Basé sur le célèbre NH-C14

Basé sur le célèbre NH-C14

Bénéficiant de plus de 200 récompenses et recommandations de la part de la Presse internationale spécialisée, le NH-C14 est devenu une référence incontournable parmi les ventirads « top-flow » 140mm à haut rendement. Grâce à un empilage d'ailettes plus profond et son ventilateur NF-A14PWM encore plus performant, cette nouvelle version « S » maintient la performance et accroît la compatibilité.
Conception en C pour un flux optimal

Conception en C pour un flux optimal

La conception optimisée en forme de C du NH-C14S assure un refroidissement silencieux optimal tout en minimisant la hauteur totale comparativement aux ventirads traditionnels 140mm de type tour. Ce design garantit en outre une excellente ventilation des modules de mémoire et des composants avoisinant le socket sur la carte mère.
Montage « faible hauteur»

Montage « faible hauteur»

L'installation d'un seul ventilateur NF-A14 fixé sous l'empilage d'ailettes confère au NH-C14S une hauteur totale limitée à 115mm soit beaucoup moins que les ventirads traditionnels de type tour équipés de ventilateurs 120 ou 140mm ; ce type de montage est ainsi parfaitement adapté à de nombreux boîtiers de bureau / HTPC.
Montage « grand espace »

Montage « grand espace »

L'installation d'un seul ventilateur NF-P14 au sommet du dissipateur permet de laisser un espace aéré plus conséquent sous l'empilage d'ailettes. Ce type de montage offre une parfaite compatibilité avec modules de RAM équipés de dissipateurs thermiques hauts de 70mm ainsi qu'avec les dissipateurs de sockets.
Un design déporté pour un meilleur accès aux emplacements PCIe

Un design déporté pour un meilleur accès aux emplacements PCIe

Comparé au design du NH-C14 original, celui du nouveau NH-C14S offre un double déport axial. Une telle conception lui permet, sur la plupart des cartes mères µATX et ATX, de libérer de l'espace au niveau du dernier emplacement PCIe (les courbures des caloducs font face aux ports PCIe ou au panneau de connectique arrière).*

NH-C14S test

Очевидный плюс NH-C14S – универсальность. Комплектный вентилятор можно установить в нескольких позициях, в зависимости от возможностей корпуса. Также есть потенциал на дальнейший апгрейд. Докупить второй аналогичный вентилятор и все. Второй очевидный плюс NH-C14S – сама конструкция. Кулеры такого типа охлаждают не только процессор, но и околосокетное пространство. Если у материнской платы на самые крупные радиаторы на узле VRM, то дополнительный отвод тепла совсем не лишний. С хорошим разгоном практически обязателен. И напоследок еще о конструкции. Благодаря большому (в 2 мм) расстоянию между ребрами, охладитель эффективен даже при низких оборотах вентиляторов.
Verdict du test: "Там можем ли мы рекомендовать к покупке Noctua NH-C14S? Однозначно ответ да. Это отличный качественный кулер, который принесет определенное удовольствие даже во время распаковки и установки. Более того, нельзя не отметить подход Noctua к клиентам. Если выйдет новый сокет, к которому требуются другие крепежные пластины, то Noctua бесплатно вышлет владельцу кулера новые скобы. Это, согласитесь, приятно." (Oleg Ubeiko, OCClub.ru)

Noctua's NH-C14S is better in every way compared to the original NH-C14. Not only is it more efficient but it also performs much better while being much quieter. The additional heatpipe in the center of the heatsink and the improved NF-A14 fan make a noticeable difference in both cooling and noise performance.
Verdict du test: "We strongly recommend the NH-C14S to anyone who's looking for a high quality top-flow design cooler that will give you fantastic cooling performance while providing high RAM and video card clearance." (Henry Peshkepija, RelaxedTech.com)

