Le NH-L12 est un ventirad peu encombrant et silencieux spécifiquement conçu pour les petits boîtiers et les configurations HTPC. Le système de ventilation PWM, articulé autour du couple NF-F12 (120mm) / NF-B9 (92mm), permet au NH-L12 de tirer partie de la puissance maximale (mode dual) ou bien d’opter pour un encombrement ultra-compact de 66mm (ventilateur supérieur enlevé). Livré avec la célèbre pâte thermique NT-H1 et un kit de fixation multi-socket SecuFirm2™ de Noctua, le NH-L12 est un produit tout-en-un qui rassemble tout le nécessaire pour un refroidissement haut de gamme silencieux.

  Attention:  Le NH-L12 est un ventirad silencieux de taille réduite destiné aux boîtiers SFF (Small Form Factor) et aux environnements HTPC. S’il offre une performance de premier ordre dans sa catégorie, il n’est néanmoins pas indiqué pour l’overclocking et exige une certaine prudence avec les CPU dépassant une TDP (Thermal Design Power) de 95W. Merci de consulter le guide TDP afin de déterminer si votre CPU est compatible avec le NH-L12

NH-L12 Commentaire

The NH-L12 from Noctua was a little surprise for me. With all the caveats, provisos, a couple of quid pro quo, I felt the little guy wouldn’t hold up to the heat. It did, and for users that have a smaller/narrower case and not interested in the least to overclock then the NH-L12 would be rather perfect. Top it off with Noctua’s 6 year warranty and awesome build quality, the NH-L12 has win all over it. [...] The HTPC and SFF crowd stands to benefit the most from the NH-L12. The overall height is rather low at 3.7 inches with both fans installed. Removing the upper 120mm fan lowers that to 2.5 inches. Couple the small overall size with the quiet operation of the Noctua fans, makes it perfect for HTPCs or Small Form Factor builds where low noise is a goal.
Verdict du test: "If you are in the market for a quality quiet low profile CPU cooler, then Noctua has you covered with the NH-L12." (Shane Higgins, LegitReviews.com)

+ Hohe Kühlleistung mit zwei Lüftern
+ Hervorragende Hardwarequalität
+ Leise Serienbelüftung
+ Umfangreiche Ausstattung
+ Moderater Platzbedarf
Verdict du test: "Das beste Gesamtpaket aller Testkandidaten wird unserer Ansicht nach durch den Noctua NH-L12 verkörpert. Der erstklassig gefertigte Down-Blower überzeugt durch gute Kühlleistung in Verbindung mit einem bei Bedarf zurückhaltend leisen Betriebsgeräusch und ist dank 120-mm-Konzeption erheblich kompakter als die Kontrahenten von Phanteks oder Alpenföhn. Typische Kritikpunktkategorien wie die mangelnde Qualität der Serienlüfter, Komfortabstriche beim Montagesystem oder potentiell fehlende Ausstattungsmerkmale umschifft Noctua beim NH-L12 zielsicher, sodass wir in der Summe eine klare Kaufempfehlung für den knapp 50 Euro teuren Österreicher aussprechen können."

Noctua have been able to create a steady stream of high grade coolers over the years, and the NH-L12 is no exception to the rule. We managed to maintain a substantial 4.7 GHz overclock via the NH-L12 without experiencing high temperatures that could affect the longevity of the CPU. This is quite remarkable for a compact, low-profile CPU cooler especially as compromises normally have to be made. The impressive thermal performance of the cooler is rivaled by the excellent acoustic performance. Even with the fans running at full speed, the cooler is inaudible when it’s installed in a case. That said, both of the fans are PWM models, so most of the time they will be spinning much slower, emitting low levels of noise. Noctua offer a 6 year warranty as standard which gives us peace of mind that the cooler will last a very long time indeed.

To my surprise this cooler worked exceptionally well, even at full system load. With the 2 fans on full speed the idle temperature was 31 and the load was 47, which is very impressive for such a small cooler. Even more impressive is when I took the top fan off to run the cooler in “low-profile” mode the temperature only went up 10 degrees (41 idle, 57 load). This cooler is extremely small. You really should not have any issues fitting it inside your case or HTPC system. I installed the cooler on my ASUS P9X79 Pro motherboard without any issues at all. The heatsink is large enough that you can actually fit most memory that has smaller heatspreaders under it. Also if you are having height clearance issues you can take off the top fan for a very low-profile cooler that still provides great cooling.
Verdict du test: "Right now the NH-L12 is selling for $71.99 at my favorite online retailer. At this price it is at the higher-end of air coolers, but in the end I do think that it is worth it if you are looking for a superior low profile CPU cooler that is very quiet in operation and can be mounted quite a few different ways."

