NH-U12P test

Alles in allem muss man Noctua zugestehen, eine der am besten abgestimmten und komplettesten Kühlerofferten des Marktes anzubieten. Kühlkörper, Lüfter, Wärmeleitpaste und Zubehör sind keine abgespeckten Bundle-Versionen, sondern das Beste, was Noctua zur Zeit zu bieten hat. Der Kunde erhält also keine Mogelpackung, sondern eine Premium-Combo, deren üppig anmutender Verkaufspreis von über 50 Euro unter diesen Gesichtspunkten als durchaus fair angesehen werden darf.
Verdict du test: "Noctua bereichert den Markt mit dem NH-U12P um eine Kühlercombo höchster Güte. In allen wichtigen Belangen, vom Lieferauftritt bis hin zur Performance, weiß Österreichs Aushängeschild in Sachen Prozessorkühlung ordentlich zu punkten. So finden wir im gesamten Drehzahlspektrum eine Kühlleistung auf dem Niveau der Spitzenkühler vor, die der hochwertigen Towerkonstruktion inklusive des Heatpipe-Quartettes beste Funktionalität bescheinigt."

NH-U12P test

In the NH-U12P’s dual fan configuration it was clearly the winner with a 1.75*C gap between it and the closest competitor, the Monsoon III LT. The NH-U12P SE1366 cooled our i7-920 to a very nice 56.25*C under full load, and a whopping 17.75* under stock. [...] With the system overclocked to 3.5GHz and under full load the stock cooler starts to scream for mercy as the load temp climbed to 83.5*C. The Vigor Monsoon III LT dropped back 2 spots, and the NH-U12P is still in the lead, keeping our i7-920 to a toasty 67.5*C; a whole 16* cooler then stock. [...] the Noctua NH-U12P CPU Cooler is the winner in our testing. Either in its original single fan configuration or in its new SE1366 dual fan configuration it led the pack and did it quietly.
Verdict du test: "The Intel Core i7 CPUs can get very toasty so the need of a quality cooler is a must. The Noctua NH-U12P is just that and will continue to be our King of Cooling." (Shane Higgins, LegitReviews.com)

NH-U12P test

Compared to the other air coolers, the $55 Noctua NH-U12P is a brilliant behemoth. Not only did it produce lower noise levels than the rest, it did so without sacrificing overclocking performance. Most importantly, the Noctua kept our overclocked Phenom's load temperature more than four degrees lower than the best our water cooler could manage.
Verdict du test: "When you factor in the cooler's smart design, excellent craftsmanship, and impressively silent fan, Noctua's price premium looks well justified. This cooler is perfect for those who want excellent cooling performance without having to give up quiet computing." (Joshua Buss, The Tech Report)

NH-U12P test

Noctua really has produced a top-performing cooler with incredibly low noise in the NH-U12P. The combination of staggered Vortex Control notches, SC Drive, and SSO bearings in a nine-blade design does the trick as promised. Paired with the venerable and continually refined Noctua heatsink, performance of the stock Noctua NH-U12P mirrors the top Thermalright all the way to 3.91GHz. Noise remains below our system noise floor throughout the entire range of testing. The Thermalright goes on to 3.94GHz with a single fan, indicating the design may be slightly more efficient. However, add a second NF-P12 to the Noctua and it also reaches 3.94GHZ and sets new records for cooling temperatures along the way. Even with two fans, noise remains below the noise floor - and you can reduce it even further with shunts if you choose. We saw no reason to do this as two fans at full speed were still as silent as we could measure in our system - with noise levels below a quiet suburban bedroom at night.
Verdict du test: "There is no doubt the Noctua NH-U12P has joined the ranks of the best performing coolers ever tested at AnandTech. With two NF-12P fans in push-pull, it turns in the best cooling results at the highest overclocks we have ever seen." (Wesley Fink, AnandTech.com)

Le Noctua NH-U12P est une magnifique révision du NH-U12F. Noctua a corrigé tous les points négatifs de sa première version, avec un ventilateur enfin adapté au refroidissement de radiateurs, une pâte thermique de qualité, une troisième vitesse de rotation disponible, et cerise sur le gâteau un radiateur également amélioré.
Verdict du test: "Le Noctua NH-U12P est une réussite totale. Un excellent radiateur, surmonté d'un non moins excellent ventilateur, avec un bundle de qualité contenant des modules de régulation de vitesse et une pâte thermique à la hauteur de nos espérances." (David Sergent, Puissance-PC.net)

NH-U12P test

Here again the Noctua NH-U12P did extremely well, beating the other coolers at idle by 5°C, 4°C factoring in the change in room temperature. At load the three top performers closed in a bit, but the Noctua was still a 1°C ahead (again factoring in the 0.9°C temperature difference). That's pretty darn good results from Noctua. [...] As we have seen previously, the NF-P12 fans are pretty damn amazing and in a heatsink-fan situation this is no different. Not only does the fan produce a very good amount of airflow, it also is incredibly quiet, even when ramped up to it's top speed. On putting on one of the voltage fan extension cables provided, you quite simply could not hear any noise from the cooler.
Verdict du test: "The Noctua NH-U12P performs very well, even against some of the top-rated heatsinks on the market. When I pulled the cooler out of the box I was initially impressed with build quality and then once it was in use I was highly impressed with it's cooling ability, as well as the performance of the excellent NF-P12 fans. Add in the fact that Noctua include some top-end thermal paste and we're onto a winner. " (Matthew Kemp, Overclock3D.net)

