The NH-D9L is a premium grade dual tower CPU cooler that has been designed to provide excellent quiet cooling performance at a height of only 110mm. Its comparably low profile (15mm lower than classic 9cm tower coolers such as the NH-U9S) doesn’t only guarantee full 3U compliance but also makes the NH-D9L ideal for compact HTPC and Small Form Factor cases that have airflow paths parallel to the mainboard. Thanks to its 95x95mm footprint, the NH-D9L clears the RAM and PCIe slots on all Intel based and most AMD based ITX mainboards. The included NF-A9 premium fan supports automatic speed control via PWM for outstanding quietness of operation and a second, optional NF-A9 fan can be added for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2™ multi-socket mounting system, Noctua’s proven NT-H1 thermal compound and full 6 years manufacturer’s warranty, the NH-D9L forms a highly compact premium package for space-restricted applications.

Low-profile tower design for better airflow efficiency

Low-profile tower design for better airflow efficiency

While most low-profile coolers blow air towards the motherboard, the NH-D9L is a tower style cooler that bows parallel to the mainboard, which allows for superior airflow efficiency in cases with front intake and rear exhaust fans that create an airflow path parallel to the mainboard.
3U compatibility

3U compatibility

Whereas classic 9cm coolers with up to 125mm height fit 4U rack mount cases, the NH-D9L's reduced height of 110mm allows it to also fit 3U chassis. This makes it ideal for noise-sensitive 3U applications in fields such as audio or video processing.
100% RAM compatibility

100% RAM compatibility

With its 95x95mm footprint, the NH-D9L does not overhang the RAM slots on current Intel and most AMD mainboards. This gives the user full access to the memory modules and guarantees 100% compatibility with tall heatspreaders or optional memory fans.*
100% compatibility with PCIe cards on mini-ITX

100% compatibility with PCIe cards on mini-ITX

Many Intel LGA115x based mini-ITX mainboards have the PCIe slot sitting right next to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-D9L provides full compatibility with PCIe cards, be it on ATX, microATX or ITX.
NF-A9 premium fan

NF-A9 premium fan

The highly optimised features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, which allows it to further improve the renowned efficiency of Noctua's previous 92mm models and contributes to the NH-D9L' superior cooling performance.
PWM support and Low-Noise Adaptor

PWM support and Low-Noise Adaptor

The NF-A9 92mm fan supplied with the NH-D9L supports PWM for convenient automatic speed control through the mainboard. In addition, the maximum fan speed can be reduced from 2000 to 1550rpm using the supplied Low-Noise Adaptor for even quieter operation.
Dual fan ready

Dual fan ready

The NH-D9L includes an extra set of fan mounting clips for users who want to achieve even better cooling performance by adding a second, optional NF-A9 to the front fin stack. Using the y-cable supplied with the NF-A9 PWM retail fan, both fans can be connected to one CPU fan header.**
SecuFirm2™ mounting system

SecuFirm2™ mounting system

Noctua's SecuFirm2™ mounting systems have become synonymous with quality, safety and ease of use. Supporting Intel LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), LGA2011 (LGA2011-0 & LGA2011-3) and AMD (AM2+, AM3, AM3+, FM1, FM2, FM2+), the SecuFirm2™ mounting included with the NH-D9L guarantees perfect contact pressure and maximum convenience on all current sockets.
Compatibility with past and future sockets

Compatibility with past and future sockets

Complying with the open SecuFirm™ standard, the NH-D9L can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets.
6-year manufacturer’s warranty

6-year manufacturer’s warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9 features an MTBF rating of more than 150.000 hours and the entire NH-D9L package comes with a full 6-year manufacturer’s warranty.
*Some AMD mainboards violate the 96x114mm keep-out zone specified by AMD, so the NH-D9L can only be used with RAM modules of up to 30mm height on these boards. Please consult our compatibility list for details. **The optional front fan will sit above the RAM and depending on the height of the RAM modules, the fan may have to be moved up so far that the total height of the cooler exceeds 110mm. As a result, the cooler may no longer fit some 3U cases. In order to guarantee full 3U compatibility in dual fan mode, please use low profile memory with up to 22mm height.