NH-L12 Commentaire

The stock run delivered a terrific result for a cooler of this size and design. 57 degrees might be a bit higher than normal, but look at how little of a cooler is doing this job. As for the overclocked run, I think the NH-L12 did a really admirable job handling over 125 watts of power being delivered to this 95 watt cooler. Yes, 80 degrees is warm, but considering the abuse level, I am pleased with these results. [...] Silence and performance are what we expect from anything Noctua and they prove that you don't need a humongous cooler in the build to get either of them. With a trend from most manufacturers showing that bigger is usually more quiet and usually performs better, the NH-L12 outdid the Enermax solution and the Enermax solution is a much larger cooler and isn't as easy to install as this is. [...] I can take this cooler off the test bench and slam it into some of the tiniest HTPC solutions, it doesn't interfere with the memory and even when abused well beyond its specified limits, it takes it well. Even if you don't need a cooler that can get under a 66mm height clearance issue, the NH-L12 has its place in almost any build, so it is well worth considering this for its silence and its ability to handle almost any CPU cooling situation.
Verdict du test: "It has two silent fans. It is convertible. It fits in almost any situation. There is very little reason not to buy the underrated NH-L12 from Noctua, it's just too handy of a cooler not to have on hand." (Chad Sebring, TweakTown.com)

Mit dem NH-L12 kann Noctua ein weiteres Mal einen hervorragenden Prozessor-Kühler präsentieren. Wer durch geringe Platzverhältnisse im PC-Gehäuse eingeschränkt ist, kann die Höhe des ohnehin schon sehr flachen Kühlers mittels der Demontage des oberen Lüfters nochmals um rund 25 Millimeter reduzieren. Vor allem für HTPCs dürfte dies interessant sein, da hier nicht das letzte Quäntchen Kühlleistung ausschlaggebend ist, sondern eher ein platzsparender und leiser Kühler.

We have seen a number of Noctua products in the past and on each occasion have been impressed by the build quality and design with more recent models excelling on both fronts. With the NH-L12 Noctua continue to impress and the cooler looks and feels high quality. Each of the components is soldered together well, the finish is exceptional and the fans fit perfectly to the heatsink. We also love the colour scheme that Noctua use, it looks great. In terms of installation the product is essentially flawless. We can install the cooler in less than ten minutes from start to finish and at each step Noctua make the process easy, whether that is down to the clear instructions, perfectly fitting components or thoughtful design such as the holes in our heatsink fins to pass the screwdriver through. We also appreciate the extra thought taken to supply screws for mini-ITX boards and socket 2011, ensuring every consumer is catered for... something which is further enhanced by the low profile option. For performance Noctua again excel, giving us low noise on the standard wires and adapters to lower it further if we wish. PWM compatibility is also present and the temperatures recorded on this heatsink are class leading. That brings us to value where the great bundle of extras means we have everything needed, regardless of the system, and a 6-year warranty tops it off.

NH-L12 Commentaire

First off, you need to understand what the Noctua NH-L12 is….and isn’t. The NH-L12 is a low profile, dual fan cooler made specifically for small case applications, most notably HTPC. It has the ability to run in a single fan mode that drops the height of the installed NH-L12 to a miniscule 66mm. It is not a behemoth made for overclocking. It is specifically meant to sit on lower wattage CPU/APUs in tight spaces and cool them effectively and efficiently in near silence, and do so in even the smallest and tightest of HTPC cases with a simple installation. This is what the NH-L12 was made to do, and it does it to perfection with room to spare. Looking at the cooling characteristics, they are absolutely outstanding. In dual fan mode the NH-L12 actually manages easily outperform its much larger sibling the NH-C12P and is in a whole different (and much better) cooling class than the other low profile coolers we have tested. At stock CPU speeds the NH-L12 cooling results look like they came from a similarly priced full sized tower, and a good one at that. Taking off the top fan and running the NH-L12 at 66mm in height, the cooling naturally took a hit, but remained impressive. Even under full load for extended periods, the CPU remained 14 degrees from its thermal danger zone at a cool 41 degrees.
Verdict du test: "Put it all together, and we have what I feel is the finest low profile cooler to hit the market to date in the Noctua NH-L12. It is a stellar performer, beautifully built and engineered and simple to install. The NH-L12 stays dead quiet at all fan speeds, and even offers an LNA for those situations where even the minutest noise would be too much. Plus, it fits everywhere. In the world of HTPC/Low Profile cooling, the Noctua NH-L12 is king, and in my mind, it’s not even close." (George Cella, HiTechLegion.com)

