NH-C14 Review

Tower coolers will have the benefit of the potential for a bit lower temperatures than what the NH-C14 offers, but they don't take care of the motherboard as does this cooler. 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)

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)

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)

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."

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)

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)

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)

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)

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)."

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." (Denis Emmerich, AwardFabrik.de)

Installation Manual (PDF)

Information Sheet (PDF)

Is the high weight dangerous for the CPU or socket?

No. Noctua coolers possess an extremely reliable SecuFirm™ mounting system. Thanks to the screw connection with the backplate on the rear side of the motherboard, the exceedance of the weight recommendations by Intel and AMD common among high-end coolers is completely unobjectionable.

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.

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.

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.

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.


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.

1366 compatibility

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.

1366 compatibility

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:

C14 Measurements

C14 Measurements

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.

Asus X-socket

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.

Can 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.

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.

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
  1. the TDP limits are extended or disabled in the motherboards' BIOS.
  2. the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
  3. 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.
