compatto, dalle buone prestazioni e molto più silenzioso del classico dissipatore stock, di cui cerca di essere un sostituto migliore in tutto." (Ciro Sdino, ReHWolution.it)

NH-L9x65 SE-AM4 Review

My testing did show that this little cooler that can almost fit in the palm of your hand still kept an overclocked Ryzen 1700 a few degrees below 80 C. While that is a bit on the high side, I hesitate to list the cooling performance as a Con, because if you use the cooler within the design intention, which is small form factor cases and HTPC environments, then you will have no problems. It does a fine job of cooling. If you try to cool an overclocked gaming system, well, Noctua has a variety of coolers that are better choices.As for the acoustics, the Noctua NF-A9x14 fan is quite even at full speed. The case fans drowned out any sound from the Noctua fan.
Test verdict: "While large coolers are impressive and fun to show off, for small form factor builds you need a cooler that can get the job done in a small space. And that is just what the NH-L9x65 SE-AM4 does. The engineering that went into the entire package for the NH-L9x65 SE-AM4 is remarkable, from literally the box and internal packaging, to the installation hardware, cooler, and fan." (Ambrosidou Nat, XtremeSystems.org)

Should I take the cooler off before transporting my system?

Due to the low weight of the cooler, it is not necessary to take it off for transport.

How should I clean my Noctua cooler?

Dust: Fans and heatsinks inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fan and heatsink regularly. For cleaning, please first remove the fan from the heatsink and clean it using a duster, slightly moist tissue or canned air. Please be careful not to use too much force in order to prevent any damage to the fan. Please do not use a vacuum cleaner as this may apply excessive force to the fan and do not put the fan under running water as water residues inside the motor may lead to short circuits. Please also note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty. Before reinstalling the fan, clean the heatsink itself with a duster or vacuum cleaner. Do not use water to clean the cooler. Finally put the fan back on and connect it to your motherboard fan header or fan controller.
Thermal paste residues: Whenever you take off the heatsink from the CPU, we recommend to clean the CPU as well as the base of the cooler before re-applying thermal paste and re-installing the cooler. You can either just wipe the base and the CPU clean with a dry, lint-free tissue or, for more thorough cleaning, use a lint-free tissue moistened with either a mild solution of washing-up liquid or isopropyl alcohol. Do not put the cooler or CPU under running water. Note that both the base of the heatsink and the CPU should be dry, free from residues of thermal compound and free from grease before re-applying thermal paste and re-installing the cooler.

What Thermal Design Power (TDP) is this cooler recommended for and how much Watt (W) of heat can it dissipate?

Please refer to our TDP guide for information on maximum recommended TDP and heat dissipation.

My case supports CPU coolers of up to XXXmm height, which model should I choose?

Please refer to our TDP guide in order to select the cooler that offers the best cooling performance at a given height.

I have difficulties installing the cooler, can you help?

Please refer to the installation manual and our video installation guides for detailed instructions on how to install the cooler.

Can I keep using the backplate / mounting system of my previous Noctua cooler for my new one?

Most Noctua SecuFirm™ mounting parts are cross-compatible, so if you’re replacing one Noctua cooler with another, it is usually possible to keep the original backplate and/or mounting system in place in order to re-use it for the new cooler. If you had your previous Noctua cooler installed on an Intel LGA115x (LGA1156, LGA1155, LGA1151, LGA1150), LGA2011 (LGA2011-0, LGA2011-3) or LGA1366 system and replace it with an NH-U14S, NH-U12S or NH-U9S, you only need to replace the original mounting bars with the NM-IMB3 ones supplied with the new cooler. For all other models, you can keep the entire mounting system in place on the aforementioned Intel sockets. On AMD AM2, AM2+, AM3, AM3+, FM1, FM2, FM2+, you only need to replace the original mounting bars with the ones supplied with the new cooler.

How much torque should be applied when tightening the screws of a Noctua CPU cooler?

All screws should be tightened gently until they stop without using excessive force. Please do not exceed the following values for maximum tightening torque:
Screw typeMax. torque
NM-SSC1 screws for fixing the fastening brackets to the base of the heatsink0.5 Nm
NM-ITS1 thumb screws for fixing Intel mounting bars0.5 Nm
NM-ALS1 screws for fixing AMD mounting bars0.6 Nm
Spring-loaded screws for fixing the heatsink to the mounting bars0.6 Nm

Which Noctua fan or CPU cooler should I buy? How to choose the right model?

Not sure which Noctua product to buy? Our detailed buying guides for fans and CPU coolers help you to choose the model that works best for you.

How can I determine if the motherboard’s UEFI BIOS is overclocking my processor by default and deactivate this automatic overclocking?

Most motherboard vendors allow their overclocking-enabled products (e.g. those with Intels X- or Z-series chipsets) to run the processor at increased clock speeds by default, without requiring any user action at all. Since TDP (Thermal Design Power) limits are usually also disabled by default, this leads to the CPU exceeding the rated TDP to a varying degree, depending on the used applications and their workloads. Due to the increased heat output of the CPU, you may see higher CPU temperatures than expected.

In order to find out if your motherboard is overclocking your processor by default, please enter the UEFI BIOS and select the “advanced” or “overclocking” menu. There you should be able to find options such as “MultiCore Enhancement” (options: enabled/disabled), “CPU Ratio Apply Mode” (options: all/per core) or similar. To disable the automatic overclocking, adjust the settings either to “disabled” or “per core” and make sure that the individual multipliers match the original specifications.

In doubt, please contact your motherboard vendor for detailed instructions on how to disable this feature.

Which Noctua CPU coolers are compatible with Intel LGA2066?

Due to the heatsink mounting mechanism being identical on LGA2011 and LGA2066, Noctua’s SecuFirm2™ mounting systems for LGA2011 also support Intel’s upcoming ‘Basin Falls’ X299 HEDT (High End Desktop) platform for ‘Skylake-X’ and ‘Kaby Lake-X’ processors. Most current Noctua coolers already include SecuFirm2™ mounting systems for LGA2011 and can thus be used on LGA2066 motherboards without any upgrades or modifications.

The following models include a mounting-kit for socket LGA2011/2066 and are thus compatible out of the box:

Can I install a Noctua cooler in my system from Acer, Dell, HP or Lenovo?

Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often use motherboards which differ slightly from the specifications issued by Intel and AMD. While those changes are usually subtle, they can lead to compatibility issues with coolers that where built to comply with these specifications.

Even in case the cooler is mechanically compatible and can be installed, other issues can occur, e.g. proprietary fan connectors, BIOS errors due to a low fan speed, shutdowns, etc. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues can often not be resolved.

Due to the large number of possible issues that cannot be resolved with different mounting parts alone, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?
