NH-D14 Opinión

Now on to the reason why we are here, the Noctua. Even with the fans running at 12v immediately this cooler stands out from the crowd, or rather hides in the shadows, as it is so quiet I even checked to see if the centre fan was actually running. With the fans at 12v the hottest core on the CPU never went above 68 degrees. Yeah that’s right it never even got to 70 degrees! Something that was also very apparent was the sheer amount of heat pouring out the back of the heat sink, just placing your hand near the back of it you could feel the warm air, nothing unusual but the temperature and the amount of air being forced out the back at such an inaudible rate was a massive shock to me. So stage one went very well, but for some reason I didn’t hold out much hope for the fans being run at silent, especially not with our 4ghz over clock… right? Well put your cup of tea down, swallow that mouthful of sandwich because you about to spit it out or choke in shock. With the fans on low, which I might add is about as close to silent as you will ever get with 2x 140mm fans pushing over a heatsink, the CPU’s hottest core never went above 72c! A 4ghz overclock on an i7 920 on air, with silent fans at 72c! Not quite believing this I left the sytem running on the final test for the whole day, a total of 6 hours in the end running at 100% and still even after that it never went above 73c!
Resultado del análisis: "I’m so amazed by this coolers low noise yet class leading performance I will not only recommend it and award it with our coveted gold ‘Best in Class’ award but most importantly for a reviewer I am actually going to continue using it in my own personal rig which is worth more than any award in the real world!"

Noctua NH-D14 13.03.10 Noctua NH-D14 5 Componente: Dissipador para CPU Plataforma: Intel/AMD Fabricante: Noctua Cedido por: Noctua Família: Refrigeração Data de Lançamento: 09 Novembro 2009 Preço: 70€ Conclusão Parece que chegamos à página final, queria deixar desde já um agradecimento à Noctua por nos ter feito chegar mais um dos seus dissipadores para review! O Noctua NH-D14 é um dissipador grande, pesado, robusto e completamente artilhado com ventoinhas de topo e um sistema de fixação excelente. Inicialmente podia pensar-se que por ter estas dimensões a instalação seria um bicho-de-sete-cabeças, como aconteceu no IFX-14 ou no Orochi mas com o Secure Firm 2, foi canja! Se conseguirem mete-lo na vossa caixa e se a vossa carteira aguentar, este dissipador é o investimento a fazer! No entanto, o preço recomendado pode fazer alguns clientes mudarem de ideias antes de finalizar a compra, ainda está na casa dos 70€ e com a especulação sobre a Euribor já estamos todos a poupar! A combinação da NF-P12 com a NF-P14 é o casamento perfeito para ter o melhor desempenho com o mínimo de ruído. Do valor que falei em cima cerca de metade corresponde ao preço de mercado destas duas ventoinhas. Nos testes o NH-D14 destacou-se, aguentando na perfeição todos os processadores testados mesmo com OC e altas voltagens!

NH-D14 Opinión

Turning up the heat a little with the system overclocked to 3.5GHz, the NH-D14 is really starting to shine beating the Cooler Master V10 by 2.25 degrees, and it is a massive 21.25 degrees ahead of the stock Intel cooler.
Resultado del análisis: "With the Noctua NH-D14 beating out 18 other coolers on our overclocked Intel Core i7 920 processor we have to give it the Legit Reviews Editor's Choice award! [...] Noctua did what they set out to do: made a new cooler that performed better and was just as quiet. If you can shoe horn it in your case, it's well worth the money."

