Digne successeur du célèbre NH-C14, le NH-C14S est un ventirad « top-flow » (flux vertical) pour CPU hyper puissant bénéficiant d’une grande compatibilité et modularité. Grâce à son empilage d’ailettes plus profond et à l’intégration du fameux ventilateur NF-A14 PWM, le modèle simple ventilation NH-C14S assure le même niveau de refroidissement que son prédécesseur équipé de deux ventilateurs en offrant même une flexibilité accrue : L’installation du ventilateur au sommet du dissipateur assure une compatibilité avec les modules de RAM pouvant atteindre 70mm de hauteur. L’installation du ventilateur sous le dissipateur assure une parfaite compatibilité avec de nombreux boîtiers HTPC grâce à une hauteur totale du ventirad n’excédant pas 115mm. Par ailleurs, la conception déportée permet de dégager le dernier emplacement PCIe sur la plupart des cartes mères µATX et ATX. Complété du système de fixation haut de gamme multi-sockets SecuFirm2™, de la célèbre pâte thermique NT-H1 Noctua et assorti d’une garantie fabricant totale de 6 ans, le NH-C14S est une solution « top-flow » haute performance et de grande qualité pour les plus exigeants.

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

So as we can see, the Noctua NH-C14S does have a pretty good performance. At a room temperature of 28C, the I5 6600K reached a minimum average temperature of 30C while near 63C on load. I feel pretty relaxed when I say I’m good with those temperatures at the stock speed, but a little concerned with the overclocked temperature because my overclocked test is a bit overkill at 1.344 Vcore voltage. When it comes down to overclocked performance, we saw a good gain on the max temperature reaching 85C. Now compared to a liquid cooler, even if an AIO, but a 360mm AIO with 3x 120mm fans, the temperature seems justified considering it’s only air cooler and is only powered by 1/2 fan(s). We didn’t have an air CPU cooler to compare against the Noctua C14S, but even when compared to the 360mm AIO cooler, the comparison doesn’t seem unfair as the C14S is not lacking behind by a huge lead. As for the cooler itself, there’s not much difference between the performance of single and dual fan setup, so spending an extra $21.95 for another NF-A14 fan doesn’t seem like a good move for near 1-2 degree centigrade improvement. As for the build quality, I’m very happy with the quality of the product and the thermal and acoustic performance of the NH-C14S. The rubber padding on the fan helps out with the acoustic performance of the cooler as the fans are barely noticeable from 2-3 feets away, and in a concealed chassis, I’m sure you won’t even notice it spinning. As as far as clearance of PCIe and RAM slots are concerned, you’re good. You’ve got good enough space for the PCIe slot, but when it comes to the RAM clearance, if you have the fan installed in the middle of the cooler, the fan will make it a little difficult to install a medium-sized RAM. But if you’re using the cooler with the fan mounted on the top, then you’re good to even install RAMs with high-profile heatsinks.
Verdict du test: "With the Noctua NH-C14S, you’re getting a C-Type CPU Cooler, which puts your fan on display in the system in a unique way, has great thermal performance, is very silent and is priced about right." (Ahmed Kazim Ahmed Kazim, Dragon Blogger)

NH-C14S test

Esistono in commercio moltissimi dissipatori ad aria che fanno più o meno il loro dovere. Il Noctua NH-D15S però, è secondo me il miglior dissipatore ad aria per processori Intel e AMD che esistano sul mercato. Difficile trovare un dissipatore in commercio per appassionati o per utenti che vogliono il “Top” che riesca ad offrire qualità, prestazioni, silenziosità e facilità di montaggio. Tutte queste ottime caratteristiche e tutte le tecnologie utilizzate in un unico dissipatore, ne giustificano pienamente il prezzo. Questo dissipatore Noctua NH-D15S è abbastanza simile all’NH-D15, ma non è la stessa cosa. Ha una ventola in meno, è progettato meglio nel design per essere compatibile con tutti i moduli RAM ed è ancor più silenzioso.
Verdict du test: "Se volete il “Top” dei dispositivi di raffreddamento ad aria, il Noctua NH-D15S è proprio il dissipatore che stavate cercando." (TechUniverse.it)

