Die Qualität des Noctua NH-C12P ist ferner über jeden Zweifel erhaben und so bleibt uns wiederum nur, auch Österreichs Top-Blow-Pendant und sein piekfein aufeinander abgestimmtes Bundle mit unserer ComputerBase-Empfehlung auszuzeichnen. Test verdict: "Der Noctua NH-C12P konnte die hohen Erwartungen, die durch die famose Vorstellung seiner NH-U12P-Schwester entstanden, in – für den Top-Blow-Bereich – beachtlicher Weise erfüllen. Die österreichische Entwicklung wartet mit einem für Kühler dieser Bauart exzellenten Leistungscharakter auf und stellt so manchen Tower-Kontrahenten in den Schatten. Seine Lautstärkeeigenschaften überzeugen aufgrund des NF-P12-Premiumlüfters in allen Lebenslagen durch die kaum vorhandenen Motoren- und/oder Vibrationsgeräusche und den sicher geführten Luftumschlag." (Martin Eckardt, Computerbase.de) 02.04.2009 // Custom PC NH-C12P Review Under full load, our test CPU was 9°C cooler with the Noctua than it was with the reference HSF. The Noctua also made little audible noise. This is a great effort considering that we use an overclocked and overvolted quad-core Xeon 3210. The Noctua is a luxury product, and every component of the cooler is of a high quality. Test verdict: "Every part of this cooler screams premium and luxury. [...] If VRM cooling is a priority and you have the cash to spare, this is an excellent cooler." (Mark Mackay, Custom PC) 05.05.2008 // DragonSteelMods.com NH-C12P Review The tower, 'U' style tower coolers seem to dominate when it comes to effectively cooling a CPU, but the NH-C12P changes that now and we have here something small that will fit in most any case that out performs coolers that are essentially twice its size (at least in height). Noctua proves time and time again that they know what they are doing, be it a fan or a CPU cooler, they know cooling and know how to make a quality product. The NH-C12P continues the Noctua tradition of creating and producing high quality, excellent performing products, I can easily recommend this CPU cooler to anyone looking for a quality product that not only looks great but performs exceedingly well. Test verdict: "The Noctua NH-C12P is a great choice for those looking for a small CPU cooler, it offers a nice combination of performance and silence, it could be perfect for an HTPC case or desktop style case. Considering its performance though, the NH-C12P is ideally suited for pretty much any application, and it should be able to handle anything thrown at it." (Kristofer Brozio, DragonSteelMods.com) 05.05.2008 // TT-Hardware.com NH-C12P Review En effet, le NH-C12H déploie une surface d'un peu plus de 2000 cm² contre approximativement 3100 cm² pour le NH-U12P. Ce dernier dispose donc d'une surface d'échange 50% plus grand... Etant donné que les NH-U12P et NH-C12P maintiennent le processeur à une température comparable, on ne peut être qu'impressionné par le travail accompli. Test verdict: "Que penser de ce NH-C12P ? Les performances brutes, c'est-à-dire les capacités de refroidissement du processeur, sont excellentes et comparables à celles du récent NH-U12P. Les deux heatpipes supplémentaires permettent donc de compenser la surface d'échange réduite de 33%... Mais le grand point fort du NH-C12P est sa hauteur inférieure à celle d’un NH-U9 moins efficace. Noctua a donc bien conçu son nouveau radiateur." (Pascal Thevenier, TT-Hardware.com) 01.04.2011 // BayReviews.com NH-C12P Review The cooler performed very well in all our tests and it beat the AMD stock and Evercool Transformer 4 coolers without any issues. Test verdict: "Overall, the Noctua NH-C12P is a smaller cooler which is also ultra-quiet and provides very good cooling. I would highly recommend this CPU cooler for anyone looking to replace their stock heatsink with something that can handle a lot more." (Vikram Chand, BayReviews.com) 22.09.2010 // Tech-Reviews.co.uk NH-C12P Review The Noctua NH-C12P has proven to be a worthy competitor. Knocking a good 21 degrees off of the load temperature of the stock cooler, the NH-C12P definitely gives you some extra overclocking headroom. When compared with the Gelid Silent Spirit the Noctua also manages to score slightly better temperatures than this cooler. Test verdict: "Overall the Noctua NH-C12P is a worthy replacement for your stock cooler. It’s not going to perform like a water-cooling setup or a more expensive cooler, but it’s an ideal choice for lower temperatures and more overclocking potential." (Rhys Sloman-Brown, Tech-Reviews.co.uk) 20.05.2010 // PCLabs.com.tr NH-C12P Review Peki hangisi? Aynı fiyata, eğer klasik kule tipi kasanız varsa -yani içine sığıyorsa- NH-U12P daha iyi soğutma performansı ya da alternatif olarak daha düşük