heading NH-U12 SPECIFICATIONS REVIEWS SERVICE Product discontinued. Successor model: NH-U12F Thanks to the 4 Dual-Heat-Pipes, 38 aluminium cooling fins with a total surface area of more than 5000cm² and soldered joints for optimal heat-transfer, the Noctua NH-U12 achieves superior cooling performance with a 120mm fan of your choice - no matter whether used for super-silent or ultra-high-performance cooling! 4 Dual-Heatpipes for optimal heat absorption The 4 u-shaped Dual-Heat-Pipes have a huge contact area with the copper base to efficiently absorb the CPU's heat. They form 8 risers to spread the heat throughout the fins. 38 aluminium cooling fins for optimal heat dissipation Thanks to a surface area of more than 5000cm², the cooling fins dissipate the heat extremely fast. Both the choice of aluminium and the fins' shape and spacing allow for outstanding cooling performance even with silent fans. Soldered joints for optimal heat-transfer Unlike many other coolers, whose heatpipes are stuck to the base and the fins, the Noctua NH-U12 possesses high-grade soldered joints to ensure optimal heat transfer. Screwless fan-mount including anti-vibration strips The choice of fan is all yours: 120mm fans provide excellent results regardless of whether silence or performance is your primary concern. Attaching the fan with the steel clips is a child's play and doesn't even require a screwdriver. The supplied anti-vibration strips minimize vibrations transmitted to the cooler and hence allows for extra quietness. Universal fit for socket 478, LGA, K8, easy installation, thermal paste The NH-U12 fits Intel socket 478 and LGA 775 as well as AMD K8. The mounting mechanism using a backplate and spring-loaded screws is as easy as it is secure thanks to the detailed step-by-step installation guide. In addition to the mounting hardware, the package contains a syringe of high-grade thermal paste. ✕ See all 71 reviews for this product See all 61 reviews for this product Cooler Specification Socket compatibility Intel Socket 478 & LGA 775, AMD K8 Height (without fan) 155 mm Width (without fan) 124 mm Depth (without fan) 70 mm Height (with fan) 155 mm Width (with fan) 124 mm Depth (with fan) 95 mm Material Copper (base and heat-pipes), aluminium (cooling fins), soldered joints Application P4 all frequencies, AMD all frequencies 12.03.2007 // DarkHardware.com NH-U12 Review Noctua, "havayla soğutmada bir numarayız" diye ortaya çıktı, görünüşe göre iddialarında çok haksız da değiller. Gerçekten bir numara oldukları tartışılır, çünkü bu ürünlerden sonra piyasaya çıkan Titan Amanda gibi bazı soğutucular, Peltier yardımıyla soğutma çizgisini daha da düşürmeyi başardılar. Öte yandan, Noctua NH-U9 ve U12'nin hiç bir rakibinden büyük farkla geride kalmayacağı da açık. Soğutucular bekleme durumunda işlemciyi oda sıcaklığına kadar düşürebiliyorlar, yük altındaysa sıcaklık bizim test sistemi için 40 dereceyi geçmiyor. Sistemimizde eğer Core 2 Duo gibi yeni nesil bir işlemci kullansaydık, herhalde en ağır yükleme sırasında bile 35 derecenin altında sıcaklıklar okuyacaktık. Test verdict: "Özetlemek gerekirse, havayla soğutma alanında piyasaya çok iyi bir marka daha girmiş durumda. Özellikle Thermalright müşterileri, bu yeni ve iddialı markayı da görmeden karar vermemeliler." (Levent Pekcan, DarkHardware.com) 01.03.2007 // PC Games Hardware NH-U12 Review Scheuen Sie den Aufwand nicht und haben sie genug Platz im Gehäuse, so erhalten Sie mit dem Noctua NH-U12 einen Kühlkörper, der sich je nach verbautem Lüfter auch für den leisen Wohnzimmer-PC oder für den übertakteten Spiele-Rechner eignet. Test verdict: "Das Top-Produkt aus unserem letzten Vergleich in PCGH 10/2006 hat nichts an Qualität eingebüßt;" (Henner Schröder, PC Games Hardware) 19.01.2007 // Media-Planet.org NH-U12 Review Gegen diese Werte darf nun jeder getestete Kühler antreten und den Anfang machte der Noctua NH-U 12 in verschiedenen Betriebsmodi (passiv, 1 Lüfter, 2 Lüfter). Auch ohne jeglichen direkten Luftzug konnte er uns mit seinen erreichten Temperaturen durchaus überzeugen, 69°C bei Last (0,713 K/W) und 50°C (0,513 K/W) wenn die CPU wenig zu tun hat. Wenn man nun aber einen neuen Core2Duo verwendet oder aber auch einen HTPC so lautlos betreiben