Successor to the award-winning NH-C14, the NH-C14S is an elite class top-flow CPU cooler that is extremely efficient, highly compatible and remarkably adjustable. Thanks to its deeper fin stack and the renowned NF-A14 PWM fan, the single fan NH-C14S provides similar quiet cooling performance to its dual fan predecessor while being even more versatile: With the fan installed on top of the fins, the cooler is compatible with RAM modules of up to 70mm height. With the fan installed underneath the fins, the total height of the cooler is only 115mm, making it suitable for use in many HTPC cases. At the same time, the new offset layout allows it to clear the top PCIe slot on most µATX and ATX motherboards. Topped off with the trusted, pro-grade SecuFirm2™ multi-socket mounting system, Noctua’s proven NT-H1 thermal compound and full 6 years manufacturer’s warranty, the NH-C14S is a premium quality top-flow solution for the highest demands.

Based on the award-winning NH-C14

Having received more than 200 awards and recommendations from leading international hardware websites and magazines, the NH-C14 has become an established reference for 140mm top-flow coolers. With its deeper fin stack and more efficient NF-A14 PWM fan, the new S-version provides similar performance and further improved compatibility.
C-Type top-flow design

C-Type top-flow design

The c-type top-flow design of the NH-C14S not only allows for superb quiet cooling performance while maintaining a much lower profile than today's 140mm tower-style coolers but also ensures excellent airflow over RAM modules and near-socket motherboard components.
Low Profile Mode

Low Profile Mode

Run with the NF-A14 fan installed underneath the fin stack, the NH-C14S stands only 115mm tall, which is much lower than tower coolers with 140mm or 120mm fans and allows it to fit many desktop style or HTPC cases.
High Clearance Mode

High Clearance Mode

Run with the NF-A14 fan installed on top, the NH-C14S provides extended clearance underneath the fin stack. This way, it is fully compatible with chipset coolers and RAM modules with heat-spreaders of up to 70mm height.
Offset design for PCIe clearance

Offset design for PCIe clearance

Compared to the original NH-C14, the layout of the NH-C14S has been offset in two axis. Thanks to this measure, the heatsink will clear the top PCIe slot on most µATX and ATX motherboards when the bendings of the heatpipes face the PCIe slots or the I/O panel.*
NF-A14 140mm premium fan

NH-C14S Review

While the performance of Noctua NH-C14S is not that impressive when compared to the NH-D15, let us remind you that the NH-C14S is a low-profile cooler made for HTPC or SFF PC builds. While it struggles to tame the Intel Core i7 5820K on LinX, actually the Noctua NH-C14S is still one of the best in its class. If you are in search of a good CPU cooler for your Intel LGA 115X or AMD AM4-based ITX or mATX rig, the Noctua NH-C14S offers great cooling in compact dimensions.
Test verdict: "The Noctua NH-C14S caters to enthusiasts with space constraints yet desire the best air cooling they can get in their small rigs with its good performance and silent operation." (Muhammad Firdaus, Pokde.net)

NH-C14S Review

The third cooler of our review, the Noctua NH-C14S, is virtually incomparable with the previous two coolers. It has over twice the mass of the other coolers and requires a much greater vertical clearance - at least 115 mm depending on configuration - instantly ruling it out as an option for the vast majority of HTPC cases and other narrow designs. If the fan were to be placed at the top of the cooler in order to increase the clearance of the RAM modules, it is unlikely that the NH-C14S will be compatible with any desktop or HTPC case, as it would not even fit inside designs that are meant for top-tier HTPCs. It is apparent that Noctua has designed the NH-C14S solely for users that are planning to build very high performance HTPC system with sizable cases and want a product that can compare to high performance tower coolers. Naturally, it cannot reach the performance of coolers such as the NH-D15 or the Cryorig R1 Ultimate, but it does get close enough to warrant excellent performance on any CPU currently available, overclocked or not.
Test verdict: "It is an expensive cooler but the quality and performance are well worth the money." (E. Fylladitakis, Anandtech.com)