NH-U12P test

Noctua has worked their magic with a tower-design processor heatsink yet again. It is amazing to see just how far Noctua have pushed it. This newest incarnation beats its predecessor by a few degrees, and offers better compatibility thanks to its better motherboard component clearance. As with many heatsinks, it comes down to the fan used, and thankfully Noctua does not disappoint here. Bundling its kit with the premiere NF-P12 fan shows off what this heat sink can do even while being nearly silent.
Verdict du test: "The Noctua NH-U12P is a solid cooler that performs with the very best out there. Combine this with a strong fan that can be classified as 'silent,' and you have a complete package. For anyone in the market for a new processor cooler or if you are just looking to quiet your system down, this is one heat sink and fan combination that should be on your short list."

Vibration Compensators Installation

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.

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.

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 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.

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 CPU compatibility list for information on maximum recommended TDP and heat dissipation.

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

Systems from Acer, 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?

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.

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.

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.

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.

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 cooler compatible with socket AM2+ and AM3?

Yes. As AM2, AM2+ and AM3 are mechanically identical, the cooler is compatible with all three sockets.

Puis-je monter aussi des ventilateurs d'une hauteur supérieure à 25 mm ?

Oui. Les agrafes de montage des refroidisseurs NH-U s'engrènent dans les trous de passage des vis à la face inférieure du cadre du ventilateur et fonctionnent pour cette raison pour les ventilateurs de toutes les hauteurs. Des problèmes de montage ne peuvent être causés que par d'autres éléments dans le boîtier en cas d'utilisation de ventilateurs présentant des formes de cadre spéciales, pour lesquels les agrafes ne peuvent pas s'engrener dans les trous de passage des vis à la face inférieure.

Puis-je monter deux ventilateurs à la fois ?

Oui. Grâce aux 4 agrafes de montage, contenues dans la livraison, sur le NH-U12(F/P), deux ventilateurs de 120 mm peuvent être montés et, sur le NH-U9(F/B), deux ventilateurs de 92 mm peuvent être montés.

Le ventilateur doit-il être monté de manière à ce qu'il aspire du refroidisseur ou souffle vers le refroidisseur ?

Veuillez monter le ventilateur de manière à ce qu'il souffle vers le refroidisseur.

NH-U Airflow

Si vous voulez utiliser deux ventilateurs, veuillez monter l'un de manière à ce qu'il aspire et l'autre de manière à ce qu'il souffle.

De quel côté du refroidisseur le ventilateur doit-il être monté ?

Veuillez monter le ventilateur de manière à ce que l'air chaud puisse être évacué vers l'extérieur le mieux soit à travers le ventilateur de boîtier arrière (option de courant d'air 1) ou à travers le bloc secteur (option de courant d'air 2).

Est il possible de refroidir mon CPU sans ventilateur (passif)?

Radiateurs Noctua n’sont pas conçus à l’origine pour des opérations passives quoique la performance du refroidisseur soit suffisante dans beaucoup de cas. Malheureusement, il nous est impossible de vous indiquer quelles sont les CPU qui peuvent ou qui ne peuvent pas être refroidir sans ventilateur, car il dépend de nombreux facteurs comme la température, la ventilation ou orientation du socket. Généralement, nous recommandons, dans un premier temps, utiliser le ventilateur et de diminuer progressivement RPM en surveillant constamment la température.

How to install the fan using the supplied steel clips?

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.

I can’t spread the thermal compound by turning the cooler as described in the manual!

Due to the new LGA mounting bars with screw threads that facilitate the installation process, there's little room to turn the cooler as described in step 4 of the supplied manual. There's nothing to worry about though, as you can still turn the cooler by a few millimetres in order to help the thermal compound spread. We've also made the compound slightly less viscous so that the contact pressure of mounting system is wholly sufficient to spread it.

How can I connect 2 fans?

When using 2 fans, please connect one of the fans to the CPU-Fan header and the second fan to one of the Case-Fan headers of your mainboard. Alternatively, you can also use a 3-pin Y-cable in order to run both fans via the CPU-Fan header. Such cables are available in specialised retail stores.

Le poids élevé représente-t-il un danger pour le processeur central ou le socle ?

Non. Les refroidisseurs Noctua disposent d'un système de montage SecuFirm™ très fiable. Grâce au vissage sûr avec une plaque de montage au dos de la carte mère, le dépassement des recommandations de poids données par Intel et AMD, qui est normal pour les refroidisseurs high end, ne présente pas de danger et est sans inconvénients.
