Product discontinued. Successor model: NH-L9a-AM4

The NH-L9a is a premium quality quiet CPU cooler for AMD based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9a is ideal for extremely slim cases and due to its 92x114mm footprint, it provides excellent compatibility with tall RAM modules and other components on mini-ITX mainboards. The custom designed SecuFirm2™ mounting system for AM3+/FM1/FM2/FM2+ makes installation a child’s play and thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9a runs remarkably quiet. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9a fuses everything users have come to expect from Noctua’s larger coolers into a super-compact package for slim HTPC systems.

  Caution:  The NH-L9a is a highly-compact low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and only recommended for CPUs with up to 65W TDP (Thermal Design Power). Please consult our TDP guidelines to find out whether the NH-L9a is recommended for your CPU.

NH-L9a Review

Having a compact cooler is nice and all, but cooling performance is what really matters. To test this out I employed the might of an 8-core, 16-thread Ryzen 7 1700 CPU. The processor was tested at stock, 3.55GHz, and 3.75GHz. The Furmark CPU burn in utility was used to push all cores to 100% load. Overall I was very impressed by the coolers performance. It handled the 65W Ryzen 7 1700 without much issue at all. I was even able to do a substantial overclock without even coming close to the thermal limit. This is a testament to both the efficiency of Ryzen 7 chips, and the quality of the cooler.
Test verdict: "If you have an NH-L9i or L9a, I would pickup the free upgrade kit ASAP." (Jay, Tek Everything)

NH-L9a Review

Como conclusión, después de realizar las pruebas de rendimiento, podemos decir que este disipador cumple con su cometido en procesadores de gama media o baja y sin OC, además de tener un perfil bastante bajo, mejorando aún más la colocación en torres de reducidas dimensiones. En cuanto a los accesorios que trae, como estamos habituados, Noctua incorpora un completo juego para mejorar la conectividad del disipador con la placa base, además de traer la pasta térmica y un reductor de ruido, entre otros. Sin embargo, en este caso, echamos en falta la llave de estrella que suele incluir en otros disipadores para poder apretar los tornillos. En cuanto a ruido producido por el ventilador, aún funcionando al 100% de su capacidad no llegamos a notar que sea molesto, este es un aspecto que Noctua cuida mucho en todos los ventiladores que fabrica.
Test verdict: "Por todo ello, vemos que después de las pruebas realizadas, este disipador cumple muy bien el cometido para que fue pensado, teniendo una buena relación calidad-precio, recomendando su uso en un entorno de dimensiones reducidas donde necesitamos una buena refrigeración."

NH-L9a Review

Der Kühlkörper wurde seitens Noctua erwartungsgemäß gut verarbeitet und bietet in diesem Punkt keinen Anlass zu negativer Kritik. Damit stellt der Hersteller abermals unter Beweis, dass unabhängig von der Größe des CPU-Kühlers die Verarbeitungsqualität im Hause Noctua hoch gehalten wird.
Test verdict: "Noctua bietet mit dem NH-L9a einen kleinen, schmucken Low-Profile CPU-Kühler in höchster Verarbeitungsqualität, welcher auch im aller kleinsten System Platz findet. Die Fertigungsgüte ist bis ins kleinste Detail äußerst präzise umgesetzt und kann einen bleibenden Eindruck hinterlassen." (Tobias Mann, PCMasters.de)

NH-L9a Review

Uno de los aspectos a tener en cuenta es que Noctua especifica en su pagina web que el Noctua NH-L9i y el NH-L9a están diseñados para CPUs de hasta 65W de potencia térmica, aunque en caso de utilizar uno de mayor potencia tampoco pasa nada, aunque no tiene mucha lógica debido a que para este fin tenemos disipadores mejores e incluso más baratos. Para realizar la prueba se ha empleado un procesador 3770K que no es ni remotamente el idóneo pero ha aguantado de forma correcta los 77W. Aunque una vez lo probamos es imposible perder lo de vista, ya que la gran virtud de este disipador es que con 37 mm existen pocos disipadores con un perfil menor que este en el mercado y aun menos con la capacidad de que se encuentren diseñados para un consumo moderado y potencias térmicas limitadas. Las pruebas realizadas en idle y en full dejan un buen resultado, ademas hay que destacar su sonoridad, ya que apenas se escucha el disipador.
Test verdict: "Sin duda alguna los disipadores Noctua NH-L9i y NH-L9a son una opción recomendable para todos aquellos usuarios que quieran disponer de equipos pequeños a un sonido bajo, el punto negativo a estos disipadores es el precio ya que se encuentran con un precio aproximado de 50€ cada uno, pero aun así no deja de ser un precio adecuado para unos disipadores de una gran calidad."