NH-D14 Opinión

What I was able to achieve with the NH-D14 was prime stability at 4.2GHz with load temperatures that peaked at 70 degrees Celsius and ran most of the time in the mid to high 60's. I was not prepared for this result, but am now thoroughly impressed with the performance of the NH-D14. All that, with no noise. Absolutely sick! I went into the testing knowing that the performance of the NH-D14 was going to be good. I just did not realize how good. When I ran it through the testing, it was far and above superior to the comparison heatsinks. Of course, there is no reason for it not to be, simply based on the size and construction of the NH-D14. The surface area available to remove the heat is huge. It easily looks like the dual-fin arrays each encompass as much or more surface area than the previous top dog in Noctua's arsenal, the NH-U12P SE 1366. Add in an additional two heatpipes and you have a winning recipe. With load temperatures in the high 40's Celsius (49°C to be exact) when overclocked to 3.3GHz, I figured I would take a shot at some big numbers with an overclock up to 4.2GHz. My DO stepping 920 is not a bad clocker and could previously do 4.2GHz on air, but the temperatures would keep the processor just stable enough to only run this speed for short benchmark runs and did not offer any kind of stability. Something I needy when running a distributed computing project. Enter the Noctua NH-D14. I cranked up the bclock to 210 with a 20 multiplier for an even 4.2GHz, adjusted the vcore to 1.375v in the BIOS and crossed my fingers. Of course, hyperthreading is on. Temperatures at 4.2GHz with any of the other heatsinks in my possession would start pushing 80°C+ at this speed. Not so with the NH-D14. The highest temperature I saw was 71°C on two of the four cores, with the heatsink for the most part keeping the temperatures in the 65°C to 68°C range. Pretty spectacular results from this heatsink. It delivered results that averaged four degrees Celsius better under load both at stock and overclocked speeds. Four degrees Celsius does not seem like a big drop in temperatures, but it is when you are comparing top of the line heatsinks.
Resultado del análisis: "All things considered, this is the best heatsink I have ever tested. You get a massive dual-tower, six-heatpipe design that incorporates both a 120mm and 140mm fan to deliver outstanding results that show larger gains as the thermal load increases. All that without the noise associated with high end air cooling. Hey, size really does matter, and yes, you can pay for performance!" (Frank Dimmick, OverclockersClub.com)

I was really surprised that the Noctua could keep such a low ambient temperature, but I ran the test three times and reapplied TIM every time looking for what I did wrong, but I couldn’t find anything odd. As for the load temperatures, all I can say is I have a huge smile on my face still.

NH-D14 Opinión

Here we should dwell on several interesting things. Firstly, Noctua NH-D14 is currently the only solution that can cool a CPU overclocked to 4 GHz running Linpack 64-bit with two fans at 600 RPM. Believe me, it is an unprecedented achievement! [...] As you see, the new Noctua flagship solution is one step ahead of Thermalright IFX-14 in all test modes. In quiet mode with one 140 mm fan NH-D14 is 3°C more efficient than the competitor, and in almost all other cases – 2°C more efficient. [...] I will be brief about the acoustic performance of Noctua NH-D14: up to 1000 RPM the cooler was extremely quiet and at maximum rotation speed the noise was moderate.
Resultado del análisis: "No doubt, Noctua NH-D14 is an excellent cooler starting with secure packaging and highly informative official web-site and ending with superb manufacture quality, highest performance and low noise levels. Obviously Noctua engineers paid attention to every single detail, every little trifle, which paid back big: their true work of art became the indisputably best cooling solution out there. That is why we are proud to award it with our Editor's Choice title as the best CPU air-cooler in the today's market." (Sergey Lepilov, X-bit labs)

NH-D14 Opinión

Selten verbauen Hersteller serienmäßig zwei unterschiedliche Lüftermodelle in gar zwei unterschiedlichen Formaten. Noctua hat diesen Schritt beim NH-D14 gewählt, um Kompatibilitätsproblemen aus dem Weg zu gehen, zum Teil aber dennoch den Vorteil der großvolumigen Belüftung zu genießen. Qualitativ hinterlassen beide Exemplare einen hervorragenden Eindruck. Die Lüfter wirken ungemein robust und exakt verarbeitet, Ungenauigkeiten und ein Spiel des Rotors sucht man vergebens. So verwundert es grundlegend auch nicht, dass beide Modelle über ihr gesamtes Drehzahlspektrum hinweg (NF-P12 von 400 bis 1300 U/min, NF-P14 von 400 bis 1200 U/min) praktisch ohne schleifende, klackernde oder ratternde Nebengeräusche auskommen. Selbst das Antriebsgeräusch des Rotors wird im Allgemeinen vom Luftumschlag verdeckt. [...] Serienbelüftet setzt der NH-D14 in Referenz zur angelgten Drehzahl die Messlatte ein ordentliches Stück nach oben. Sowohl im Einzellüftermodus mit zentralem NF-P14 als auch im Doppellüfter-Betrieb mit beiden mitgelieferten Ventilatoren wird die Konkurrenz zum Teil deutlich abgehängt.
Resultado del análisis: "Mit dem NH-D14 katapultiert sich Noctua in imposanter Art und Weise an die Spitze aktueller Komplettkühlervergleiche. Dies geschieht mit einem gewohnt sehr gut abgestimmten Gesamtpaket aus Kühlkörper, Serienbelüftung, Montagesystem und Zugaben. [...] Insgesamt erhält man mit dem Noctua NH-D14 den wohl derzeit leistungsstärksten Prozessorkühler auf Luftbasis, der insbesondere bei niedrigen Drehzahlen und schwierigen Bedingungen seine Stärken ausspielt. Kombiniert wird die potente Doppeltower-Basis mit zwei sehr guten und bei Bedarf angenehm leisen Noctua-Lüftern sowie einer Spritze hochwertiger Wärmeleitpaste." (Martin Eckardt, Computerbase.de)

