Our recording equipment did measure around 22dBa. Moving to low noise and ultra low noise adapters brought further reward with dBa recordings of 16.8dBa and 16.2dBa respectively – clearly our equipment and testing room would need further improvement to measure more accurate dynamics at these settings. Test verdict: "Once again Noctua have created a phenomenal cooler which is without a doubt one of the best solutions for this market we have yet to test on KitGuru." (Allan Campbell, KitGuru.net) 18.12.2009 // OverclockersClub.com NH-U9B SE2 Review While shorter in stature and overall bulk, the NH-U9B Special Edition delivers decent results. At stock speeds it allows the processor to run a full 10 degrees Celsius warmer than the NH-D14 that in and of itself is an accomplishment considering it ran within 5 degrees Celsius of the TRUE and NH-U12P. [...] This heatsink as delivered, is dead silent. If that's not silent enough, then you can install the Low Noise and Ultra Low Noise Adapters onto the NF-B9 fans to further drop the fan speed and noise. Priced at 55 bucks, this heatsink is not the most inexpensive, but quality components do come with a premium. As a heatsink that uses 92mm fans, it delivers performance that exceeds that of some of the other heatsinks I have used in the past and compares well with some of the cooling behemoths on the market. Test verdict: "Much like its larger brethren, the NH-U9B Special Edition is a high quality heatsink with a ton of technology behind it. From the SSO bearings and Vortex Control Notches on the fans, to the build quality and darn-near universal SecuFirm2 mounting mechanism, to the NT-H1 thermal paste - it is all designed for a purpose. That purpose is to deliver excellent cooling capabilities, while keeping noise to a minimum. This goal, Noctua has been successful in achieving. I was impressed by its ability to hang as close to heatsinks that honestly are the cream of the crop." (Frank Dimmick, OverclockersClub.com) 14.06.2010 // TechPowerUp.com NH-U9B SE2 Review Noctua's NH-U9B SE2 has proven to be a decent performer. Its quality and bundled accessories set it apart from the rest of the competition. As usual, Noctua has bundled the cooler with easy to install mounting hardware for almost every current CPU socket along with a pair of excellent 92 mm fans, thermal grease, and tools to make installation a breeze. The included fans are near silent at normal 12V operation but there are also four voltage regulation adapters that, when utilized, drop the fan to 7V, or 5V to further decrease fan noise. Noctua's design also provides airflow for components around the CPU socket to aid in cooling of secondary heat sources. The cooler comes with a durable Nickel plated finish that is both functional and attractive to score in the looks department. Should you run into any problems, Noctua provides a six year warranty on all their coolers. Test verdict: "Overall, the Noctua NH-U9B SE2 is a great choice for anyone in need of a fairly compact cooler seeking good cooling capacity while remaining near silent. It costs a few bucks more than other offerings but that can be justified after taking in consideration the quality put into all of Noctua's products." (Steve Harris, TechPowerUp.com) 01.01.2010 // WCCFtech.com NH-U9B SE2 Review After going through the design and test review of the cooler there is no doubt that the cooler performs very well when it is put in its intended milieu. When paired with a processor running at stock speed, the cooler can keep the processor in a safe temperature envelope even without using any fans Even when the cooler is paired to an over clocked heat guzzling Core i7, it does not disappoint. The cooler was able to keep the processor under 80C. Remember that Linpack test generates massive amounts of thermal energy. Under normal operation the temperature would be much better. Test verdict: "If you in the market for a cooler that would help you assemble a nearly silent HPTC you wont find a cooler better than the NH-9UB SE2." (Ali Tayyab, WCCFtech.com) 27.07.2012 // Hexus.net NH-U9B SE2 Review The NH-U9B SE2 bundle is exemplary, and the heatsink oozes quality too. The serrated aluminium fins look impressive and are said to reduce turbulence, the Noctua logo is neatly engraved into the top of the heatsink, and the four nickel-plated copper heatpipes attach to a silky-smooth contact plate. Test verdict: "Noctua's NH-U9B SE2 oozes quality" (Parm Mann, Hexus.net) 03.07.2016 // Passion-Hardware.com NH-U9B SE2 Review Niveau performance le NH-U9B s’en tire bien avec un delta T de 32° (Tcpu = 59]) sur notre Xeon E5-2670 de test (dont le TDP réel frôle les 115W). La ventilation étant réglée en automatique, les ventilateurs se font oublier dans le bruit ambiant du boitier. Ces performances promettent une marge confortable d’OC sur des cpu à plus faibles TDP comme les i5-xxxxK Intel. Test verdict: "Un bundle complet, une qualité exceptionnelle, un montage