NH-L12S Opinión

Was die Lautstärke betrifft, schenken die beiden sich nicht viel. Auffällig ist, dass beide Lüfter sich erst ab ca. 50 % ihrer maximalen Drehzahl von der Raumlautstärke abheben. Das sind bei dem NH-L12S 1080 U/min und bei dem NH-L9a-AM4 sogar 1550 U/min. Lüfter von anderen Herstellern sind bei dieser Drehzahl in der Regel deutlich zu hören.
Resultado del análisis: "Noctua steht für Qualität und das zeigen diese beiden Kühler. Die Verarbeitung ist von der Verpackung bis hin zur kleinsten Schraube absolut erste Klasse. Ein cleveres Konzept sorgt für einen einfachen Einbau der Kühler." (Robin Wibberg, hardwareinside.de)

NH-L12S Opinión

Noctua NH-L12S is a CPU cooler which I was really eager to test and review since I was very impressed by the cooling capabilities of its ancestor NH-L12 tested and reviewed back in the days. The new model offers a lot of improvements and that includes tighter dimensions, better cooling fan and most of all wider range of supported sockets and processors. You see, in low profile or HTPC systems everything really counts since the smaller rigs lack of space, so offering same or better performance, better compatibility or lower noise level and at the same time with smaller dimensions means really a lot. The cooler itself is with really tiny dimensions and still it is capable to provide very, very good cooling result and maintain my processor running stable and pretty quiet through the test, which I was able to perform. According to what I saw, I believe this cooler is a very good choice to work with low and average grade processors working at normal frequencies with some serious load for a lot of time even inside small form factor or HTPC systems. For overclocking it might not be the best option especially with processors of about 125W by default. For these scenarios there are other products.

NH-L12S Opinión

Como en la mayoría de sus productos, Noctua nos sorprende con un productos de grandísima calidad y unos resultados que has de verlos para creerlos, un disipador de pequeñas dimensiones disipando a bestias de la computación como ryzen 7 e i7s es posible con este pequeño modelo. Es uno de los pocos modelos que nos han sorprendido gratamente por lo que pensábamos que podría hacer y lo que ha llegado a hacer, podemos encontrarlo ahora mismo en Amazon por 50€ precio muy similar a otros modelos de la marca, pero para el pequeño tamaño que tiene disipa casi igual que el legendario NH-U12S. Por todos estos motivos le otorgamos a este disipador de Noctua NH-L-12S el galardón de Platino de Tecnogeekies.
Resultado del análisis: "El disipador de Noctua de bajo perfil con un increíble rendimiento." (Ignacio Merino Arnaiz, TecnoGeekies.com)

NH-L12S Opinión

Für die knapp 50€, die für den NH-L12S zu Buche schlagen, bekommt man einiges geboten. Mit 70mm Einbauhöhe schlägt sich der Kühler im Testfeld gut. In gut belüfteter Umgebung dürften selbst Prozessoren mit 8 und mehr Kernen noch recht gut im Griff zu halten sein; für den Betrieb eines Mittelklassemodells in einem ITX-Gehäuse ist der Kühler auf jeden Fall ausreichend. Die Lautstärke bleibt dabei immer angenehm, Lagergeräusche sind nie zu vernehmen. Bei der Montage erhält man das von Noctua gewohnte Paket: Das altbewährte SecuFirm2 funktioniert auch beim NH-L12S perfekt und ohne Kritikpunkte. Beim Zubehör zeigt sich der Hersteller ebenso, wie gewohnt, großzügig: Ausreichend Wärmeleitpaste und ein Vorsteckwiderstand liegen genauso bei wie der dünne Schraubenzieher, der bei der Installation hilfreich ist. Bei der Verarbeitungsqualität bestätigt sich der sonstige Eindruck: Durchgehend saubere Ausschnitte und Fräsungen, optisch aufgewertet durch die gut gelungene Vernickelung. Hier lässt sich nichts wirklich kritisieren, abgesehen von dem Fehlen von Heatpipe-Abdeckungen.
Resultado del análisis: "Alles in Allem ist der NH-L12S zweifellos ein guter Kühler für große und kleine (ITX-)Systeme, der durch sehr gute Verarbeitungsqualität, viel Zubehör und dank zahlreicher Montageoptionen auch mit viel Flexibilität auftrumpfen kann." (Valentin Sattler, TweakPC.de Forum)

