Award-winning NH-D15 cooler
Tens of thousands of enthusiast users all over the world swear by the NH-D15’s quality and performance. Recommended by more than 200 international hardware websites and magazines, it is renowned for being one of the best high-end coolers on the market.
|
chromax.black design
The NH-D15 chromax.black is black from head to toe: Featuring a black coated heatsink, black fans with black anti-vibration-pads, black fan clips and black mounting parts, it’s right at home in all-black builds and easy to integrate with other colour schemes.
|
6 heatpipe dual tower design
As compared to conventional single tower heatinks, the NH-D15's fine-tuned six heatpipe dual tower design provides more surface area, better heat-distribution and superior airflow efficiency in dual fan mode.
|
Widened fin stack and expanded heatpipe layout
Compared to the NH-D14, the NH-D15's fin-stack has been widened from 140 to 150mm and its heatpipes are now spaced further apart, which allows for a more uniform heat distribution over a larger surface area and thus contributes to the NH-D15's superior efficiency.
|
High RAM compatibility in single fan mode
Thanks to its recessed lower fins, the NH-D15 provides 64mm clearance for tall memory heatsinks in single fan mode, making it compatible with most high end RAM modules on the market. In dual fan mode, the NH-D15 should be used with standard height RAM (up to 32mm).*
|
Dual NF-A15 140mm fans |
SecuFirm2™ multi-socket mounting system
Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) and LGA20xx (LGA2066, LGA2011-0, LGA2011-3), as well as AMD AM4, AM3(+), AM2(+), FM2(+) and FM1, the SecuFirm2™ mounting included with the NH-U12S is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use.
|
Compatibility with past and future sockets
Thanks to Noctua’s SecuFirm™ ecosystem, the NH-D15 can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets, which makes the NH-D15 a safe long-term investment.
|
NT-H1 thermal compound
Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide, it has established itself as a benchmark for premium-quality thermal compounds.
|
Soldered interface between heatpipes and fins
With many heatsinks, the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance. By contrast, the NH-D15’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage.
|
*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.

NH-D15 chromax.black Review
El Noctua NH-D15 chromax.black sigue siendo sin lugar a dudas todo un referente en lo que a refrigeración por aire se refiere, aunque con mucha competencia en el mercado de la refrigeración liquida. Frente a ellas, tiene la ventaja de ser más duradero y no tener el riesgo de una posible fuga, pero a cambio de unas dimensiones que no son aptas para cualquier chasis.
|
|||||||
Test verdict: "Esta renovada versión en negro es una clara respuesta a todos esos usuarios que nunca han gustado del color clásico de la marca, pudiendo además decorar las puntas de los ventiladores con las gomas de colores que ofrece la marca. En cualquier caso, una alternativa más para todos los gustos." (Iván Martínez, El Chapuzas Informático)

NH-D15 chromax.black Review
Nous avons photographié chacun des trois modèles sous tous les angles, à la recherche de la moindre imperfection.
Nous avons fait “chou blanc”… Le noir envahit la totalité du ventirad, jusqu’aux petits circlips maintenant les vis montées sur ressort.
La finition est excellente et l’on n’en attendait pas moins de la part de Noctua.
Seule la base cuivrée du radiateur revêt son placage nickelé.
On constate que même les accessoires du système de fixation revêtent cette couleur.
Un noir d’aspect satiné habille donc trois ventirads, Noctua ayant sélectionné trois modèles représentatifs des différents formats.
Le NH-D15 chromax.black, vaisseau amiral de la flotte autrichienne, doté d’un radiateur au format double tour et accompagné de deux ventilateurs.
Le NH-U12S chromax.black qui représente le ventirad doté d’un radiateur au format simple tour et accompagné par un seul ventilateur.
Le NH-L9i qui représente le format Top Flow.
|
|||||||
Test verdict: "Vous aimez les performances des ventirads issus de la marque Noctua, mais… Mais, vous ne pouvez franchir le pas en raison des couleurs spécifiques à cette marque.
Cette époque est maintenant révolue !" (Bertrand Curras, modding.fr)

NH-D15 chromax.black Review
Besonder gefreut hat uns, dass die neue Optik ganz ohne Nachteile daherkommt. Die Temperaturen haben sich im vergleich zum Original nicht verändert und somit ist der NH-D15 chromax.black wieder ganz vorne in unserem Ranking.
Auch ist die Beschichtung offenbar sehr robust, denn trotz wiederholter Montage haben wir keine Kratzer an ihr entdecken können.
Die alten Noctuastärken bleiben auch beim chromax.black erhalten: Tolle Verarbeitung, ungemein laufruhige Lüfter, üppiger Lieferumfang und lange Garantiezeiten. Noctua kombiniert also nun Funktion mit Design zu einem ungemein tollen Produkt.

