120/92mm dual fan design

120/92mm dual fan design

Thanks to its exquisite dual fan setup consisting of Noctua's highly optimised NF-F12 (120mm) and NF-B9 (92mm) premium fans, the NH-L12 pushes the bar in terms of low-profile quiet cooling performance.
Extra-low profile in 92mm single-fan mode

Extra-low profile in 92mm single-fan mode

The NH-L12 can be used with the NF-B9 92mm fan only in order to reduce the overall height to 66mm. This way, the cooler is suitable for many typical µATX or Mini-ITX enclosures and ideal for whisper-quiet HTPC systems.
PWM support and Low-Noise Adaptors

PWM support and Low-Noise Adaptors

The NH-L12's NF-F12 and NF-B9 fans support PWM for convenient automatic speed control. In addition, the maximum fan speed can be reduced to 1200/1300rpm using the supplied Low-Noise Adaptors for even quieter operation.
SecuFirm2™ mounting system

SecuFirm2™ mounting system

Noctua's enthusiast grade SecuFirm2™ multi-socket mounting provides broad socket compatibility (LGA 2011, LGA1366, LGA1156, LGA1155, LGA1150, LGA775, AM2, AM2+, AM3, AM3+, FM1, FM2, FM2+) and meets the highest demands in safety, performance and ease-of-use.
Mini-ITX mounting without backplate

Mini-ITX mounting without backplate

Some Intel based Mini-ITX mainboards don't allow for the installation of backplates. The NH-L12 thus comes with an extra set of Intel mounting bolts which make it possible to install the cooler without using the SecuFirm2™ backplate.
NT-H1 thermal compound

NT-H1 thermal compound

Noctua's much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.

NH-L12 Review

Möchte man aber sein System auf möglichst kleinem Raum möglichst leise haben, dann spielt der Noctua NH L12 seine Stärken aus; Low Noise Adapter und erstklassige Lüfter machen ihn, selbst in hitzigen Situationen, nahezu lautlos. Ob der Noctua mit seinem beige/braunen Lüftern zu gefallen weiß, darf jeder für sich entscheiden, aber was den Kompromiss aus Leistung, Lautstärke und Größe angeht, hat er definitiv den meisten Konkurrenten die Nase vorn.
Test verdict: "Der Noctua erhält auf Grund der geringeren Größe und der sehr geringen Lautstärke den Silent Award." (Dominik Arnold, hardwareinside.de)

NH-L12 Review

The coolers that really grab our attention in this test are the same ones that triumphed at idle: the Noctua NH-L9x65 and NH-L12, along with the SilverStone AR06. They offer excellent thermals (for their respective sizes), along with very good noise levels.
Test verdict: "Winning the award for the best high-performance low-profile cooler is the 93mm-tall Noctua NH-L12." (Ari Altmann, The Tech Buyer's Guru)

NH-L12 Review

NH-L12 posiada dwa wentylatory w zestawie, co dosyć rzadko trafia się w takich zestawach oraz ukierunkowane wydmuchiwanie powietrza, a NH-C14S posiada wygląd, przypominający literkę „C”, który ma poprawić jego wydajność.
Test verdict: "Chciałbym, czy też nie, to i tak muszę znowu pochwalić produkty tej firmy. Jakość wykonania i bogaty zestaw, jak zwykle robią na mnie spore wrażenie. Testy wydajnościowe również wypadają bardzo dobrze, a innowatorskie rozwiązania dopełniają całości." (Arkadiusz Byś, PCElite.pl)

NH-L12 Review

In dual fan mode, the NH-L12 easily trades blows with the Scythe Big Shuriken 2 Rev B, our best performing downdraft cooler that we have tested until now. Even in single fan mode, the performance is not to be sniffed at, being the 4th best cooler in our test database in this mode. No weird sonic anomalies were present during testing, and the cooler kept a nice, low, tonal note throughout.
Test verdict: "[T]he performance is fantastic, besting the Scythe Big Shuriken 2 rev B in dual fan mode, and only slightly under-performing it in single fan mode. This does come with a height penalty, however, but for the ultimate in downdraft cooling, this may be your best bet based on our testing to date." (John Morrison, SmallFormFactor.net)

NH-L12 Review

The Noctua NH-L12 is the best performing cooler in both setups averaging at 65 °C / 53 °C. This was somehow expected due to the coolers dimensions and its dual fan setup.
Test verdict: "Do you have a lot of place, a powerful CPU, want the best performance, the most premium accessories, comfortable installation and budget is not an issue? Then the Noctua NH-L12 is probably the one for you. It’s big with a dual fan setup and it will give you great performance with the possibility to alter the height by choosing the fan setup."