NH-C14S test

Noctua liefert mit dem NH-C14S ein Gesamtpaket ab, welches in den Punkten Qualität und Silent-Tauglichkeit außergewöhnlich stark ist. Das im Gegensatz zum NH-D15 geringere Kampfgewicht zollt der Kühlleistung ihren Tribut und so muss der Top-Blow-Kühler seinen Hut vor den Platzhirschen aus der Doppelturmkühlerriege ziehen. Diesen Nachteil kann der NH-C14S aber beim Platzbedarf kompensieren, ohne dass die im Test verwendete und übertaktete Haswell-CPU überhitzte. So kann der kleine aber dennoch 820 Gramm schwere Kühler aus Österreich seine Stärken immer dann ausspielen, wenn die Gehäusebreite oder ein schwer realisierbarer Luftstrom im Gehäuse den Betrieb eines großen und leistungsstärkeren Turmkühlers verhindert.
Verdict du test: "Bei unserem Test des NH-C14S glänzte der Kühler mit einer tadellosen Produktpräsentation und Verarbeitungsqualität mit der sich andere Kühlerhersteller messen müssen. Gepaart mit einem hohen Dynamikbereich des Lüfters erreicht das Produkt mit der markanten Farbgebung unsere Bestnote in Form des Hardware-Factory Gold-Awards. " (Thomas Radigk, Hardware-Factory.com)

NH-C14S test

Au niveau performances, on fait comme pour le D15S, on va lancer un burn du CPU sous SiSoft Sandra, pour une durée de deux heures, températures enregistrées en fichier log au début, après 1h et a la fin. Une fois avec le ventilateur réglé en auto via SpeedFan et une seconde fois, ventilateur bloqué à 100%. Une fois de plus, on peut constater que Noctua tient ses promesses ! Avec une température maximale relevée de 45°c au bout de deux heures de burn et dans boîtier aussi petit, c’est vraiment pas mal du tout ! Il est toutefois vrai qu’avec un CPU au TDP de seulement 55W, la tâche n’était pas ardue, mais au vu du peu de flux d’air possible dans le boîtier, nous n’en n’espérions pas tant !
Verdict du test: "Noctua signe la encore une belle réussite ! Un processeur « relativement » peu encombrant, adapté aux configurations les plus petites (ITX y compris) pour des performances qui n’ont pas à pâlir face aux concurrents !" (Damien Chevalier, MacFay Hardware)

NH-C14S test

През последните няколко години компанията Noctua създаде много сериозно име в IT средите, особено когато става дума за охладители за процесори, или пък вентилатори за монтаж в компютърните шасита. Макар конкуренцията винаги да е била много сериозна, а понякога и доста добре ценово ориентирана, с високото ниво на качество на своите предложения, Noctua съумяха да се позиционират в най-високите нива на производители на споменатите компютърни продукти. Едва ли са много хората, които не са чували за вездесъщият процесорен охладител Noctua NH-D14, който междувпрочем съвсем скоро ще е напълно съвместим с процесорите на AMD с архитектура Zen и Socket AM4, благодарение на новите крепежни елементи, които от Noctua ще раздават (за пореден път) безплатно на всеки потребител, който може чрез документ да докаже, че притежава дънна платка и процесор за Socket AM4, както и разбира се охладител Noctua. Но да не се разсейваме излишно, ами да обърнем внимание конкретно на фокуса на този материал – процесорите Skylake и тяхното охлаждане.
Verdict du test: "Noctua е един от най-сериозните и постоянните производители на процесорни охладители, които присъстват на компютърният пазар и година след година радват своите потребители не само с нови модели охладители, но и с някои специфични “бонус програми”, като например безплатни монтажни елементи за поставяне на по-стари модели охладители върху нови процесорни платформи."

NH-C14S test

Noctua's NH-C14S is definitely impressive since it offers performance almost on par with the NH-D15S, but with better memory clearance. It also has the added bonus of cooling surrounding motherboard components. Like all Noctua coolers, it's very quiet, coming in at just 43 dBA with the fan at maximum RPM. Did I mention that it offers exceptional clearance? Not just for memory since its offset design means it does not interfere with the motherboard's first expansion slot. This makes the NH-C14S a suitable candidate for many mini-ITX and micro-ATX systems, especially with its maximum height of 115 mm in low-profile mode. As expected, build quality is top notch, and installing the NH-C14S is a breeze with Noctua's tried and tested SecuFirm 2 mounting system. Add in the solid packaging, a good accessories bundle, and an awesome warranty, and you end up with a very attractive product.
Verdict du test: "If you do prefer a C-type design cooler that cools more than the CPU and need top-tier performance with no noise, the NH-C14S may just be what you are looking for." (Raymond Lemar, techPowerUp.com)

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.

I can't open the socket due to the mounting bars!