des plus simples et des performances au rendez-vous, ce ventirad de petite taille a tout pour plaire et ravira les utilisateurs exigeant ayant besoin d’un refroidissement fiable et compact. Il trouve d’ailleurs sa place dans mon serveur en tant que ventirad permanent !" (Alessandro Gallo, Passion-Hardware.com) 24.10.2014 // HWready.it NH-U9B SE2 Review I dissipatori dell’azienda Austriaca restano sempre un punto di riferimento, qualità altissima e curati nel minimo dettaglio. Ventole fantastiche, 2 presenti in questa Special Edition dell’NH-U9B (che già sono un valore aggiunto al dissipatore stesso). Il Bundle è completo, dal logo adesivo rigido (stupendo!), i kit di installazione AMD ed Intel, cavi per la personalizzazione della velocità delle ventole e l’ottima pasta termica NT-H1. Test verdict: "Buone prestazioni e silenziosità in dimensioni ridotte. Acquisto assolutamente consigliato, garantito!" (Santoro Luigi, HWready.it) 24.06.2014 // hard-h2o.com NH-U9B SE2 Review Desde que tenemos el gran honor de poder probar los disipadores de Noctua, sabemos que son sinónimo de tranquilidad. Los austriacos hacen un trabajo espectacular tanto con el diseño de los disipadores, como el de los ventiladores, esto último infravalorado por su gran importancia. El fabricante nos da 6 años de garantía y eso es confianza en su propio trabajo que deriva en confianza de sus clientes; el rendimiento de este disipador es indiscutible, aunque para equipos donde queramos más OC y bajas temperaturas, tendremos que acudir a modelos más grandes, como las series de 14 y 15, con ventiladores y estructuras más grandes. Pero este modelo está indicados para equipos compactos, como mini-torres o equipos multimedia, todo ello sin descuidar su misión, que es la de enfriar nuestra CPU, y lo hace realmente bien, con una sonoridad excelente. Lo mejor de todo es que no forzamos nuestra CPU, podremos tener aún menos sonoridad, al poder usar los adaptadores que frenan la velocidad de los ventiladores. Un 10 para su sistema de montaje, por supuesto, fácil de instalar, y no menos importante, fácil de quitar. Test verdict: "El NH-U9B SE2 de Noctua hace un trabajo espectacular, bajas temperaturas, indicado para sistemas compactos y con una garantía de 6 años (incluidos ventiladores) de funcionamiento inigualable." (David Portero, hard-h2o.com) 02.06.2014 // Tweaks.pl NH-U9B SE2 Review Ten niski tower jest w stanie sprostać i5 2500K@4,7GHz! Biorąc pod uwagę prosty montaż, dość ciche wentylatory i 6 lat gwarancji to bezsprzecznie NH-U9B SE2 możemy ocenić na 5/5 oraz przyznać mu rekomendację w aż trzech kategoriach: jakość, wydajność, kultura pracy! Test verdict: "Noctua NH-U9B SE2 to również bardzo udany cooler." (Marcin Żyto, Tweaks.pl) 21.05.2014 // ThinkComputers.org NH-U9B SE2 Review We know Noctua for some of the best air coolers out there, but normally their coolers are quite large and are made for full-size PC builds. It is much harder to shrink down an air cooler and still have the same type of performance. Well it looks like Noctua was able to do that with the NH-U9B SE2 cooler. This makes it perfect for a small form factor gaming machine where you still want that great performance and might even be overclocking your processor. Now on the other hand if you wanted this cooler for say a HTPC setup it does come with both a low noise adapter and ultra low noise adapter which will slow the fan speed down making the cooler much more quiet. Test verdict: "If you are looking for a smaller air CPU cooler this is definitely one that you should check out."

Is the cooler compatible with the Intel LGA2011 socket and Asus X-socket™? The cooler's fans always run at full speed and can not be controlled by my motherboard, what's the problem? Can the cooler be installed turned by 90° on AMD sockets? In order to install the cooler turned by 90° on AMD, the optional NM-A90 kit is required. 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 firstname.lastname@example.org 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). 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 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. 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. The following models include a mounting-kit for socket LGA2011/2066 and are thus compatible out of the box: NH-C14S NH-D14 SE2011 NH-D15 NH-D15S NH-D9L NH-L12 NH-L9x65 NH-U12S NH-U12DX i4 NH-U14S NH-U9DX i4 NH-U9S The following models can be made compatible with the LGA2011/LGA2066 sockets free of charge using the NM-I2011 upgrade-kit: NH-C12P NH-C12P SE14 NH-C14 NH-D14 NH-D15 SE-AM4 NH-U12S SE-AM4 NH-L9x65 SE-AM4 NH-U12 NH-U12F NH-U12P NH-U12P SE1366 NH-U12P SE2 NH-U9 NH-U9B NH-U9B SE2 NH-U9F The following models can be made compatible with the LGA2011/LGA2066 sockets using the NM-I2011 upgrade-kit but are not eligible for Noctua‘s free mounting offer, so users have to purchase the kit at local resellers: NH-U12DO (Note that the A3 version is not compatible!)