NH-D15 chromax.black Review
Ako vidíte z grafu, rozdiel medzi klasickou verziou a čiernou je minimálny a skôr je tento rozdiel spôsobený nepresným meraním okolitej teploty. Dá sa povedať, že výkon nových chladičov je identický.
|
|||||||
Test verdict: "Prvú vec, ktorú musím napísať je fakt, že chladiče vyzerajú naživo ešte lepšie ako na fotkách. Prvý dojem je veľmi pozitívny a kto má rád čierne edície chladičov, tak si príde na svoje. Čo sa týka výkonu nemusíte sa absolútne báť nejakého zhoršenia. Merania hovoria v prospech čiernych edícií, aj keď rozdiel vo výslednej teplote je tak malý, že ide o identický výkon a skôr pôjde o vaše preferencie čo sa týka farby a či ste ochotný priplatiť približne 10 eur navyše."

NH-D15 chromax.black Review
Noctua has released the all-black chromax edition of their award-winning CPU coolers i.e NH-L9i, NH-U12S, and NH-D15. Since Noctua is soldering the copper heat pipes with the fins, they were on the lookout for the coating material that will not impede the thermal performance over the longer period of time as well as the new production process for this coating. The chromax edition of these coolers is identical to the original coolers with one exception which is the all-black color. All-Black here refers to literally every component/accessory being in the black color be it the heatsink or the fans or the mounting hardware. These coolers from head-to-toe are black.
|
|||||||
Test verdict: "With just $10 above the user can get a cooler with the same footprint and a similar thermal performance but with better aesthetics and neutral color that can be used in any themed build." (Nauman Siddique, EnosTech.com)

NH-D15 chromax.black Review
A Noctua a chromax.black családjával hatalmasat lépett előre. Habár teljesítményben sokat nem sikerült fejlődniük, a küllemben mindenképp. Talán a jelenlegi AIO folyadékhűtés őrületet a háttérbe szoríthatja és újra előtérbe kerülhet a léghűtési megoldások élén a Noctua, hiszen számos csicsás, vagy minimalista konfigurációba is tökéletesen illeszkedik.
|
|||||||
Test verdict: "A halk működés és mindemellett gyönyörű kidolgozás abszolút a Noctua felé billentheti a mérleget, ha az ASSASSIN III és a Noctua közt kell döntést hoznunk. A dizájn gyönyörű lett, mégis letisztult, de a teljesítményen sokat nem sikerült javítani, így én egy Ajánlott plecsnivel díjaznám a terméket."

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.

Can I keep using the backplate / mounting system of my previous Noctua cooler for my new one?
My unlocked Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?
- the TDP limits are extended or disabled in the motherboards' BIOS.
- the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
- 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.
What Thermal Design Power (TDP) is this cooler recommended for and how much Watt (W) of heat can it dissipate?
Can I install a Noctua cooler in my system from Acer, Dell, HP or Lenovo?
Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often use motherboards which differ slightly from the specifications issued by Intel and AMD. While those changes are usually subtle, they can lead to compatibility issues with coolers that were built to comply with these specifications.
Even in case the cooler is mechanically compatible and can be installed, other issues can occur, e.g. proprietary fan connectors, BIOS errors due to a low fan speed, shutdowns, etc. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues can often not be resolved.
Due to the large number of possible issues that cannot be resolved with different mounting parts alone, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.
My case supports CPU coolers of up to XXXmm height, which model should I choose?
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 600 or 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 in the BIOS 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, by using 3rd party tools like IPMItool or IPMIutil, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply). Please note that any modifications performed with 3rd party tools are done at your own risk and that Noctua can not be held responsible for any possible issues.
I get a CPU fan error using my Noctua PWM fan, is it faulty?
Does the coating of the chromax.black coolers affect performance?
Why is my Ryzen 3000 processor getting so hot? Why are Ryzen 3000 CPUs running hotter than previous generation Ryzen CPUs with the same TDP rating? Is there anything wrong with my cooler?
The latest Ryzen 3000 processors (except APU models) differ from previous Ryzen generations in that they are no longer based on a single, large chip but use a multi-chip approach with smaller chips instead. Depending on the exact model there can be one (6 and 8-core models) or two (12 and 16-core models) actual CPU-Dies (CCD) on the package. Each processor also uses an I/O-Die (IOD), which contains things like the memory controller, PCIe controller, connections to the motherboard chipset and other functions.