NH-L12 Review

Con todas las ventajas del fabricante (impecables acabados, rendimiento fuera de toda duda dado su perfil, versátil, con control por PWM, montaje fácil y seguro...), Noctua le suma al NH-L12 la posibilidad de colocar dos ventiladores activos, de 9 y 12 centímetros, para maximizar efectos, y personalizar así la experiencia, ya que el NH-L12 es capaz de amoldarse a cualquier entorno. Con todo, el único pero es que se trata de un disipador pequeño y, por lo tanto, no está preparado para procesadores con TDP muy alto, y mucho menos para overclock, tal y como hemos visto, así que ya sabemos a qué atenernos. Con todo, podemos encontrarlo a la venta por un precio aproximado de 50 euros. Como solemos hacer, les otorgamos al Noctua NH-L12 el Premio N3D Recomendado.
Test verdict: "¿Qué podemos decir de Noctua que no sepamos ya? Pues que nos aporta el rendimiento, la estabilidad y la seguridad que le debemos pedir a un disipador por aire. Desde siempre hemos estado muy contentos con lo que Noctua hace por nuestras CPUs, y esa calidad sigue presente a día de hoy." (Iván Aparicio, Noticias3D.com)

NH-L12 Review

Несколько лет назад мы уже рассматривали кулеры этой компании — NH-D14 и NH-C14, и надо сказать что с тех пор в ассортименте Noctua моделей прибавилось. Однако, в целом, новые модели во многом повторяют своих предшественников, и объяснение этому достаточно, простое. Эти кулеры изначально спроектированы правильно! Да, безусловно, стоимость моделей Noctua выше, чем у аналогичных кулеров других производителей, но, покупая их, пользователь может быть уверен, что данная система охлаждения будет служить верой и правдой очень долго без всяких нареканий.
Test verdict: "Согласно результатам нашего исследования, мы считаем, что среди всех представленных в этом обзоре решений для охлаждения топовых процессоров лучшим является кулер Noctua NH-D15S. Для небольших корпусов и производительных процессоров оптимальным решением станет Noctua NH-C14S, который успешно продолжил успех своего прародителя Noctua NH-C14. Флагманский процессорный охладитель Noctua NH-D15 подойдет всем любителям разгона и просто состоятельным пользователям. Наше тестирование не предполагало разгон процессора, но это основная задача для таких кулеров, и нет ничего удивительного в том, что эта система охлаждения выбилась в лидеры. Еще одну модель с двумя вентиляторами — Noctua NH-L12, можно отнести к универсальным компактным решениям для малых корпусов." (Максим Афанасьев, ixbt.com)

NH-L12 Review

Noctua liefert mit dem NH-L12 einen weiteren CPU-Kühler in gewohnter Premiumqualität für gehobene Ansprüche. Die Verarbeitung ist sehr gut, die Kompatibilität in allen Belangen lobenswert und das Montagekonzept wurde einwandfrei umgesetzt. Die Leistung des Low-Profile Kühlers ist mit einem minimalen thermischen Widerstand von 0,168 K/W bei einem Schalldruckpegel von 54,6 dB(A) gut, sodass teilweise sogar massemäßig überlegene Kontrahenten am Markt einpacken können.
Test verdict: "Jeder Interessent, der auf der Suche nach einem kleinen aber dennoch potenten CPU-Kühler ist, sollte den NH-L12 auf alle Fälle in seine engere Auswahl nehmen. Wir können den Noctua NH-L12 bedenkenlos empfehlen!" (Tobias Mann, PCMasters.de)

NH-L12 Review

Tenemos en nuestras manos un gran disipador, a la altura de los productos que nos presenta Noctua, que nos permitirá controlar la temperatura del procesador aunque el equipo sea compacto. Además, gracias a su reducido tamaño, permitirá usar el slot PCIe situado bajo el procesador.
Test verdict: "Noctua con su NH-L12 ha conseguido un disipador muy versátil, ya sea con la configuración de doble ventilador o la de un solo ventilador para conseguir un bajo perfil, el NH-L12 se comporta adecuadamente en ambos casos." (Miguel G. Mingorance, GameIT.es)

Installation Manual (PDF)

Information Sheet (PDF)

In which orientation should top-flow coolers (NH-C series, NH-L12) be installed?

When using top-flow coolers in a tower-style case, we strongly recommend installing the cooler with the heatpipes in horizontal position or with the bends of the heatpipes pointing downwards. Please avoid installing the cooler with the bends pointing upwards as this may result in reduced cooling performance. In desktop cases, the cooler can be used in any orientation.

How big is the NH-L12 and how much clearance does it provide?

Please refer to the following drawing for the exact measurements and clearance:

P14

Is it possible to install the supplied NF-F12 or other 120mm fans underneath the fin stack?

The NF-B9 92mm fan is used underneath the fin stack because it gives easy access to the mounting screws and sits within the 95x95mm (Intel) and 96x114mm (AMD) keep-out zones, thus providing full compatibility with standard height RAM and chipset/VRM heatsinks. In principle, it is also possible to put the supplied NF-F12 120mm fan underneath the fin stack instead, but in many cases, this setup will cause compatibility issues with RAM and/or chipset/VRM heatsinks. Similar issues are likely to arise with other 120mm fan models and in addition, some fans may be blocked by the mounting screws and/or block access to the screws. As a result, using 120mm fans underneath the fin stack may be possible in some cases, but is not officially supported.

Is the NH-L12 compatible with the LGA2011-3 socket?

The NH-L12 features a special variant of the SecuFirm2™ that needs to be updated with the new NM-IPS2 spacers in order to be compatible with LGA2011-3. NH-L12 owners can now request these spacers free of charge here.