gürültüye benzer soğutma performansı demek. Eğer HTPC tipi, yüksekliği kurtarmayacak bir kasaya sahipseniz ya da bu tip bir şeyler edinmeyi düşünüyorsanız NH-C12P. Test verdict: "Eğer bir HTPC tipi, ufak tefek bir kasaya soğutucu arıyorsanız aklınızda bulunması gereken bir seçenek. Özel sessiz fanı düşük devirde de iyi bir soğutma sağlamanın yanısıra sessiz olmasını istediğiniz HTPC tipi sisteminizde varlığını hissettirmeyecektir." (Haluk Sekendiz, PCLabs.com.tr) 25.12.2009 // Gamereactor.no NH-C12P Review Ved full load nådde den varmeste kjerne (#1) en temp på 59 grader, mens Gigabyte X fikk en temp på 76 grader på samme operasjon. Temperaturen på chipset er også viktig og denne var 38 grader med Noctua NH-C12P og 47 for Gigabyte X. Her er det altså snakk om 10 grader forskjell. Og det i et kabinett som er helt åpent. Her kvitter alle kjølere seg med varm luft fort! Ytelsen er enormt bra. Det er ikke mye mer å si. Viften spinner også med 1400 rpm hele tiden og den høres ikke i det hele tatt på det turtallet. Noctua sender med flere adaptere for å senke viftehastighet hvis man ønsker dette. På en mindre hissig CPU er nok dette et godt valg. Spesielt i et HTPC kabinett. Viften på Gigabyte X spant med et maksturtall på 2700 rpm ved full load og dette ble veldig plagsomt etterhvert. Test verdict: "Noctua NH-C12P er en meget god kjøler. Den har en passform som gjør den til en av de mest kompatible kjølerne på markedet i dag. Kjøleytelsen er fenomenal og det er en bra bundle som er med i esken. Kjølepasta, vifteadaptere og fester til de soklene som er aktive i dag. Utformingen gjør at den også kjøler chipset og RAM-brikker noe som bare gjør den enda et hakk bedre. Noctua befinner seg helt på topp av dagens kjølermarked og dette er et produkt som får de varmeste anbefalinger fra en hardwarenerd."

The Low-Noise-Adapter (L.N.A.) and Ultra-Low-Noise-Adapter (U.L.N.A.) reduce the speed of the fan to 1100 / 900 rpm: 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. 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. 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 email@example.com 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). 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. Does the cooler offer sufficient clearance for my RAM modules? The cooler offers sufficient clearance for modules of up to 40mm in height. RAM modules with higher heatspreaders can cause compatibility issues on mainboards where the heatsink extends over the RAM slots. Is the cooler compatible with socket AM2+ and AM3? Yes. As AM2, AM2+ and AM3 are mechanically identical, the cooler is compatible with all three sockets. Can I use Corsair Dominator RAM with the cooler? The cooler can extend over the RAM slots on some mainboards. While DDR2 Corsair Dominator don't fit underneath the cooler, DDR3 Corsair Dominator do fit when the removable top heatsink is taken off as shown below. 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. I can’t spread the thermal compound by turning the cooler as described in the manual! Due to the new LGA mounting bars with screw threads that facilitate the installation process, there's little room to turn the cooler as described in step 4 of the supplied manual. There's nothing to worry about though, as you can still turn the cooler by a few millimetres in order to help the thermal compound spread. We've also made the compound slightly less viscous so that the contact pressure of mounting system is wholly sufficient to spread it. How much clearance for RAM or chipset coolers does the NH-C12P provide? The NH-C12P provides 44mm clearance for near-socket components: Does the cooler offer sufficient clearance for my RAM modules? The cooler offers sufficient clearance for modules of up to 40mm in height. RAM modules with higher heatspreaders can cause compatibility issues on mainboards where the heatsink extends over the RAM slots (Note that you can move the fan up as shown here in case only the fan hangs over the RAM slots). 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. Can I use Corsair Dominator RAM with the cooler? The cooler can extend over the RAM slots on some mainboards. While DDR2 Corsair Dominator don't fit underneath the cooler, DDR3 Corsair Dominator do fit when the removable top heatsink is taken off as shown below. Please also note that the NF-P12 fan can be moved upwards or taken off in order to improve RAM compatibility as shown here. 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. 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.

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 firstname.lastname@example.org.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.
