Noctua offers the best of all worlds with the NH-C14; great cooling of the CPU, additional cooling to the surrounding components, silence during even the most stressful use, and a bit of flexibility to go in larger cases. Test verdict: "I know this is a near $100 cooler, but if you want the best of cooling with the utmost in silence, look no further. The NH-C14 surprised me and is my new cooler to recommend to anyone who has room for this monster." (Chad Sebring, TweakTown.com) 26.12.2010 // SilentPCReview.com NH-C14 Review The C14 outperforms its smaller predecessor, the C12P, by about 4°C on average. This makes it easily the best down-blowing cooler we've tested, and on par with with many reputable tower models. With two fans it's propelled into elite status. While this isn't a fair apples-to-apples comparison, it's still an impressive display of prowess for top-downer. [...] The acoustics of the P14 are generally smooth, with most of the audible noise being in the form of air turbulence which of course is unavoidable. [...] The P14 is one of the best sounding 140 mm fans you can buy and the included adapters gives users the ability to undervolt easily. Test verdict: "Down-blowing heatsinks typically do not perform as well as their side-blowing brethren when it comes to CPU cooling, but the C14 bucks this trend. Perhaps more importantly, it possesses something that most high performance coolers do not: a diminutive stature. With a fan on top, it measures 130 mm tall, about 25~30 mm less than most large tower heatsinks, allowing it to fit into smaller cases. [...] The C14's three different fan configurations makes it the most versatile heatsink we've ever encountered [...] a versatile short top-down cooler that delivers excellent performance." (Lawrence Lee, SilentPCReview.com) 26.04.2011 // TechPowerUp.com NH-C14 Review Whoosh. The NH-C14 shatters the myth that top-flow coolers are fundamentally inferior to side-flow ones. Aside from being the best performing cooler thus far on our new cooler bench, the NH-C14 should be the best performing top-flow coolers out there in the market. The air flow of top flow coolers provides some cooling for components around the CPU area, and that is good for voltage-assisted overclocking. When overclocked, the CPU barely appears to be running hot, given that Bloomfield poses a very heavy thermal load. There should be a lot of overclocking headroom left. Test verdict: "I couldn't have imagined any other cooler manufacturer take up top-flow design at this market segment, and then go on to win big time in terms of performance. Not only is this top-flow cooler very much in the league of high-end side-flow tower-type coolers, but it can also compete with entry-level water-cooling in-a-box solutions. [...] Overall, the Noctua NH-C14 is wonderful piece of engineering. It's as if its designers wanted to do some mythbusting, and disprove that top-flow design coolers are passé." (B. Rajeev Raju, TechPowerUp.com) 06.04.2011 // OverclockersClub.com NH-C14 Review The Noctua NH-C14 is an improvement over the NH-C12 in both size and cooling capability. With this cooler you have the tried and true C style design from Noctua with an added twist. The addition of a second NF-P14 fan to assist the top mounted fan in moving airflow through the heat sink. When tested against the NH-C12P SE14 in the stock testing, it delivered slightly better cooling numbers in both the idle and load tests. Where the NH-C14 excels against it predecessor is when the thermal load increases. In the overclocked testing, the NH-C14 bested the NH-C12P SE14 by three degrees Celsius in the load testing. This result puts the NH-C14's cooling capabilities ahead of some of the all-in-one liquid and tower solutions in the comparison field. [...] Noise is just about always the enemy of a good air cooled heat sink. As proven in the past, this does not have to be so. Noctua engineers their cooling solution to be effective with their own low noise, high performance fans. This means that when the NF-P14 FLX fans are spinning at 1200+/- rpm they are pushing over 65CFM at 19.6 dBA. By using the "Low Noise" and "Ultra Low Noise" adapters, the fan speed as well as noise signature drops to an almost inaudible 13.2 and 10.1 dBA respectively. Couple the low noise generated by the fans and the rubber isolation mounts for both fans attached to the fin array and you have a very low noise solution with no vibration noise that can cause an irritation to the senses. Test verdict: "I did not think that a C style heat sink could stand up any better to the tower heat sinks or all-in-one liquid solutions on the market but Noctua again delivers a product that does the job of removing the thermal load while looking good and remaining dead silent." (Frank Dimmick, OverclockersClub.com) 18.03.2011 // Bjorn3D.com NH-C14 Review One may pause to think how it is possible that a heatsink shaped like a 'C' could possibly out the tower type coolers, but once again, Noctua is one step ahead with their innovation. The dual 140 mm fans blowing straight down at a whisper 1200 RPM are more than up for the challenge. This is one of the most impressive low-profile coolers we have ever encountered. Test verdict: "The Noctua surpassed expectations in performance, even outperforming the full tower-size coolers under full load by 4 degrees Celsius. The dual 140 mm fans and massive radiator in the uncommon 'C' shape makes for a smaller package for use in all types of cases, with a special nod to the HTPC users. Everything was of the highest quality, from the solder joints on the heat pipes to the flawless die." (Joe Gulczinski, Bjorn3D.com) 10.02.2011 // ThinkComputers.org NH-C14 Review Looking at the performance numbers this CPU cooler performs very well. At the stock speed of our CPU the NH-C14 had idle and load temperatures of 21C and 37C respectively. This is a 12C difference during idle and 16C during load, which is very impressive. Looking at the overclocked results it performed 9C better during idle and again 16C better during load. The performance really does speak for itself. Also the cooler is very quiet, especially considering it has the 2 large 140mm fans. Test verdict: "If you take into consideration the cooling performance, versatility, quality and quiet operation if you have the money the NH-C14 is worth every penny." (Bob Buskirk, ThinkComputers.org) 05.01.2011 // KitGuru.net NH-C14 Review The variety of mounting methods means this cooler is going to be accessible to a huge audience. With both fans installed it requires 130mm height, which is 30-40mm less than most high end tower coolers. If you remove the top fan, this height demand reduces to 105mm, meaning it is ideal for a performance oriented media center system build, even in compromised space. The cooler isn’t quite the powerhouse that the NH D14 brings to market, but the D14 is such a gargantuan cooler that it blocks memory slots and demands a lot of space inside a system. The C14 is a complimentary design that tackles a different, yet equally demanding market space. Test verdict: "We are very impressed with this cooler, the quailty is unquestionable and the cooling performance is stunning. Another masterpiece from the Austrian cooling company who are consistently redefining the term ‘high quality cooling’. KitGuru says: Ideal for a wide range of uses, and with two of the finest 14cm fans on the market." (Allan Campbell, KitGuru.net) 04.01.2011 // PC Update #51 NH-C14 Review Plusieurs montages sont possibles, avec deux ventilateurs en push/pull, avec un seul au-dessus, avec un seul en dessous, il y en a pour tous les scénarios ! Les performances avec deux ventilateurs sont excellentes. Pas autant que celles des doubles tours de l’article d’à côté, mais presque. Pour un ventirad qui reste sous les 130 mm, c’est énorme Test verdict: "Le C14 est une nouvelle bombe de Noctua, idéale pour de nombreux PC home cinéma." (Thomas Olivaux, PC Update) 21.12.2010 // BCCHardware.com NH-C14 Review At the end of the day the Noctua NH-C14 scored very well in our testing thanks to its good performance and low noise. The NH-C14 is a nice choice if you don't have much room inside your case and when compared to other "lower profile" coolers the NH-C14 is easily one of the best. Thanks to the performance and low noise the Noctua NH-C14 has earned our "Editor's Choice - Gold" award. If you are in the market for a low profile cooler make sure to give the Noctua NH-C14 some serious consideration. Test verdict: "This cooler is a great design and if space inside your case is an issue this might be one of the best performing coolers money can buy. Most heatpipe coolers available today are much taller than the Noctua NH-C14, but as we saw in our testing the NH-C14 was able to keep up with them (and remain nice and quiet in the process)." (Jason Schneider, BCCHardware.com) 21.12.2010 // AwardFabrik.de NH-C14 Review Zusammenfassend lässt sich festhalten, dass der Kühler selbst in schwierigen Situationen standhalten konnte. Bei einer CPU-Spannung von 1,25V bei unserem QX9770 und einer Lüfterspannung von 7V wurde gerade einmal eine Temperatur von 39°C erreich, mit einer Spannung von 12V nur sehr kühle 36°C. Damit setzt sich der Kühler an die Spitze und überholt selbst die Konkurrenz aus eigenem Hause. Bei einer Spannung von 1,35V auf der CPU kommt er bei 7V nicht mal auf 50°C, lediglich 45°C werden hier ermittelt. Ein sehr guter Wert, der auch mehr als genug Luft für OC als auch heiße Sommertage bietet. Bei 12V sinkt die Temperatur des Prozessors auf 43°C, damit liegt er ganz weit oben in der Rangliste. Nur ein Kühler ist ein Quäntchen stärken als der NH-C14, nämlich der NH-D14. Zu den ausgesprochen guten Testergebnissen der Temperatur gesellen sich die durchaus, auch für den Dauerbetrieb anwendbaren, Lautstärkemessungen, die mit maximal 41,9dB im verbauten Zustand auch noch im grünen Bereich liegen. Anzumerken sei noch, dass durch die gewählte Bauform auch umliegende Elemente, wie die Spannungswandler, die Northbrige als auch der Arbeitsspeicher optimal mit kühler Luft versorgt werden, sodass auch die Gesamttemperatur im Gehäuse sinken sollte. Test verdict: "Insgesamt bietet Noctua mit dem neuen Schöpfling NH-C14 einen äußerst leistungsstarken Kühler für Enthusiasten. Wer jetzt noch über den hohen Preis von knapp 75€ hinwegsehen kann, sollte unbedingt zuschlagen."

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. 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. 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. 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. 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 clips are almost touching my VGA card! On some mainboards, the fan clips may be very close to the rear side of VGA cards installed in the first PCI-E slot. Please insulate the fan clips using duct tape or shrink-on tubes in this case. 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. How much clearance for RAM or chipset coolers does the NH-C14 provide? The NH-C14 provides 38mm (Dual Fan Mode and Low Profile Mode) / 65mm (High Clearance Mode) clearance for near-socket components: 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. The fan clips are almost touching my VGA card! On some mainboards, the fan clips may be very close to the rear side of VGA cards installed in the first PCI-E slot. In this case, please install the cooler with the bendings of the heatpipe towards the graphics card in order to have more space. Alternatively, you can also insulate the fan clips using duct tape or shrink-on tubes. 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. 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. Can I use the NF-A15 fan on my Noctua CPU cooler? The NF-A15 is fully compatible with the NH-U12P, NH-C12P and NH-C12P SE14. On the NH-D14 and NH-C14, the NF-A15 fan can only be installed using optional fan clips. For this, please contact our customer service. 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. Should I take the cooler off before transporting my system? 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, for safety reasons, taking the cooler off. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the heatsink installed. 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 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. Note that this compatibility list indicates mechanical compatibility only and does not take into account whether or not the mainboard will be able to automatically control the speed of the cooler’s fans. Since many modern mainboards can only control 4-pin PWM fans and this cooler comes with 3-pin fans, the fans will usually run at full speed and you can use the supplied Low-Noise Adaptors to reduce the fan speed. 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.