NH-D9L Review

Noctua nous livre une fois de plus du bon Noctua. Le NH-D9L est soigné dans sa conception et offre une finition haut de gamme à l'autrichienne. Pour appuyer le côté premium du ventirad, il est accompagné d'un bundle très complet comme nous l'offre généralement la marque au hibou. Performant, compact et polyvalent, le petit double tour saura prendre soin de votre processeur, qu'il soit utilisé dans un serveur (compatibilité U3), dans une petite station de travail ou dans un home cinéma; sa hauteur ne sera pas contraignante. Nous apprécions toujours autant la facilité d'installation des produits Noctua, la fixation étant très simple à manipuler. Les performances sont excellentes pour ce petit modèle dont les capacités de dissipation max seront limitées à 140W. Au-delà de ce seuil, il sera nécessaire de l'équiper d'un second ventilateur et de l'installer dans un boîtier bien aéré.
Test verdict: "À l'issue de notre dossier et à la vue de tous les éléments évoqués, nous n'hésiterons pas une seule seconde à gratifier le Noctua NH-D9L de nos 5 étoiles." (Thierry Comtesse, Le Comptoir du Hardware)

NH-D9L Review

Il sistema di montaggio sviluppato da Noctua, SecuFirm2™ risulta parecchio semplice e intuitivo, grazie anche al cacciavite già fornito in dotazione. Nonostante la ventola abbia un diametro di soli 90 mm in idle risulta praticamente inudibile rispetto alle altre ventole presenti nel case . Ciò denota una elevata qualità costruttiva, la velocità minima di rotazione ammonta a 400 RPM mentre sotto carico arriva fino a 2000 RPM, la rumorosità massima dichiarata è di soli 22,8 dB(senza Adattatore Low noise), la rumorosità massima dichiarata con l’adattatore Low noise è di 16,3 dB(A), praticamente inudibile a scapito delle prestazioni ridotte. Ovviamente sotto sforzo è udibile un ronzio((senza Adattatore Low noise) ma nulla a che vedere rispetto ai modelli stock di dissipatori, le ventole supplementari del case usato per i test sono risultate indubbiamente più rumorose. Sul piano delle performance il Noctua NH-D9L si difende bene, nonostante le dimensioni ridotte e un processore non proprio “tranquillo” in fatto di temperature. Per effettuare i nostri test abbiamo affidato al NH-D9L un processore AMD FX 8350 a frequenze stock(4.0 GHz). In idle abbiamo rilevato una temperatura più che accettabile di 35 °C. Durante le sessioni di gaming più impegnative con Battlefield 1 invece la temperatura si è attestata sui 55 °C. Un ottimo risultato per il piccolo di casa Noctua. Date le ridotte dimensioni di corpo lamellare e ventola, l’overclock con questo dissipatore è sconsigliato. Noctua confida nella qualità costruttiva con cui realizza i suoi prodotti, l’ NH-D9L è garantito ben 6 anni.
Test verdict: "Nonostante la maggior parte dei dissipatori bitorre risulti parecchio ingombrante, il Noctua NH-D9L è uno dei bitorre più piccoli sul mercato, caratteristica che permette l'installazione insieme a moduli RAM ad alto profilo e sistemi di ridotte dimensioni HTPC. Come i modelli di Noctua ci hanno abituato anche questo dissipatore fa della silenziosità e qualità costruttiva i suoi punti di forza. Saldature eccellenti, design ben studiato, rumorosità ridotta al minimo nonché una dotazione molto completa." (Daniele Massari, GamesVillage.it)

NH-D9L Review

لكل فعل رد فعل مساوى له فى المقدار ومضاد له فى الأتجاه. نعلم جميعاً قانون نيوتن الثالث وبالفعل, نرى ذلك فى الأجواء التقنية الأن. فإن الفعل الخاص بتصغير دقة التصنيع لأشباه الموصلات يصاحبها ردة الفعل فى الحاجة الى تطوير أنظمة التبريد لتقوم بمعادلة الأنبعاث الحرارى لها. جميعنا نُعجب بصناديق الحاسب ذات أنظمة التبريد المائية المُعدلة ولكن لا زال التبريد الهوائى يفرض نفسه حتى الأن بين أنظمة التبريد المختلفة, ومن هنا جائت شركة Noctua لتنفرد بمنتجاتها المتميزة فى حلول التبريد الهوائية لمختلف الأستخدامات والمجالات. نحن لدينا اليوم أحد تلك المنتجات وهوا المُبرد الهوائى Noctua NH-D9L صاحب بُرجى التبريد صغير الحجم ليتناسب مع صناديق الحاسب SFF وكذلك صناديق حواسب الخوادم.
Test verdict: "ستحصل فى المقابل من أداء يستحق السعر. المٌبرد Noctua NH-D9L قد حقق تلك المعادلة الصعبة فى الأداء المتميز للأختيارات المتعددة لمجموعة كبيرة من المستخدمين مع الأحتفاظ بالسعر المقبول الذى لا يتعدى 55$ فأنه يستحق ذلك السعر بالتأكيد." (Mustafa Elmarghani, ArabHardware.net)