NH-L12S Opinión

Noctua рекомендует NH-L12S для HTPC и систем малого форм-фактора (SFF), но только для работы CPU на штатных тактовых частотах и с TDP не выше 95 Вт. Как и можно было ожидать, кулер охлаждается вертикальным воздушным потоком. Однако по производительности охлаждения ему удалось нас удивить. Noctua заменила два вентилятора предшественника одной довольно тонкой 120-мм моделью, поэтому кулер NH-L12S обеспечивает отличную гибкость установки. Вентилятор можно монтировать как под радиатором, так и над ним. В последнем случае освобождается больше пространства для планок памяти. Штатный вентилятор отличается широким диапазоном скорости вращения, на низкой скорости он работал едва слышно. Но даже на максимальной скорости уровень шума оставался вполне приемлемым. Даже с комплектным узким вентилятором NH-L12S показал хорошую производительность охлаждения, заметно выше, чем у многих конкурентов со сравнимым дизайном. Но, как показал наш тест с эталонным вентилятором, установка вентилятора стандартной толщины может еще увеличить производительность охлаждения. В целом, кулер с вертикальным воздушным потоком без проблем справился с охлаждением нашего Core i7-4790K на штатных тактовых частотах. Причем с умеренной скоростью вращения вентилятора и низким уровнем шума.
Resultado del análisis: "Если вам нужен компактный и качественный кулер с вертикальным воздушным потоком и сравнительно хорошей производительностью охлаждения, то на Noctua NH-L12S стоит обратить внимание." (Дмитрий Чеканов, Hardwareluxx.ru)

NH-L12S Opinión

Önce fiyattan başlayalım. Ürünün Türkiye fiyatı 294 TL. Bu fiyata giriş seviyesi 120MM radyatörlü sıvı soğutma sistemler alınabilir. Ama bu soğutucu kasa ve anakart yüzünden yer sıkıntısı çekenlere hitap ettiği için NH-L12S'yi daha çok yatay olarak tasarlanmış HTPC soğutucularla karşılaştırmada fayda var. Boyut açısından Türkiye'de yer alan rakipleri PH-TC12LS, Xigmatek CAC-EXAI6-U01 Janus, Deep Cool Gabriel. Fiyat aralıklarıysa 190-220 TL civarında. Ama bu soğutucuların hiçbiri tam olarak NH-L12S ile karşılaştırılamaz. Çünkü NH-L12S daha kaliteli bir fana sahip, daha geniş ısı yayım alanı var, daha kaliteli bir macun kullanılıyor, blogun ve lehimlerin inşa kalitesi daha yüksek, kutu içeriği daha zengin ve daha iyi teknik destek duruyor. Bu noktada rakiplerinin tek avantajı fiyatları oluyor. Bu durum Noctua'nın diğer ürünleri içinde geçerlidir genelde. Fiyat bakımından hiçbir zaman rekabetçi konumda değildirler. Belirli bir kalitelinin altına inilmediği için bu durum zorunluluk olarak da görülebilir. Kullandığım en sesli Noctua soğutucu NH-L12S bu oldu. Bunun nedeniyse soğutucunun slim fanla geldiği için ısıyı uzaklaştırmada daha yüksek fan devrine ihtiyaç duyması. Bu devirlerde ve bu boyutta bir fanda gelmesi gerekenden daha fazla bir ses gelmiyor. Noctua bunu düşünerek kutu içeriğine L.N.A adaptör koymuş fan adaptörle devri 1400 RPM'e indiği zaman ses kabul edilebilir seviyeye geliyor. Hatta ben olsaydım sürekli adaptörle kullanırdım çünkü 1800 RPM'den 1400 RPM'e düşüşse yaşanan sıcaklık artışı dikkate alınacak bir seviyede değil. NT-H1'den ekstra bahsetmeye gerek bile yok. Kutu içeriğinden çıkabilecek en iyi macun. Montaj kiti yine her zamanki gibi. İsterseniz yüzlerce defa montaj yapın ama tüm somun ve vidalarda hiçbir gevşeklik hissi olmadan ilk günkü gibi kalacaktır. Bunun başlıca nedeniyse plastik parça olmaması. Performans kısmında maalesef veri tabanımı kaybettiğim için çok net bir şekilde konuşamıyorum ama soğutucu performansı hemen hemen NH-L12S ile yakın. C14S ile karşılaştırdığımda yüksek fan devirlerde pek bir fark yok fakat 600 RPM ye düştüğümüzde C14S 4 derece kadar daha iyi. Hatta bu durumu kontrol etmek için başka incelemelere baktım ve işlemci 130W TDP olmasına rağmen normal fan devirlerinde C14S 3 Derece iyiyken fan devri düşürüldüğünde fark 8 dereceye çıkıyor. Yani başta testlerde de elde edilen sonuç benimkilere oldukça yakın. Boyut olarak C14S baya bir büyük olmasına rağmen performans anlamında o kadar fark yok. Bu boyutlarda sunduğu performans son derece yeterli, hatta hız aşırtma bile rahatlıkla yapabilirsiniz.
Resultado del análisis: "Diyeceğim o ki ufak boyutlara sahip etkili performans sunan bir soğutucu arıyorsanız NH-L12S piyasada bulunabilecek alan-performans açısından en mantıklı soğutuculardan." (Ali Emre Alıcı, Donanimhaber Forum)