Please first loosen one of the two thumbscrews that hold the mounting bars in place. Then untighten the second screw so that you can swivel the mounting bar and open the socket. Depending on the position of the mounting bars, you may need to swivel both.

Does the package include a backplate for AMD AM2(+)/AM3(+)/FM1/FM2(+)?

No. As most AMD mainboards come with a stock backplate preinstalled, the cooler doesn’t include an AMD backplate. If your mainboard doesn’t have a backplate, please contact our support team at support@noctua.at.

amd backplate

How can I check whether my AMD mainboard has a standard AMD backplate that’s compatible with the SecuFirm2™ mounting system and how should I proceed with the installation?

The SecuFirm2™ mounting system requires a standard AMD backplate (either plastic or metal) with screw threads as shown on the pictures below. These backplates are pre-installed on the rear side of most AMD mainboards (see first picture below) and fixed to the retention module with four screws (see second picture below). If your retention module is fixed with plastic bolts instead of metal screws, please contact support@noctua.at in order to obtain an appropriate backplate.

In order to proceed with the installation of your Noctua cooler, please remove the four screws and the retention module but keep the backplate in place so that you can see the screw threads from the top side of the motherboard (see third picture below). You can then proceed with the installation of the SecuFirm2™ mounting kit as described in the manual (see fourth picture 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 the cooler compatible with the LGA2011-3 socket?

Yes. Due to the heatsink mounting mechanism being identical on LGA2011-0 and 2011-3, the cooler supports both types of LGA2011-3.

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.


    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.

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.

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

Systems from Acer, Dell, HP or Lenovo often use motherboards which differ slightly from the specifications issued by Intel and AMD. While those changes are usually subtle, they can led 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 can often not be resolved.

Due to the large number of possible issues with systems from Acer, Dell, HP and Lenovo, which can't be resolved with different mounting parts alone, Noctua does not officially support such machines.

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).

How big is the NH-C14S and how much clearance does it provide for RAM and mainboard heatsinks?

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

C14S

Is the cooler compatible with the LGA1151 socket?

Yes. Due to the heatsink mounting mechanism being identical on LGA1150, LGA1151, LGA1155 and LGA1156, the cooler also supports LGA1151.

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

The supplied backplate is for LGA115x only and there is no backplate required for installation on LGA2011. Please refer to the installation manual for how to install the heatsink on LGA2011.

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.

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:

Base Protection Cover

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.

Should I take the cooler off before transporting my system?

As it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, for safety reasons, taking the cooler off. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the heatsink installed.

Are there any concerns using Noctua CPU coolers on Intel Skylake (LGA1151) CPUs?

Our SecuFirm2™ mounting systems undergo comprehensive compatibility tests before being approved for new platforms. We have neither detected any problem with regard to the Intel LGA1151 platform (“Skylake”) during these tests nor have we received any reports from our customers, sales partners and system integrators that would indicate any possible issue. Our SecuFirm2™ mounting systems (with the exception of some compact L-type models) rely on coil springs to create the required contact pressure, which gives a certain flexibility both with regards to tolerances in stackup height and shocks or other forces. Compared to spring-less mounting systems, which exclusively rely on the bending of the mounting brackets in order to create contact pressure, this allows to reduce the mechanical stress on CPU, socket and motherboard and thus helps to prevent possible damage from excessive forces. However, as it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, due to safety reasons, to take off coolers with a total weight of more than 700g (incl. fan).

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.

Pourquoi le fond du refroidisseur Noctua n'est-il pas brillanté et poli ?

Etant donné que la plupart des enthousiastes d'ordinateurs personnels utilise encore aujourd'hui des pâtes thermiques à forte viscosité, le fond du refroidisseur Noctua a été optimisé pour l'utilisation de ces pâtes. Les fines rainures (micro-grooves) dans la surface du fond du refroidisseur Noctua permettent d'appliquer les pâtes thermiques à forte viscosité de manière homogène en une couche ultramince et sans aucune inclusion d'air n'existe entre le refroidisseur et la processeur central. Le risque d'une application non homogène serait beaucoup plus élevé si la surface était brillantée et polie. Des couches de pâte thermique trop épaisses et des inclusions d'air altérant sensiblement la transmission calorifique, les micro-rainures sont d'une importance décisive pour la performance de refroidissement totale du refroidisseur Noctua en cas d'utilisation des pâtes thermiques courantes à forte viscosité.

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