NH-D9L Review

Después de realizar diferentes pruebas, ya sea con uno o dos ventiladores, y de trabajo, tanto en un uso normal como al 100% de funcionamiento del procesador, podemos sacar la siguiente conclusion: éste es un ventilador para procesadores de media o baja potencia, ya que con los más potentes se sobrecalienta en exceso, con lo que estaremos mermando la vida del mismo. También vimos como implementando un ventilador extra, con un funcionamiento en paralelo con el primero, conseguimos bajar la temperatura del procesador en unos 5º con respecto al uso de un solo ventilador, mejorando por tanto el flujo de aire que pasa a través del mismo.
Test verdict: "Con esto, podemos ver que el Noctua NH-D9L se trata de un disipador perfecto para aquellas cajas donde no haya mucho espacio o para aquellos procesadores de gama media donde va perfecto, manteniendo la temperatura estable con un nivel de sonoro moderado."

NH-D9L Review

So the time has come, I’ve put both the NH-U9S and NH-D9L through their paces and while there is a clear winner in performance, they are both very worthy coolers. By today’s standards, these coolers are a bit smaller than most we see as companies lately have taken go big or go home to a whole new level. Noctua has graced us with some more normal sized coolers that still offer great performance.
Test verdict: Both the U9S and D9L were able to handle the heat and stayed within the limits of safety for CPU temps, which is very important, especially when overclocking. As per their standard configurations, both of these coolers only come with one fan, but adding the second fan does allow for a bit better temperatures, even if not by much. Adding the second fan onto the coolers and temperatures dropped around 2c when doing a full load test on the overclocked settings. (Ben Enos, Enostech.com)

NH-D9L Review

De son côté le NH-D9L proposé pour 50€ dans sa configuration originale en mono ventilateur est un peu en retrait en terme de performances par rapport au précédent. Toutefois il se montrera plus évolutif en cas de changement de processeur pour un modèle plus puissant, avec l'ajout d'un ventilateur supplémentaire.
Test verdict: "Le modèle a privilégier si vous envisagez un configuration plus conséquente mais sans avoir la hauteur disponible ou le budget pour partir sur un modèle en 12 ou 14cm." (Nicolas Henriques, Micougnou.com)

NH-D9L Review

Zejména pak ve spojení s moderními procesory s nižším TDP (včetně 88 W u Core i7-4790K či 91 W u Core i7-6700K) lze i od tohoto chladiče malých rozměrů očekávat tiché uchlazení na základních taktech, ale i solidní výkon pro overclocking.
Test verdict: "Chladič si vede velice dobře, zejména pokud si uvědomíme, jak malé rozměry má a tudíž kam všude půjde vměstnat." (David Ježek, Deep in IT)

NH-D9L Review

Od firmy Noctua otrzymałem do testów dwa chłodzenia procesora, które właśnie przetestuję. Mowa tu o następujących modelach: NH-U9S i NH-D9L. Oba chłodzenia możemy kupić w Polsce i ich cena wynosi odpowiednio około 250 złotych. Jak wypadły coolery w testach?
Test verdict: "Chłodzenia Noctua NH-D9L oraz Noctua NH-U9S to udane konstrukcje, które powinny spełnić oczekiwania większości użytkowników, ponieważ niezbyt duże rozmiary oraz bogaty zestaw producenta powinny zaspokoić apetyty kupujących." (Arkadiusz Byś, PCElite.pl)

NH-D9L Review

To bardzo sensowna, dwuwieżowa konstrukcja, która może zostać zamontowana w ciasnych obudowach. Świetnie prezentowała się we wspominanej Define Nano S na płycie MSI B85i, gdzie wszystkie inne schładzacze blokowały slot PCI-E. NH-D9L może śmiało współpracować z wydajnymi procesorami i5 lub i7, a te pierwsze mogą być odblokowane. Rekordów w OC nie pobijemy, ale możliwe jest już mocniejsze podkręcenie.
Test verdict: "Wydajność NH-D9L robi wrażenie w kontekście niewielkich wymiarów." (Kamil Homziak, blog.PCLab.pl)

How big is the NH-D9L and how much clearance does it provide for RAM and mainboard heatsinks?

Thanks to its 95x95mm footprint, the NH-D9L clears the RAM and mainboard heatsinks on all Intel and most AMD based mainboards, including µATX and ITX. Please refer to the following drawing for the exact measurements and clearance for RAM and chipset coolers:

D15

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.

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.