NH-C14S test

In questa recensione sull’ottimo dissipatore Noctua NH-C14S abbiamo potuto vedere come sia estremamente silenzioso nel suo funzionamento e le sue incredibili prestazioni di raffreddamento. Noctua mi ha ancora una volta sbalordito con un altro prodotto di altissima qualità. Questa casa produttrice è ormai da anni un sinonimo di qualità e di prodotti ad altissime prestazioni. L’estetica e il design di questo dissipatore sono davvero particolari: La Noctua non ha mancato di curare tutti i particolari di questo dissipatore offrendo un prodotto praticamente perfetto. Del resto, come si sa, la Noctua è solita progettare i suoi dissipatori e le sue ventole accuratamente proponendole in commercio solo quando questi prodotti non saranno più che perfetti e non soddisferanno tutti i requisiti richiesti. Con il dissipatore NH-C14S, la Noctua offre un prodotto davvero eccezionale. Un dispositivo di raffreddamento che non ha davvero nulla da invidiare ad altri sistemi di raffreddamento per processori concorrenti. Non ha nulla da inviadiare nemmemo ai sistemi AIO di raffreddamento a liquido di altre case produttrici ben più costosi.
Verdict du test: "Un dissipatore per processori Intel e AMD praticamente perfetto in tutti i suoi aspetti; nell’installazione semplice, nei livelli di rumorosità estrememente bassi, nelle prestazioni di raffreddamento eccezionali, e, sopratutto, nell’ottimo rapporto tra qualità e prezzo in cui viene offerto in vendita. Che altro dire? Un prodotto eccezionale davvero molto consigliato." (TechUniverse.it)

NH-C14S test

While the performance of Noctua NH-C14S is not that impressive when compared to the NH-D15, let us remind you that the NH-C14S is a low-profile cooler made for HTPC or SFF PC builds. While it struggles to tame the Intel Core i7 5820K on LinX, actually the Noctua NH-C14S is still one of the best in its class. If you are in search of a good CPU cooler for your Intel LGA 115X or AMD AM4-based ITX or mATX rig, the Noctua NH-C14S offers great cooling in compact dimensions.
Verdict du test: "The Noctua NH-C14S caters to enthusiasts with space constraints yet desire the best air cooling they can get in their small rigs with its good performance and silent operation." (Muhammad Firdaus, Pokde.net)

NH-C14S test

The third cooler of our review, the Noctua NH-C14S, is virtually incomparable with the previous two coolers. It has over twice the mass of the other coolers and requires a much greater vertical clearance - at least 115 mm depending on configuration - instantly ruling it out as an option for the vast majority of HTPC cases and other narrow designs. If the fan were to be placed at the top of the cooler in order to increase the clearance of the RAM modules, it is unlikely that the NH-C14S will be compatible with any desktop or HTPC case, as it would not even fit inside designs that are meant for top-tier HTPCs. It is apparent that Noctua has designed the NH-C14S solely for users that are planning to build very high performance HTPC system with sizable cases and want a product that can compare to high performance tower coolers. Naturally, it cannot reach the performance of coolers such as the NH-D15 or the Cryorig R1 Ultimate, but it does get close enough to warrant excellent performance on any CPU currently available, overclocked or not.
Verdict du test: "It is an expensive cooler but the quality and performance are well worth the money." (E. Fylladitakis, Anandtech.com)

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)

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 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

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.

Open Socket

Can the cooler be installed turned by 90° on AMD sockets?

No. The new SecuFirm2™ mounting system for AM2, AM2+ and AM3 uses the same standardised hole spacing as the Intel system and thus allows for a much easier installation, but the cooler cannot be installed turned by 90°.

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.

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 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.

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).

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.

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.

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:

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 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 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.

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).

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.

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?

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.