möchte, wird man sicherlich sowieso noch genauer auf die zu kühlende Verlustleistung achten, wodurch die Werte noch ein wenig besser werden. Die besten Ergebnisse erzielten wir selbstverständlich, wenn auch nur mit knappen Vorsprung, mit zwei 120mm Lüftern, die bei uns von der Firma Coolink stammten. Da wir ein unterschiedliches Pärchen geliefert bekommen haben, SWiF Fan 1202/1201 liefen diese immer jeweils bei 1200 Umdrehungen. Zum einen haben wir sie 'durchziehend' montiert und konnten mit 50°C (0,521 K/W) bei Last und einer Idle Temperatur von 37°C (0,384 K/W) sehr gute Werte erzielen. Wenn die Ventilatoren gegeneinander pusteten, stieg auch die Temperatur um jeweils 1K an (0,532 K/W bei Last und 0,395 K/W im Ruhemodus). Wenn man auf das letzte Quäntchen an Leistung verzichten kann, reicht laut unserem Test ein Lüfter völlig aus: 52°C unter Prime95 (0,542 K/W) sowie weiterhin 38°C (0,395 K/W) wenn der PC nichts bis wenig rechnen musste, sind nach wie vor sehr gute Leistungswerte. Test verdict: "Für einen aktuelle Preis von ca. 49,99 EUR erhält man einen ausgereiften Kühlkörper für den es bereits ein Nachfolgermodell (NH-U12F) gibt. Zudem ist er für fast alle Sockeltypen einsetzbar und man kann ihn als Low-Noise Kühler (passiv) oder aber auch als High-End Produkt mit zwei 120mm Lüftern betreiben. In jedem Fall erreicht man bei geringerer Lautstärke bessere Kühlergebnisse als mit Intels-Boxed-Kühler." (René Schröter, Media-Planet.org) 21.12.2006 // Guru3D.com NH-U12 Review I must say that I'm really pleased with the products from Noctua. For now I'll leave the U12 cooler with silent fan on our test system. It's actually working really well and that surely says something about the quality that is being offered here. Other then the sheer size of the product there's nothing negative to report here. Test verdict: "Good stuff for sure, highly recommended." (Hilbert Hagedoorn, Guru3D.com) 16.12.2006 // NGOHQ.com NH-U12 Review As you can see, the Noctua CPU-Coolers, especially the NH-U12, is performing really good, almost as good as the watercooling-kits we tested earlier. Test verdict: "Both units have proven themselves to be excellent products, especially the NH-U12." (Eran Badit, NGOHQ.com) 16.10.2006 // ADSLzone.net NH-U12 Review Dreadnought and his colleague Fergonar from ADSLzone.net have done an excellent Video-Review of the NH-U coolers - thanks for the great work! The video is in Spanish and 61MB in size. Test verdict: "En resumen: Estos disipadores me han dejado completamente anonadados con sus resultados. Silencio y prestaciones, todo en un mísmo paquete... Y parecía imposible!" 09.10.2006 // MaterielPC.net NH-U12 Review Une fois overclocké, le rad box nous fait un record avec 61°C (la limite d'un tel processeur étant de 65°C d'après AMD), quant à notre Noctua, il avale les watts pour dissiper un minimum de 52°C. Test verdict: "Noctua entre directement dans la cour des grands avec un radiateur d'une qualité exemplaire, une solidité des ailettes à toutes épreuves, rien à voir avec certaines autres marques qui se contente de mettre des ailettes aussi épaisse qu'une feuille d'aluminium. Côté performances, elles sont à la hauteur de l'assemblage de ce produit, avec environs 45° à débourser, ça en fait le choix le plus intéressant du moment puisque pour toujours être comparé au xp90c, celui ci coute aussi 45°." (Anthony Alain, MaterielPC.net) 09.08.2006 // GinjFo.com NH-U12 Review De l'emballage à la finition, Noctua a apporté une attention particulière afin de proposer deux produits de hautes qualité. Le NH-U9 et le NH-U12 sont sans reproche laissant une impression de satisfaction lors de leurs achats. La mise en place ne pose pas de problème notable. Ils ont montré au cours de nos tests des capacités étonnantes, laissant derrière eux une des références en termes de performance sur le rapport refroidissement/silence. Je veux bien sur parler du CNPS 9500 LED de Zalmam. L'usage d'un ventilateur de 120 mm pour le NH-U12 apporte un confort agréable et un potentiel important en cas de besoin (Overcloking). Test verdict: "Le constructeur Noctua frappe un grand coup avec ces deux radiateurs." (Jérôme Gianoli, GinjFo.com) 02.08.2006 // ADSLzone.net NH-U12 Review El Noctua NH-U12 mejora