NH-L12S Opinión

Mit dem neuen NH-L12S erwirbt man einen Noctua mit klassischen Kernpunkten: hochwertige Verarbeitung und hohe Kühlleistung. Auf unserem Testsystem überzeugte er selbst unter dauerhafter Vollauslastung der CPU durchgehend mit sehr guter Kühlleistung. Auf einem i5-6600 mit lediglich 65W TDP fühlte er sich sogar leicht unterfordert – hier besteht also noch genug Leistungsreserve für Prozessoren mit mehr Wärmeabstrahlung. Für Frischluft sorgt der beiliegende NF-A12x15 PWM -Lüfter, der mit einer ausgeprägten Laufruhe auffällt und selbst bei hohen Drehzahlen nie aufdringlich wird. In Verbindung mit dem im Lieferumfang enthaltenen Low-Noise-Adapter (LNA) würde man den Lüfter selbst bei 100% kaum aus einem Gehäuse hören – perfekt für Silent-Freunde. Die Verarbeitung des komplett vernickelten Kühlers ist wie gewohnt durchgehend auf hohem Niveau, scharfe Schnittkanten oder ähnliches waren nicht vorhanden. Mit rund 49,- € (Stand 16.11.2017) ist der Kühler nicht günstig, allerdings bekommt man von Noctua gewohnte Premiumqualität mit sechs Jahren Garantie.
Resultado del análisis: "Mit seiner Bauhöhe von gerade mal 70 bzw. ~85 Millimetern (je nach montierter Lüfterposition) überzeugt der NH-L12S mit seiner Kombination aus Qualität, guter Kühleffizienz und einem sehr leisen Lüfter, wodurch er eine empfehlenswerte Alternative für Gaming- oder Arbeitsrechner in kompakten Gehäusen ist."

NH-L12S Opinión

No olvidemos que estamos ante dos disipadores tipo concha y de perfil bajo, por lo que están diseñados principalmente para PCs de salón o HTPC pues normalmente se va a usar en cajas de pequeño tamaño y en general en PCs de factor de forma pequeño. Esto significa que este tipo de disipadores no está diseñado para trabajar con procesadores con un TDP muy alto y tan calientes como el actual Ryzen 1800X y sus 16 hilos. Por tanto, aunque el 1800X no es el procesador objetivo de este tipo de disipadores si lo podemos considerar como una buena piedra de toque y sin duda, ambos disipadores (aunque con dificultades en el caso del NH-L9a-AM4) han sido capaces de soportar una difícil sesión de Linx con el propio procesador overclockeado hasta los 4 Ghz.
Resultado del análisis: "Por supuesto que no estamos ante los disipadores más eficiente de Noctua, pero su reducidísimo tamaño hacen de estos dos disipadores, dos valores muy a tener en cuenta en PCs de pequeño o mediano tamaño ideal para HTPC o incluso PCs de juegos no demasiado exigentes."