NH-L9a Review

Después de probar los modelos Noctua NH-L9i y Noctua NH-L9a hemos podido comprobar otra vez como esta marca sigue en su línea de calidad, los acabados y materiales son excelentes. El rendimiento térmico está en la línea de lo exigido a un producto así que como es lógico no está diseñado para realizar OC del procesador. En cuanto al nivel de sonoridad como hemos podido comprobar casi son imperceptibles en un uso normal y molestan muy poco cuando se les exige algo más.
Test verdict: "Un modelo que se merece nuestro sello de producto recomendado ya que seguro que no defrauda a quien busque este tamaño de disipador para su caja." (Joaquin Prida Trujillo, AndroidPC.es)

NH-L9a Review

[E]specially when taking the rated 65w limit into account, the cooler performs admirably in the face of the higher thermal load provided by our test bench. And, during our load tests, the L9a manages to significantly outperform AMD’s own stock low profile cooler, which is taller than the L9a. The recently tested Scythe Kodati is also easily bested, although this isn’t too surprising given that the Kodati has a smaller fan. During testing, the sound output of the L9a felt very similar to the other cooler we tested, the Noctua NH-L9x65 (review coming soon!). This is not at all suprising, as they use the exact same uprated NF-A9x14 fan. Consequently, the fan was never ‘loud’, and the sound signature was always pleasing and non-obtrusive. That’s quite the achievement, given the fact that our load testing exceeded the TDP of the cooler by a whopping 23%!
Test verdict: "The Noctua NH-L9a is an excellent performer, considering it’s size. Being this small, it was always going to be a challenge for it to keep our hot 89W test CPU under control, but the NH-L9a did manage to achieve this – your chassis ambient temperature would have to top 45 degrees celcius for the cooler to hit the AMD thermal limit of 65C."

Jest to dość cicha jednostka i w pełni kompatybilna z pierwszym slotem PCI-E czy pamięciami ram. Posiadacze platformy Intel powinni wybrać wersję oznaczoną "i". Model "a" przeznaczony jest na procesory firmy AMD. W środku znajdziemy wszystkie niezbędne narzędzia do zainstalowania chłodzenia na płycie głównej. Podobnie jak w przypadku wielu produktów od firmy Noctua, instalacja jest dziecinie prosta.

NH-L9a Review

So what advantage does this cooler have over the bundled stock heatsink? For one, the unit is virtually inaudible and extremely quiet. By default, the included fan operates at 2500 rpm and contains an Acoustical Noise level of 23.6 db(A). When you attach the Low Noise Adapter, this limits the fan speed to 1800 rpm and dramatically reduced the noise rating to 14.8 db(A).
Test verdict: "The Noctua NH-L9i is undoubtedly the coolest and quietest ITX heatsink I’ve tested. Noctua have performed miracles when you consider the high-airflow and reasonable temperatures given its limiting size." (John Williamson, TruePCGaming.com)

La qualité de fabrication est comme d'habitude chez Noctua irréprochable, le bundle fournit tout ce qu'il faut pour monter le ventirad sans problèmes et le montage se fait très rapidement (4 vis et hop c'est monté). Au niveau des performances ils sont capables de refroidir un processeur de 95 Watts, il faudra cependant privilégier un processeur de type Core i3 ou Pentium G pour garder un silence appréciable.