NH-L12 Commentaire

This is my first encounter with a Noctua CPU cooler here at eTeknix and I can honestly say I am thoroughly impressed with the Noctua NH-L12. As always I’ll start off by revealing to you the price, if you don’t already know. The Noctua NH-L12 costs £43 from Scan, and between £40-50 more broadly from other retailers. Thus you can safely say this Noctua CPU cooler occupies a high end part segment of the market, priced similarly to other high performance CPU coolers. Being a Noctua product, it is widely available across Europe and North America as Noctua are a big brand in the world of computer cooling. At that price you are getting a unique , yet cost effective proposition. On the one hand you have a CPU cooler that is compact enough to fit into the smallest of systems of mini-ITX, micro-ATX and ATX form factors, and on the other you have a CPU cooler that is capable of running Ivy Bridge at 4.5GHz without breaking into a sweat. We agree if you consider other cooling solutions for the same price, the performance is below-par however this is a foolish way of looking at it since this cooler is specifically designed for small form factor systems where the height of your CPU cooler is an important consideration. You wouldn’t spend £6000 on an Nvidia Quadro GPU and complain it sucks at running games, so why make a similar mistake here?
Verdict du test: "Acoustic performance was excellent, and we really can’t rave about how good it was. The Noctua NH-L12 was probably the quietest CPU cooler we have ever tested. Add to that the fact it looks the business, is extremely high quality, offers highly competitive performance for its unique form factor and is well priced. Awarding the Noctua NH-L12 is a tough one. It could have our innovation award for being such a unique product in the HTPC/SFF market. It could snatch the Bang For Buck award for being one of the best performing and best value HTPC cooling solutions on the market we have ever seen. Yet the Noctua NH-L12 ticks so many boxes that we feel it is more than deserving of our highest award, the Editor’s Choice award." (Ryan Martin, eTeknix.com)

Trotz der sehr kompakten Abmaße besitzt der Winzling von Noctua mit zwei Lüftern bestückt ausreichende Leistung, die selbst moderates OC von Prozessoren mit 130 Watt TDP ermöglicht. Nur extreme Settings erlaubt der Kühler nicht, was wenig verwundert. [...] Die Lautstärke gefällt ebenfalls. Beide Lüfter laufen angenehm und fallen dank der guten Lager sowie der Entkopplung akustisch nicht auf. Selbst die Maximaldrehzahl ist lediglich hörbar, aber keinesfalls störend laut. Das Zubehör fällt wie die Verarbeitung gewohnt edel aus. Selbst an Entkoppler, um einen der Lüfter im Gehäuse zu montieren, wurde gedacht. Die bewährte, zweistufige SecuFirm-Halterung lässt ebenso wenig zu wünschen übrig und gewährleistet zusammen mit den verbesserten Lüfterklammern einen hohen Benutzerkomfort. [...] Der NH-12 ist deshalb für Besitzer kleiner oder sehr kleiner Gehäuse eine gute Wahl.

In which orientation should top-flow coolers (NH-C series, NH-L12) be installed?

When using top-flow coolers in a tower-style case, we strongly recommend installing the cooler with the heatpipes in horizontal position or with the bends of the heatpipes pointing downwards. Please avoid installing the cooler with the bends pointing upwards as this may result in reduced cooling performance. In desktop cases, the cooler can be used in any orientation.

Orientation

How 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

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

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 independent from the second fan’s rpm signal.

I get a CPU fan error despite the fan is running!

Some mainboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.

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).

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.

How big is the NH-L12 and how much clearance does it provide?

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

P14

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

Is it possible to install the supplied NF-F12 or other 120mm fans underneath the fin stack?

The NF-B9 92mm fan is used underneath the fin stack because it gives easy access to the mounting screws and sits within the 95x95mm (Intel) and 96x114mm (AMD) keep-out zones, thus providing full compatibility with standard height RAM and chipset/VRM heatsinks. In principle, it is also possible to put the supplied NF-F12 120mm fan underneath the fin stack instead, but in many cases, this setup will cause compatibility issues with RAM and/or chipset/VRM heatsinks. Similar issues are likely to arise with other 120mm fan models and in addition, some fans may be blocked by the mounting screws and/or block access to the screws. As a result, using 120mm fans underneath the fin stack may be possible in some cases, but is not officially supported.

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. 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.

Is the cooler compatible with AMD FM2+?

As the hole spacing for CPU cooler installation on FM2+ is the same as on AM2, AM2, AM3(+), FM1 and FM2, the cooler is fully compatible with FM2+ out of the box and doesn’t require any modifications or upgrades.

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.

My Noctua PWM fan starts to spin when the PC boots but then stops, what is wrong?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). In this case, it may occur that the mainboard reduces the voltage so much that the fan stops. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.