NH-L12S Opinión

When the NH-L12 low-profile CPU cooler was launched just over 5 years ago it was the only of its kind to feature two premium fans one 120mm (NF-F12) at the top and one 92mm (NF-B9) one at the bottom so performance although not stellar was far better compared to similar compact solutions. The only tiny drawback (if you can even call it that) the NH-L12 had was its height which with the top 120mm fan mounted came up to 93mm. The easy way to resolve that was to remove the top 120mm fan (in which case the height of the cooler fell to 66mm) but the bottom 92mm fan alone was not nearly enough to produce satisfying results (at least not when tested with our test rig). Since the new NH-L12S replaces the NF-B9 fan with Noctua's latest NF-A12x15 slim 120mm premium fan however it should offer better cooling efficiency.
Resultado del análisis: "Sure there are many low-profile CPU coolers that cost less than the NH-L12S but you will have a really hard time finding one that combines its size, quality noise levels and performance which is also why we give it our Golden Award." (Nik Kastrantas, NikKTech.com)

NH-L12S Opinión

Dans notre test nous avons utilisé un processeur avec un TDP dans les limites hautes préconisées par Noctua, il s'en sort très bien, nous avons même été en mesure de pousser notre processeur en overclocking et dans ce cas nous sommes bien hors des limites fixées par Noctua. la position du ventilateur n'a que peu de conséquences sur l'efficacité du ventirad. La discrétion est de mise sauf peut être en usage extrême, nous ne le critiquerons pas la dessus car ce n'est pas sa destination. Noctua NH L12SLe montage est simple et très détaillé, la compatibilité est assurée sur les sockets du moment, il n'y a pas d'incompatibilité notoire sauf évidemment les barrettes mémoire, deux montages du ventilateur sont donc possibles.
Resultado del análisis: "Le Noctua NH-L12S est un ventirad de très bon niveau, il a été conçu à la base pour dissiper du mieux possible avec un niveau sonore réduit et un encombrement minimum pour être installé dans un mini-boîtier, pari réussi." (Philippe Vautier, 59hardware.net)

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

NH-L12S dimensions

I'm experiencing fan speed issues with my motherboard from Supermicro, what can I do?

The BIOS of many motherboard models from Supermicro expects a certain minimum fan speed (usually 700rpm), which is higher than the minimum fan speed that can be achieved with Noctua's PWM fan models. The BIOS may interpret the low minimum RPM of Noctua fans as a fan error and thus try to run the fan at 100% for a short period before going back to automatic control.. This can result in oscillating fan speeds and fan speed warnings in the BIOS or the fan management console.

Unfortunately there is usually no option to set a lower minimum value that would suit the low minimum speed of Noctua PWM fans.The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply).

Why doesn't the supplied backplate fit my LGA2066 / LGA2011 motherboard?

The supplied backplate is for LGA115x only and there is no backplate required for installation on LGA20xx (LGA2066, LGA2011-3, LGA2011-0). Please refer to the installation manual or our installation video for how to install the heatsink on LGA20xx.

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.

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.

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:

NH-C14S
NH-D14 SE2011
NH-D15
NH-D15S
NH-D9L
NH-L12
NH-L9x65
NH-U12S

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.

How much RAM clearance does the NH-L12S provide?

In high-clearance mode (with the fan installed on top of the fin-stack), the NH-L12S can be used with RAM of up to 48mm including heat-spreaders. In low-profile mode (with the fan installed underneath the fin-stack), the NH-L12S supports standard height memory modules with up to 35mm height.

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.

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.

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.

Orientation

How can I check whether my case is wide/high enough for the cooler?

Most case manufacturers provide specifications for maximum CPU cooler height/clearance. Please refer to these specifications in order to verify that the cooler will fit the case. If no specifications are available, please contact the case manufactuer or measure the distance from the motherboard tray to the side panel (tower cases) or top panel (desktop cases). If this distance is bigger than the height of the cooler + 15mm (mainboard spacers + mainboard + CPU), the height/width of your case should be sufficient.

How to remove the base protection cover?

Noctua CPU coolers are shipped with a plastic protection cover at the bottom side of the cooler, which protects the contact surface against scratches and other damage.

The base of Noctua CPU coolers is made from hard-wearing nickel plated copper, so there's nothing to worry about if you buy a Noctua cooler from second hand or if your cooler didn't come with a protection cover. Please proceed with the installation as explained in the manual.

You can simply remove the cover as shown below:

I get a CPU fan error using my Noctua PWM fan, is it faulty?

Noctua PWM fans feature a minimum speed of 300rpm to allow for ultra quiet operation when your CPU is at idle state and doesn’t require higher cooling performance. Some mainboards display error messages such as “CPU fan error” during the booting process when the fan speed is below a certain level. If you get such error messages using your Noctua PWM fan and if such options are available in your BIOS, please either adjust the minimum fan speed monitoring limit to 200rpm or increase the minimum PWM duty cycle. If your BIOS doesn’t offer these options, please disable CPU fan errors. For detailed information on BIOS fan settings, please consult your mainoard’s manual or contact your mainboard manufacturer.

