NH-D15 Review

Эффективность и качество — неоспоримые атрибуты Noctua NH — D15 и, прежде всего, этот обзор планировался для того, чтобы оценить эффективность кулера на примере актуальных и популярных процессоров. Как видно по итогам тестирования, Intel Core i7 -7700K и AMD Ryzen 7 1700 успешно охлаждаются данной системой охлаждения и даже есть запас под серьезный разгон, впрочем, мы и достигли практически максимальных частот для этих процессоров. Единственная платформа, с которой Noctua NH — D15 справляется с трудом — это LGA 2066 и, если эксплуатировать процессоры в стоке, то у вас все будет в порядке, но как только вы тронете разгон, его эффективности может не хватить, процессоры на архитектуре Skylake — X получились, и вправду, очень горячими.
Test verdict: "По итогам тестирования Noctua NH — D15 получает награду Выбор редакции. Это далеко не самая дешевая система охлаждения, но ее эффективность и качество не ставится под сомнение." (Ульяна Шельдяева, Najdiigru.ru)

NH-D15 Review

Noctua ha rizado el rizo con esta nueva versión de su disipador estrella, el Noctua NH-D15, a pesar de su precio algo alto para lo que estamos acostumbrados en ventilación (90€+/-), se trata de un producto de la máxima calidad con el que no es fácil rivalizar en resultados, si a esto añadimos la pasta térmica incluida que se encuentra entre las mejores, los resultados como comentábamos anteriormente han sido mas que excelentes. Uno de los grandes añadidos de hacerse con un producto de Noctua es el hecho de que si sale un nuevo Socket no compatible o si hemos perdido alguna de las piezas del anclaje o ventiladores podemos ponernos en contacto con el fabricante para que nos las envié sin coste ninguno, lo cual es un plus que ofrecerá una vida muy larga a nuestro disipador.
Test verdict: "En conclusión como decía al principio del análisis estamos probablemente ante el mejor disipador por aire del mercado que incluso llega a rivalizar en prestaciones contra algunas de las refrigeraciones liquidas AIO mas convencionales, así que le otorgamos el galardon OCKD Platino, ya que difícilmente sera un producto que se pueda superar y las contras se han reducido bastante con esta nueva versión."

NH-D15 Review

O Noctua NH-D15 cumpre integralmente com todas as expectativas. A começar logo pela embalagem, com a sua irrepreensível protecção e cuidado na apresentação, passando pela muito elevada qualidade de construção e de materiais, tanto do dissipador como das ventoinhas e terminando no desempenho. Aqui a palavra de ordem é “silêncio”. O NH-D15 é indubitavelmente muito eficiente a remover calor do CPU, mas é o silêncio com que o faz que realmente impressiona. E é neste ponto em que se torna difícil encontra concorrência à altura. Não é todos os dias que encontramos um cooler capaz de manter as temperaturas de um CPU de 8 núcleos de alto desempenho com overclock perfeitamente controladas, sem que ninguém dê conta que um sistema se encontra em actividade na divisão. A julgar por este modelo, a reputação da Noctua neste campo é inteiramente merecida.
Test verdict: "[Q]uem procura um cooler com uma combinação ímpar de silêncio e desempenho tem aqui uma excelente opção. Talvez, mesmo a melhor. Recomendado." (António Pinto, ZWAME.pt)

NH-D15 Review

Nincs egyszerű dolgunk a Noctua NH-D15 értékésével: ha csak a teljesítményét vesszük figyelembe, akkor egyértelmű lenne a különösen ajánlott cím, hiszen hűtési képességekben, zajszintben és szerelhetőségben is ott van a legjobbak között. Csak éppen ott van az ár, ami 30-35 ezer forint körül mozog, ez pedig már tényleg a csúcs, ami a „közönséges” ventilátoros hűtéseket illeti.
Test verdict: "Óriási teljesítmény, csendes működés és remek szerelhetőség, de magas ár és megosztó dizájn jellemzi a Noctua új csúcsmodelljét." (Gabor Rosta, Prohardver.hu)

NH-D15 Review

Noctua NH-D15 zdecydowanie zasługuje na miano produktu klasy premium. Wydajność na poziomie zamkniętych układów chłodzenia cieczą typu AiO, nienaganna kultura pracy oraz wyjątkowo łatwy i przyjazny montaż połączony ze świetną kompatybilnością daje nam cooler wręcz nieprzeciętny. Wyniki pomiarów temperatury pod obciążeniem pokazują, że NH-D15 jest w naszej platformie testowej lepszy od konkurencji, jednakże ze względu na specyfikę tego układu, niewielka różnica temperatur w naszych testach zacznie nabierać dużego znaczenia przy procesorach o większej ilości rdzeni i wątków, konstrukcjach bardziej rozbudowanych, gdzie wydzielane będzie jeszcze więcej ciepła. Największym atutem NH-D15 jest możliwość konkurowania z chłodzeniami All-in-One, które nierzadko są jeszcze droższe niż testowany w tym tekście cooler. Bywają także bardziej awaryjne i nierzadko głośniejsze, gdy weźmiemy pod uwagę hałas generowany nie tylko przez wentylatory, ale pompkoblok obsługujący tego typu układy. Chłodzenie austriackiej firmy może nie odpowiadać niektórym estetykom, ale jego pozostałe aspekty plasują go jako najlepsze chłodzenie procesora, z jakim miałem kiedykolwiek do czynienia. I mam przeczucie, że prędko się to nie zmieni.
Test verdict: "Jeśli planujecie skutecznie schłodzić mocno podkręcone procesory, takie jak mainstreamowe i5-7600k, i7-7700k czy bardziej rozbudowane konstrukcje na platformach LGA-2011v3, ale nie ufacie układom AiO, to Noctua NH-D15 może być dla takiego zestawu idealna. Będziecie jedynie musieli przywyknąć, aby nie zaglądać co chwilę do obudowy, by sprawdzić, czy wentylatory faktycznie pracują. GamesGuru zdecydowanie poleca ten cooler każdemu, kto nie zwykł iść na kompromisy, jeśli chodzi o sprzęt komputerowy." (Filip Ciemiński, GamesGuru.org)