NH-D14 Opinión

When you see results showing new coolers outperforming previous crown holders by more than 4 degrees, impressive just doesn't cut it! The Noctua NH-D14, with and without the y-splitter is an outstanding 9.25 degrees better than the NH-U12P and is clearly in a different league to the Thermolab Baram and Tuniq Tower. Noctua have managed to create the ultimate cooler through a very efficient and well though design rather than relying on the brute force of a high RPM fan. The U.L.N.A is further proof of that, managing to stay ahead of the competition even with both fan spinning at a mere 900 RPM. At idle, where normally we see very little variation, Noctua disproves the convention and sets the benchmark once again. [...] It wouldn't be Noctua if it wasn't silent so there's really not much to say here apart that the fans are virtually inaudible. The Ultra Low Noise mode further quietens an already silent solution whilst maintaining similar cooling performance. The phrase "to have one's cake and eat it too" justifies what Noctua stand for, silence and performance.
Resultado del análisis: "Today we see why Noctua have their name engraved at the very top and in the heart of the enthusiasts. Delivering unparalleled performance, it is unmatched in its cooling performance leaving others in its trail of dust, especially on an overclocked system." (Sahil Mannick, Vortez.co.uk)

Is the high weight dangerous for the CPU or socket?

No. Los disipadores Noctua poseen un sistema de montaje SecuFirm™ extremadamente fiable. Gracias a la conexión mediante tornillos al backplate de la parte posterior de la placa, el exceso de peso -según las recomendaciones de Inter y AMD- común entre los disipadores de gama alta, no tiene objeción posible.

¿Puedo refrigerar mi CPU sin ventilador (de forma pasiva) usando los disipadores Noctua?

Los refrigeradores Noctua no se diseñaron originalmente para su uso pasivo, aunque su capacidad de refrigeración es suficiente en muchos casos. Desafortunadamente, nos es imposible indicar que CPU concreta puede o no puede refrigerarse sin ventilador, pues depende de varios factores, como la temperatura de la caja, la ventilación o la orientación del socket. Generalmente, recomendamos usar un ventilador en primera instancia, y luego ir bajando las revoluciones de forma constante sin dejar de monitorizar la temperatura.

Can I use Noctua fans on my fan controller?

Our fans are compatible with the vast majority of fan controllers on the market. However, there is a compatibility issue with a few models such as the Zalman ZM-MFC2 and Bitfenix Recon, which apply Pulse Width Modulation (PWM) on the 12V line and use an unfavourable PWM carrier frequency. This can create an oscillation when used with certain fans, which will result in the fan speeding up and down. We therefore recommend not using the Zalman ZM-MFC2 or Bitfenix Recon with our fans.

My fan doesn’t spin when I start up the PC - is it faulty?

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your mainboard, it's possible that the mainboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors, deactivate your mainboard's automatic fan controller in the BIOS or connect the fan directly to the power supply using the supplied 3:4-pin adaptor.

Can I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?

You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.

PWM PWM

Is the cooler compatible with LGA1366 mainboards for Xeon 5500?

Due to the custom NM-I3 backplate, the cooler can not be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). Please choose our NH-U12DX 1366 for these mainboards.

1366 compatibility

My mainboard has more than one set of mounting holes. Which one should I use?

Please always use the standard set of mounting holes that's compliant with your socket type (e.g. 75mm LGA1156 hole spacing on LGA1156 sockets) and parallel to the sides of the socket. Don't use mounting holes which are rotated in relation to the socket.