To resolve the issue, you can:

  1. Choose a higher fan speed profile in the BIOS (e.g. „normal“ instead of „silent“, etc.) or deactivate automatic fan speed control and use a Low-Noise Adaptor instead.

  2. Use the mainboard‘s fan speed control software or 3rd party tools like Speedfan to regulate the fan speed. Unlike BIOS based fan speed control, the supplied software usually checks whether the fan has stopped and increases voltage accordingly or at least offer more options to set up the fan properly.

  3. If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?

The specified minimum speed refers to the speed at 20% PWM duty cycle. There can be several reasons why the fan doesn‘t go as low as indicated:

  1. Many mainboards do not go below 40%, 50% or even 60% PWM duty cycle on case fan headers. Please refer to your mainboard manual to verify whether the fan header actually goes down to 20% duty cycle. If that's not the case, in some cases you can use the fan speed control software supplied with your mainboard to overcome these limitations and reduce the fan speed even further. However, 3rd party tools like SpeedFan offer greater flexibility and better options to work around the limitations imposed by the mainboard vendors.

  2. Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

    4 pin fan header types

    Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM.

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.

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

Systems from Dell, HP or Lenovo often use motherboards which differ slightly from the specifications issued by Intel and AMD. While those changes are usually subtle, they can led to compatibility issues with coolers that where built to comply with these specifications.

Even in case the cooler is mechanically compatible and can be instaled, 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 can often not be resolved.

Due to the large number of possible issues with systems from Dell, HP and Lenovo, which can't be resolved with different mounting parts alone, Noctua does not officially support such machines.

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 Intel -K series CPU is running too hot although my heatsink supports the specified TDP, what's the problem?

Intel's unlocked -K series CPUs can dissipate more heat than indicated by the TDP specification if a) the TDP limits are extended or disabled in the motherboards' BIOS or b) the motherboard applies some overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers. This can lead to temperature issues.

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 and notice a higher than specified power draw, please limit the TDP to the specified value by choosing appropriate BIOS settings. In doubt please contact your motherboard vendor for details on how to do this.

All our TDP recommendations are based on thorough testing with the default values specified by Intel.

Is the cooler compatible with the LGA1151 socket?

Yes. Due to the heatsink mounting mechanism being identical on LGA1150, LGA1151, LGA1155 and LGA1156, the cooler also supports LGA1151.

Why doesn't the supplied backplate fit my LGA2011 motherboard?

The supplied backplate is for LGA115x only and there is no backplate required for installation on LGA2011. Please refer to the installation manual for how to install the heatsink on LGA2011.

My case supports CPU coolers of up to XXXmm height, which model should I choose?

Please refer to our TDP guide in order to select the cooler that offers the best cooling performance at a given height.

Can I use Low-Noise Adaptors with y-cables / multiple fans?

Yes, Low-Noise Adaptors (L.N.A.s) can be used with y-cables, but please make sure to use one L.N.A. per fan and to place the L.N.A.s between the y-cable and the fans as shown below. Never use one L.N.A. for two (or more fans) by placing it between the mainboard and the y-cable!

Pourquoi le fond du refroidisseur Noctua n'est-il pas brillanté et poli ?

Etant donné que la plupart des enthousiastes d'ordinateurs personnels utilise encore aujourd'hui des pâtes thermiques à forte viscosité, le fond du refroidisseur Noctua a été optimisé pour l'utilisation de ces pâtes. Les fines rainures (micro-grooves) dans la surface du fond du refroidisseur Noctua permettent d'appliquer les pâtes thermiques à forte viscosité de manière homogène en une couche ultramince et sans aucune inclusion d'air n'existe entre le refroidisseur et la processeur central. Le risque d'une application non homogène serait beaucoup plus élevé si la surface était brillantée et polie. Des couches de pâte thermique trop épaisses et des inclusions d'air altérant sensiblement la transmission calorifique, les micro-rainures sont d'une importance décisive pour la performance de refroidissement totale du refroidisseur Noctua en cas d'utilisation des pâtes thermiques courantes à forte viscosité.

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:

I have difficulties installing the cooler, can you help?

Please refer to the installation manual and our video installation guides for detailed instructions on how to install the cooler.

Should I take the cooler off before transporting my system?

Due to the low weight of the cooler, it is not necessary to take it off for transport.

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).

You specify airflow in m³/h, how can I convert to CFM?

In accordance to the International System of Units (SI system), Noctua specifies volumetric flow rate (airflow) using the SI unit of cubic metres per hour (m³/h). The SI unit can easily be converted to cubic feet per minute (CFM): One m³/h is ~0.589 CFM and one CFM is ~1.699 m³/h. For convenient conversion, online tools such as www.convertunits.com can be used.