NH-L9a Review

Noctua‘nın kasa boyutlarından ötürü soğutma açısından sıkıntı yaşayan kullanıcılar için geliştirdiği NH-L9 serisine ait Intel işlemcilere özel NH-L9i modelinden sonra AMD işlemcilere özel NH-L9a modelini de inceledik. İkisi de 14 mm kalınlıklı ince tip Noctua NF-A9x14 fanla geliyor. AMD özel modelde radyatör tasarımı kare yerine dikdörtgen ve böylece standart AMD işlemci soketindeki deliklere uyacak yapı benimseniyor ama bundan ötürü soğutucu sadece bir doğrultuda sabitlenebiliyor. ASRock Soket FM2+ anakartımızla yaptığımız testte herhangi bir sorun yaşamadık. Sadece arka plakasız montaj gerekti ama işlem son derece basit ve fazla zaman almıyor. Bununla birlikte montaj sonrasında soğutucu stabil ve oynama yok. Büyük boyutlu bir tüp kaliteli termal macunla gelen işlemci soğutucusunda malzeme, işçilik ve kutulama seviyesi birinci sınıf. Alüminyum plakalar, bakır ısı boruları ve tabana nikel kaplama uygulandığı için daha hoş görünüyor, kullanım ömrü uzuyor ve korozyon riski düşüyor. Benzer soğutucular aksine 80 değil 92 mm fan kullanıldığı için daha düşük devir ve gürültüyle daha iyi soğutma elde edilebiliyor. Gerçekten de tamamen sessiz olsun isterseniz kutudaki LNA filtreyi ekleyebilirsiniz ama PWM destekli olduğundan filtresizken bile 1500 devirde kalıyor ve varlığını belli etmiyor.
Test verdict: "AMD işlemcili Mini ITX anakart ve kasa sahiplerinin yüzünü güldürecek" (Gorkem Yildirim, PCkoloji.com)

Installation Manual (PDF)

Information Sheet (PDF)

Can the cooler be used on mainboards where components on the rear side prevent the installation of the backplate?

Yes, the cooler can be installed on such mainboards using the NM-APS3 plastic spacers as shown below. The NM-APS3 spacers have been included within the NH-L9a’s scope of delivery since April 2013. If your NH-L9a didn’t yet include the NM-APS3 spacers and if you would like to install the cooler on a mainboard where components on the rear side prevent the installation of the backplate, please contact our customer support. We will send you the NM-APS3 spacers free of charge if you provide a proof of purchase (scan, photo or electronic copy of the invoice) of both the cooler and the mainboard.



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.

My unlocked Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?

Intel's unlocked CPUs (K, X and C suffix) can dissipate more heat than indicated by the TDP specification if
  1. the TDP limits are extended or disabled in the motherboards' BIOS.
  2. the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
  3. some software creates untypical loads, e.g. Prime95 with AVX2 support and a) and/or b) apply.

This can lead to temperature issues, especially when using smaller coolers or compact cases.

The actual power draw of the processor can be monitored with software provided by the motherboard vendor or with 3rd party tools like HWInfo or HWMonitor.

If you encounter temperature issues (>90°C) and notice a higher than specified power draw, please ensure that no automatic overclocking is applied and limit the TDP to the specified value by choosing appropriate BIOS settings.

For Kaby Lake CPUs, it may also help to lower the CPU clock speed for applications that heavily use the AVX instruction set, which can lead to higher loads and power draw. This option is usually referred to as “AVX offset” and makes it possible to lower the multiplier specifically for AVX based applications without reducing performance when using other instruction sets. Depending on the quality of the CPU and the programs being used, a reduction of 2-3 steps usually gives very good results.

Please contact your motherboard vendor for details if you have trouble finding the appropriate settings in the BIOS.

All our TDP recommendations are based on thorough testing with the default values specified by Intel using popular applications such as Asus Realbench and prime95. Please note, however, that prime95 creates a particularly high load that goes beyond typical application scenarios and this leads to elevated temperatures. We thus recommend using other programs such as Realbench for checking the stability and temperatures of the CPU in realistic scenarios.

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.

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 mounting brackets don’t touch the mainboard, is this an issue?

No. The mounting brackets are not meant to touch the mainboard and the flexibility of the brackets is required to create the appropriate contact pressure. There should be up to 3mm (Intel) or 4mm (AMD) space between the mainboard and the mounting brackets when the cooler is correctly installed.

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.

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

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.

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 were 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.

Can I upgrade my existing Noctua cooler to socket TR4 or SP3?

Unfortunately, it is not possible to upgrade existing Noctua heatsinks to support the AMD TR4 and SP3 sockets for Ryzen Threadripper (X399) and Epyc CPUs. TR4/SP3 CPUs have much bigger heatspreaders (as compared to e.g. LGA2066 or AM4 processors) and the contact surfaces of standard Noctua heatsinks would cover only about half of these heatspreaders, which would result in insufficient cooling performance. On top of that, the heatpipes of bigger cooler models like the NH-D15 or NH-D15S would completely block the RAM slots on many TR4/SP3 motherboards. For this reason, Noctua has introduced the new NH-U14S TR4-SP3, NH-U12S TR4-SP3 and NH-U9 TR4-SP3 cooler models that feature bigger contact surfaces and have been tailored to fit TR4 and SP3 systems. Please choose these models for AMD Ryzen Threadripper and Epyc systems.