Does the mounting-system support LGA2011 based Xeon CPUs?

There are two different types of ILM (Independent Loading Mechanism) for Intel’s LGA2011 based Xeon CPUs: Square ILM with 80x80mm hole spacing and Narrow ILM with 56x94mm hole spacing. The Square ILM socket is mechanically identical to the LGA2011 socket for Core i7, so the mounting-system is fully compatible, but it is not compatible with Xeon mainboards that use the Narrow ILM:

Xeon Compatibility

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.

Why is the cooler’s contact surface slightly convex?

As the Integrated Heat Spreaders (IHS) of today’s CPUs are slightly concave, the cooler’s contact surface has been deliberately designed to be slightly convex in order to ensure optimal contact. This way, more contact pressure will be applied at the centre of the IHS directly above the DIE, which results in better heat transfer and improved overall performance.

Is the cooler compatible with LGA775 and LGA1366?

The cooler does not support LGA775 and LGA1366 out of the box, but can be made compatible using the NM-I3 mounting kit. Noctua provides the NM-I3 kit free of charge if a proof of purchase (scan, photo or electronic copy of the invoice) of the cooler and an LGA775 or LGA1366 motherboard or CPU are presented. In order to install the cooler using the NM-I3 kit, please first unscrew the center screw of the original one-piece fastening bracket (you can reach through the fin stack using the long screw driver supplied with the cooler) and remove it. Then install the two fastening brackets of the NM-I3 kit as described in the NM-I3 installation manual.

I’ve used all the NT-H1 thermal compound that came with the cooler, can you send me more?

Please kindly note that the NT-H1 thermal compound supplied with our coolers is a consumable item so our manufacturer’s warranty does not include providing additional thermal compound. You can purchase NT-H1 from our resellers.

Which sockets are supported or can be supported using upgrade kits?

Please refer to our socket compatibility chart.

Is it a problem that the CPU heatspreader is not covered completely by the heatsinkbase on LGA2011-3?

No. Depending on the orientation of the cooler, 1-2mm at the outer edge of the heatspreader may not be covered by the heatsink base. As the heat is concentrated at the center of the CPU and the outermost parts are irrelevant for heat-transfer, this is no problem at all.

My Noctua PWM fan starts to spin when the PC boots but then stops, what is wrong?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). In this case, it may occur that the mainboard reduces the voltage so much that the fan stops. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.



To resolve the issue, you can:

  1. Choose a higher fan speed profile in the BIOS (e.g. „normal“ instead of „silent“, etc.) or deactivate automatic fan speed control and use a Low-Noise Adaptor instead.

  2. Use the mainboard‘s fan speed control software or 3rd party tools like Speedfan to regulate the fan speed. Unlike BIOS based fan speed control, the supplied software usually checks whether the fan has stopped and increases voltage accordingly or at least offer more options to set up the fan properly.

  3. If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?

The specified minimum speed refers to the speed at 20% PWM duty cycle. There can be several reasons why the fan doesn‘t go as low as indicated:

  1. Many mainboards do not go below 40%, 50% or even 60% PWM duty cycle on case fan headers. Please refer to your mainboard manual to verify whether the fan header actually goes down to 20% duty cycle. If that's not the case, in some cases you can use the fan speed control software supplied with your mainboard to overcome these limitations and reduce the fan speed even further. However, 3rd party tools like SpeedFan offer greater flexibility and better options to work around the limitations imposed by the mainboard vendors.

  2. Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

    4 pin fan header types

    Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

    Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

    Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.

¿Por qué la base de los disipadores Noctua no tiene un acabado pulido como un espejo?

Teniendo en cuenta que mayoría de los entusiastas del hardware usan compuestos térmicos de alta viscosidad, la superficie de la base de los disipadores Noctua se ha optimizado para el uso de este tipo de pastas térmicas. Las micro-hendiduras de la superficie de la base de los disipadores Noctua aseguran que los compuestos térmicos de alta viscosidad se dispersen de manera uniforme en una fina capa por toda la zona de contacto y que no queden huecos entre el disipador y la CPU. Con un acabado pulido como un espejo, el riesgo de una dispersión desigual es mucho más alto. Dado que las capas demasiado gruesas de pasta térmica y los huecos con aire deterioran dramáticamente la transferencia térmica, las micro-hendiduras son de vital importancia en el rendimiento general de los disipadores Noctua cuando se usan con compuestos térmicos de alta viscosidad.