Because of this design change and the switch to a smaller 7nm manufacturing process, the heat distribution of the overall processor is much different from older 14nm and 12nm based single-chip Ryzen processors with a similar power draw.
Depending on the exact CPU model, its specified TDP value and possibly extended power limits (precision boost overdrive), a single CPU-die can create a heatload of up to 130W easily, whereas the I/O-die usually creates a heatload of about 10W. Due to the small size of the CPU-die, the heat density (W/mm²) of this chip is very high. For example, a 120W heatload at a chip-size of 74mm² results in a heat-density of 1.62W/mm², whereas the same heatload on an older Ryzen processor with a chip-size of 212mm² gives a heat-density of just 0.57W/mm².
This large difference in heat-density is the reason why newer Ryzen 3000 processors become much warmer at similar heatloads than their predecessors.
Furthermore, Ryzen 3000 CPUs are using the rated temperature headroom (up to 95°C) quite aggressively in order to reach higher boost clocks. As a result, it is absolutely no problem and not alarming if the processor runs into this temperature limit. The clock speed and supply voltage will be adjusted automatically by the processor itself in order to remain within AMD’s specifications and to prevent overheating.
Due to the higher heat density, higher thermal limits and more aggressive boost clock usage, it is perfectly normal that Ryzen 3000 CPUs are reaching higher temperatures than previous generation Ryzen CPUs with the same TDP rating. Higher CPU temperatures are normal for Ryzen 3000 processors and not a sign of that there is anything wrong with the CPU cooler.
My Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?
Current processors from Intel, especially the unlocked models with the suffixes C, K, X or XE (e.g. Core i7-8700K, Core i9-7900X oder Core i9-9900K) can dissipate noticeably more heat than indicated by the TDP specification.
While many motherboard models stick to the recommended power levels and clock speeds settings from Intel, there are models where the UEFI BIOS is configured in such a way that:
- the TDP limits are extended or disabled.
- the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
Depending on the load scenario and CPU configuration settings, the actual power draw can be 1.5-3 times as high the stated TDP value. This can lead to temperature issues, especially when using smaller coolers, compact cases or cases with poor airflow, when some applications create very high loads, e.g. Prime95 with AVX2 support, 3D-rendering or simulation software.
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. You might also want to limit the TDP to either the specified value by Intel or a value that is 5-10W below the value previously read out from the CPU. This can be done in BIOS by setting the “Long Term Duration Power” manually instead of “Auto”.
Furthermore, 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.
The option to set an AVX-offset value is usually available for the following CPU generations:
- LGA1151:7th, 8th and 9th generation (Kaby Lake, Coffee Lake)
- LGA2011-3: 6th generation (Broadwell-E)
- LGA2066: 7th and 8th generation (Skylake-X)
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 most 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.
Please also note that CPUs that use thermal paste instead of soldering between the DIE and the heatspreader generally run hotter. Due to the thermal bottleneck created by the thermal paste, temperatures can be high even at the specified TDP.
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.

How to remove the base protection cover?
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:

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?
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).

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

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).
What’s the difference between NH-D15 and NH-D15S?
- Asymmetrical design: While both coolers are 150mm wide, the NH-D15S is off-set towards the top edge of the motherboard and thus provides more clearance towards the PCIe slot.
- RAM clearance: While the front fan of the NH-D15 overhangs the RAM slots on many motherboards, the single fan NH-D15S provides 65mm clearance for tall RAM modules on all compatible sockets.
- Total height: While the front fan of the NH-D15 must be installed slightly higher in order to provide sufficient clearance for standard height (32mm) RAM modules, the single center fan of the NH-D15S can be installed lower on the fin stack. As a result, the total height of the NH-D15 including fans is 165mm whereas the total height of the NH-D15S including its single center fan is only 160mm.
- Performance: While the base performance of the NH-D15 and NH-D15S heatsinks is identical, the dual fan configuration of the NH-D15 can provide 1-3°C better performance. Users who have sufficient room can also upgrade the NH-D15S with either a 120mm (e.g. NF-A12x25 PWM) or round 140mm (e.g. NF-A15 PWM) fan on the front fin stack in order to achieve the same performance levels as the NH-D15. The fan clips for installing a second fan are included with the NH-D15S.