1366 compatibility

How much clearance for RAM or chipset coolers does the NH-D14 provide?

The NH-D14 provides 44mm clearance for near-socket components:

Vibration Compensators Installation

Can I use Corair Dominator RAM with the NH-D14?

The NH-D14 is a large cooler that extends over the RAM slots on most mainboards. While DDR2 Corsair Dominator don't fit underneath the cooler, DDR3 Corsair Dominator do fit when the removable top heatsink is taken off as shown below. Please also note that the NF-P12 fan can be moved upwards or taken off in order to improve RAM compatibility as shown here.

DDR3

Can I install 3 fans?

The cooler doesn’t include mounting hardware for a third fan as most setups will have a chassis fan right behind the cooler. In this case, adding a third fan to the heatsink doesn’t offer a measurable performance benefit and can lead to acoustic disadvantages.

Can I install 38mm depth fans?

As the distance between the two radiators is only about 28mm, you can’t install fans with more than 25mm depth. It’s possible to install such fans on the front side of the cooler though.

The fan doesn’t start with the Ultra-Low-Noise Adaptor (ULNA)!

Unfortunately, many Gigabyte mainboards use a special control circuit that can lead to start-up problems in conjunction with the Ultra-Low-Noise Adaptor (ULNA). This control circuit remains active even when automatic fan control is disabled in the BIOS. In these cases, please use the fan without the ULNA or connect it directly to the power supply (or an external fan controller) in order to ensure reliable operation with the ULNA.

Is the mounting system compatible with LGA1155?

Yes. LGA1155 uses the same hole spacing as LGA1156, so the same SecuFirm2™ mounting system can be used.

Is the cooler compatible with AMD AM3+ and FM1?

As the hole spacing for CPU cooler installation on AM3+ and FM1 is the same as on AM2, AM2+ and AM3, the cooler is fully compatible with AM3+ and FM1 out of the box and doesn’t require any modifications or upgrades.

Is the cooler compatible with the Intel LGA2011 socket and Asus X-socket™?

The cooler doesn’t come with LGA2011 mounting hardware out of the box, but it can be upgraded to support LGA2011 via the NM-I2011 mounting kit.

Please also note that the cooler is fully compatible with Asus Rampage IV series LGA2011 motherboards that feature Asus X-socket™. Asus X-socket™ models use an interchangeable backplate that makes it possible to install LGA1366 heatsinks, so the cooler is fully compatible with these mainboards out of the box and does not require any upgrades to be installed.

Asus X-socket

In order to install the cooler on Asus X-socket™ mainboards, please first remove the mainboard’s LGA2011 backplate and install the LGA1366 backplate supplied with the mainboard instead (see the mainboard manual for detailed instructions). Then install the Noctua cooler as described in the supplied installation manual for LGA1366. In case you’ve lost the printed installation manual, you can download it here.

Can use the NF-A15 fan on my Noctua CPU cooler?

The NF-A15 is fully compatible with the NH-U12P, NH-C12P and NH-C12P SE14. On the NH-D14 and NH-C14, the NF-A15 fan can only be installed using optional fan clips. For this, please contact our customer service.

Can I install a 140mm fan with a square frame (e.g. NF-A14)?

No. Square 140mm fans like the NF-A14 would cause compatibility issues in many configurations and use a hole spacing of 124.5mm. The cooler's fan clips are designed for 105mm hole spacing as used by round 140/150mm and square 120mm fans.

The cooler's fans always run at full speed and can not be controlled by my motherboard, what's the problem?

Older, discontinued models such as the NH-D14, NH-C14, NH-U12P SE2 and NH-U9B SE2 ship with 3-pin fans that can only be controlled by means of voltage adjustment. When these models were introduced in 2009 and 2010, many motherboards supported this type of speed control, whereas today, most motherboards can only control 4-pin fans by means of PWM (Pulse Width Modulation). As indicated on the resepective product pages, these models have been discontinued and superseeded by newer models such as the NH-D15, NH-C14S, NH-U12S and NH-U9S, which, like all current Noctua CPU coolers, support speed control via PWM. If you would like to use PWM speed control, please purchase one of our current cooler models or change the fans for some of our 4-pin PWM fans. Alternatively, you can also use the supplied Low-Noise and Ultra-Low-Noise adaptors in order to reduce the speed of the supplied fans.

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.