todavía más los registros de su hermano pequeño, el NH-U9, pero se deja en el camino el silencio, siendo apreciable el sonido de su ventilador aunque para nada molesto. Y cuando se le pone un ventilador de altas prestaciones como el Silverstone FM-121, realmente nos podemos dar cuenta de lo increible que es este disipador. Si eres fan del overclock (y tu caja lo permite), este disipador ha de estar el primero en tu lista de próximas compras. Realmente imprescindible. Test verdict: En resumen: Estos disipadores me han dejado completamente anonadados con sus resultados. Silencio y prestaciones, todo en un mísmo paquete... Y parecía imposible! 18.07.2006 // BleedinEdge.com NH-U12 Review [W]hile the Hyper 6+ beat the stock cooler temps, the Noctua NH-U12 shattered them. A six degree difference in load temps is outstanding for an out of the box configuration. Test verdict: "The NH-U12 certainly wins this round..."

Can I keep using the backplate / mounting system of my previous Noctua cooler for my new one? 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. 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 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. Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)? The following models include a mounting-kit for socket AM4 and are thus compatible out of the box: NH-D15 (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-D15 SE-AM4 NH-D15S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-U14S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-U12S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-U12S SE-AM4 NH-U9S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-D9L (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-C14S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-L12S NH-L9x65 (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-L9x65 SE-AM4 NH-L9a-AM4 The following models can be made compatible with the AM4 socket free of charge using the NM-AM4 upgrade-kit: NH-C12P NH-C12P SE14 NH-C14 NH-C14S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-D14 NH-D14 SE2011 NH-D15 (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-D15S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-D9L (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-L12 NH-L9x65 (AM4 mounting included since 2019, only older coolers require upgrade kit) 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 AM4 socket free of charge using the NM-AM4-UxS upgrade-kit: NH-U14S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-U12S (AM4 mounting included since 2019, only older coolers require upgrade kit) NH-U9S (AM4 mounting included since 2019, only older coolers require upgrade kit) The following models can be made compatible with the AM4 socket free of charge using the NM-AM4-L9aL9i upgrade-kit: NH-L9a NH-L9i The following models can be made compatible with the AM4 socket using the NM-AM4 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!) NH-U12DX NH-U12DX 1366 NH-U12DX i4 NH-U9DX i4 NH-U9DX 1366 NH-U9DO (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 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!) NH-U12DX NH-U12DX 1366 NH-U9DX 1366 NH-U9DO (Note that the A3 version is not compatible!) The following models are not compatible with the LGA2011/LGA2066 sockets and can not be upgraded: NH-L9a NH-L9i NH-U12DO A3 NH-U9DO A3 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). How much space between mainboard and power supply is required when the NH-U12 is installed upright? When installed upright (see picture below), the NH-U12 may jut out over the upper edge of the mainboard. In this case, the gap required between the upper edge of the mainboard and the power supply in the case is (depending on the position of the CPU socket on the mainboard) up to 25mm. Measured from the upper mounting holes of the CPU socket, the required distance to the power supply unit is 35mm. 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: 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. Do you have a question concerning one of our products? Please use this form to pose a question! Disclaimer:We create and update our compatibility lists with the utmost care. 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.