The following models are not compatible with the AM4 socket and can not be upgraded: NH-U14S TR4-SP3 NH-U12S TR4-SP3 NH-U9 TR4-SP3 NH-U12DO A3 NH-U9 DO A3 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. Is it possible to use the cooler with vertical graphic cards? Depending on the chassis, card and motherboard being used, installing PCIe cards in a vertical position using riser cards may cause compatibility issues with CPU coolers. Whether there will be a problem or not depends on the exact position of the card (which is determined by the PC case and/or optional vertical GPU holder bracket), the width of the card as well as the position of the CPU socket on the motherboard. In order to verify that there is sufficient space for the cooler, please measure the distance between the centre of the CPU socket and the top of the PCI card in order to make sure that the cooler fits. 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. 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. Is it possible to mount fans with a greater height than 25mm? Yes. The fan mounting clips grip to the screw holes in the lower edge of the fan frame and hence work with all fans regardless of their height. However, problems with the mounting of the fan can occur due to other parts within the case or fans with special frame designs, where the clips can't grip to the screw holes in the lower edge of the frame. Is it possible to run two fans at a time? Yes. Using the 4 supplied fan clips, you can mount two 120mm fans on the NH-U12(F/P) and two 92mm fans on the NH-U9(F/B). Should the fan be mounted sucking away from the heat-sink or blowing onto the heat-sink? Please install the fan blowing onto the heat-sink. If you're using two fans, please install them so that one blows onto the heat-sink and the other sucks the air away from the other side. On which side of the heat-sink should the fan be installed? Please install the fan so that the hot air can be disposed as good as possible either through the rear case fan (Airflow Option 1) or through the power supply (Airflow Option 2). Is it possible to cool my CPU without a fan (passive) using Noctua coolers? Noctua coolers weren't originally designed for passive operation although the cooling performance is sufficient in many cases. Unfortunately, it is impossible for us to indicate whether a certain CPU can or cannot be cooled without a fan, as this depends on various factors such as case temperature, case ventilation or the orientation of the socket. Generally, we recommend using a fan in the first instance and then lowering RPM while constantly monitoring the temperature. How to install the fan using the supplied steel clips? First hook the clip into the notch of the heatsink: Then hook the endings of the clips into the mounting holes of the fan: What can I do if the fan blocks my RAM or chipset cooler? In order to increase clearance, you can easily move the fan up a few fins as show below: 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. Help, the base of the cooler doesn’t make contact with the CPU / there is no contact pressure! Please verify that you have installed the fastening brackets correctly: 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. 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. 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. 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. 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. Do you have a question concerning one of our products?

Unfortunately, mainboard manufacturers tend to change certain components and heatsinks without pointing it out by using corresponding revision names. If you run into problems while installing our coolers on one of the mainboards listed as being compatible, please don't hesitate to contact our support team at email@example.com.Please also keep in mind that other components such as narrow or small cases as well as memory modules with special (higher) heat-spreaders can cause compatibility-issues.For use in systems from Dell, HP or Lenovo, please note this FAQ. Our case compatibility list helps you to quickly identify which PC cases offer sufficient clearance for which Noctua CPU coolers. The compatibility indication is based on the height of the coolers (including fans) as well as the maximum CPU cooler height specification given by the chassis manufacturer. Caution: Please note that the fans of some tower coolers (especially larger models with 140mm fans, e.g. NH-D15 or NH-U14S TR4-SP3) may overhang the RAM slots and that this can cause compatibility issues if RAM modules taller than 32mm are used. While the fans can be moved upwards to increase RAM clearance, this will increase the total height of the cooler and thus requires additional clearance inside the chassis. As a rule of thumb, if the fan overhangs the RAM, the maximum CPU cooler height specification of the case must be at least the size of the fan plus the height of the RAM minus 7mm (accounting for the height of the socket and CPU). For example, if a cooler uses a 140mm fan that overhangs the RAM and 46mm tall RAM modules are used, the max. CPU cooler height specification should be at least 179mm (140+46-7=179). For further information and instructions on how to move up the fan for each cooler model, please click the height specification link. Disclaimer: We create and update our compatibility lists with utmost care. However, case manufacturers sometimes change parts or details of their products without prior notice or explicitly indicating a revision. Therefore, Noctua cannot accept any liability, nor in any other way be held responsible, for the following compatibility information. When modern CPUs use their turbo modes, they can (depending on the configuration of the UEFI BIOS) dissipate much more heat than indicated by the manufacturer’s TDP (Thermal Design Power) specification. Just like manual overclocking, this puts higher demands on the cooling solution. Our CPU compatibility list helps you to choose the cooler model that is best suited for a given CPU and your individual requirements as far as turbo and overclocking headroom are concerned. We classify our coolers according to the following categories: best turbo/overclocking headroom medium turbo/overclocking headroom low turbo/overclocking headroom compatible without turbo/overclocking headroom compatible with certain restrictions (see comment) incompatible (see comment) For further information on CPUs exceeding their TDP ratings and how to configure the UEFI BIOS in order to avoid excessively high temperatures, please see this FAQ. Please also see our general buying guide, motherboard compatibility list and FAQs for further help on how to select the best cooler for your configuration.