NH-D15 Review

Comparing the results between the Cooler Master MasterAir 4 and Raijintek Triton, the Noctua NH-D15 sit between these two coolers. The real differences between Noctua NH-D15 and these two coolers are the acoustic levels. Noctua NH-D15 fan are surprisingly quiet. I was truly impressed as I could barely hear the fans even during the stress tests. Meanwhile, the MasterAir Pro 4 and Raijintek were rather noisy as the fans ran full tilt to keep the temperature down.
Test verdict: "Noctua's NH-D15 is still the top air cooler despite being launched back in 2014, even besting some AIO liquid cooling solutions available in the market now." (Muhammad Firdaus, Pokde.net)

NH-D15 Review

Noctua con questo dissipatore ha fatto un capolavoro. Il corpo di questo dispositivo di raffreddamento non presenta imperfezioni o sbavature. Ovviamente, esistono sistemi di raffreddamento a liquido che hanno performance migliori di raffreddamento ma si tratta comunque di dispositivi con una pompa, liquido e radiatore. Chi come me, preferisce un dispositivo di raffreddamento con semplici ventole e corpo con alette in alluminio, questo Noctua NH-D15 è davvero la scelta migliore. Se a qualcuno non piace il colore delle ventole, nessuno gli impedisce di poterle cambiare con altre magari colorate o con illuminazione a LED. In realtà, il montaggio di questo dissipatore è piuttosto semplice. Le uniche cose di cui ci dobbiamo preoccupare è l’altezza dei moduli delle memorie RAM, ma è un problema facilmente risolvibile alzando la seconda ventola o in caso estremo, non mettendola proprio. Grazie alle clip, è facile collegare le ventole al corpo del dissipatore. Nella scatola, la ventola centrale è già installa al centro del dissipatore ma è necessario rimuoverla prima dell’installazione altrimenti non possiamo arrivare a stringere le viti di fissaggio. Il Noctua NH-D15 è un dissipatore ad aria ideato sopratutto per i processori che scaldano parecchio o con overclock piuttosto spinto.
Test verdict: "Se cercate il miglior dissipatore ad aria ad alte prestazioni di raffreddamento per il vostro processore Intel o AMD, il Noctua NH-D15 è davvero molto consigliato." (TechUniverse.it)

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).

Yes, fan clips for installing square frame 140mm fans (such as the NF-A14) are available on request via our customer support.

How big is the NH-D15 and how much clearance does it provide for RAM and chipset coolers?

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

D15

The front fins of the NH-D15 generally protrude over the RAM slots. Due to the recessed lower fins, it is still possible to use RAM modules with up to 64mm height in single fan mode. In dual fan mode, the front fan will sit above the RAM slots as well. In this case, Noctua recommends using standard height RAM (up to 32mm). However, in chassis with more than 165mm CPU cooler clearance, the front fan can be moved upwards to make room for memory modules taller than 32mm (e.g. moving the fan 5mm up will increase the total height from 165 to 170mm and make room for 37mm tall modules).

Can I install a third fan on the NH-D15?

Adding a third fan to the NH-D15 only yields minimal improvements in cooling performance (0.5°C max.), but noise levels will increase significantly. As this doesn’t make sense from a technical point of view, we don’t include mounting hardware for a third fan in the box and don’t offer it separately.

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).

The supplied y-cable is missing a wire at one of the two connectors, is it faulty?

No. As mainboards can process only one rpm-signal per fan header, it would cause problems if the cable transmitted rpm-signals of both fans. For this reason, one of the two connectors does not have an rpm wire and only the fan on the other connector will transmit an rpm signal. Automatic speed control of both fans will work independently from the second fan’s rpm signal.

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.

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

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.

amd backplate

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

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.

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.

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.

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.

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.

Why doesn't the base of Noctua coolers have a polished, mirror like finish?

As most of today's PC enthusiasts use high-viscosity thermal compounds, the contact surface of Noctua coolers is optimised for use with this type of pastes. The micro-grooves at the contact surface ensure that high-viscosity thermal compounds are dispersed to a uniform thin layer across the whole contact area and that no air pockets remain between the cooler and the CPU. With a polished, mirror like surface, the risk of uneven dispersion is much higher. As too thick layers of thermal paste and air pockets drastically deteriorate heat transmission, the micro-grooves are is of vital importance to the overall cooling performance of Noctua coolers when used with today's high-viscosity thermal pastes.

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

Please refer to our socket compatibility chart.

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).

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.

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.

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.

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

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.

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.

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.

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.