NH-C14S Review

Очевидный плюс NH-C14S – универсальность. Комплектный вентилятор можно установить в нескольких позициях, в зависимости от возможностей корпуса. Также есть потенциал на дальнейший апгрейд. Докупить второй аналогичный вентилятор и все. Второй очевидный плюс NH-C14S – сама конструкция. Кулеры такого типа охлаждают не только процессор, но и околосокетное пространство. Если у материнской платы на самые крупные радиаторы на узле VRM, то дополнительный отвод тепла совсем не лишний. С хорошим разгоном практически обязателен. И напоследок еще о конструкции. Благодаря большому (в 2 мм) расстоянию между ребрами, охладитель эффективен даже при низких оборотах вентиляторов.
Test verdict: "Там можем ли мы рекомендовать к покупке Noctua NH-C14S? Однозначно ответ да. Это отличный качественный кулер, который принесет определенное удовольствие даже во время распаковки и установки. Более того, нельзя не отметить подход Noctua к клиентам. Если выйдет новый сокет, к которому требуются другие крепежные пластины, то Noctua бесплатно вышлет владельцу кулера новые скобы. Это, согласитесь, приятно." (Oleg Ubeiko, OCClub.ru)

NH-C14S Review

Noctua's NH-C14S is better in every way compared to the original NH-C14. Not only is it more efficient but it also performs much better while being much quieter. The additional heatpipe in the center of the heatsink and the improved NF-A14 fan make a noticeable difference in both cooling and noise performance.
Test verdict: "We strongly recommend the NH-C14S to anyone who's looking for a high quality top-flow design cooler that will give you fantastic cooling performance while providing high RAM and video card clearance." (Henry Peshkepija, RelaxedTech.com)

NH-C14S Review

Noctua liefert mit dem NH-C14S ein Gesamtpaket ab, welches in den Punkten Qualität und Silent-Tauglichkeit außergewöhnlich stark ist. Das im Gegensatz zum NH-D15 geringere Kampfgewicht zollt der Kühlleistung ihren Tribut und so muss der Top-Blow-Kühler seinen Hut vor den Platzhirschen aus der Doppelturmkühlerriege ziehen. Diesen Nachteil kann der NH-C14S aber beim Platzbedarf kompensieren, ohne dass die im Test verwendete und übertaktete Haswell-CPU überhitzte. So kann der kleine aber dennoch 820 Gramm schwere Kühler aus Österreich seine Stärken immer dann ausspielen, wenn die Gehäusebreite oder ein schwer realisierbarer Luftstrom im Gehäuse den Betrieb eines großen und leistungsstärkeren Turmkühlers verhindert.
Test verdict: "Bei unserem Test des NH-C14S glänzte der Kühler mit einer tadellosen Produktpräsentation und Verarbeitungsqualität mit der sich andere Kühlerhersteller messen müssen. Gepaart mit einem hohen Dynamikbereich des Lüfters erreicht das Produkt mit der markanten Farbgebung unsere Bestnote in Form des Hardware-Factory Gold-Awards. " (Thomas Radigk, Hardware-Factory.com)

NH-C14S Review

Au niveau performances, on fait comme pour le D15S, on va lancer un burn du CPU sous SiSoft Sandra, pour une durée de deux heures, températures enregistrées en fichier log au début, après 1h et a la fin. Une fois avec le ventilateur réglé en auto via SpeedFan et une seconde fois, ventilateur bloqué à 100%. Une fois de plus, on peut constater que Noctua tient ses promesses ! Avec une température maximale relevée de 45°c au bout de deux heures de burn et dans boîtier aussi petit, c’est vraiment pas mal du tout ! Il est toutefois vrai qu’avec un CPU au TDP de seulement 55W, la tâche n’était pas ardue, mais au vu du peu de flux d’air possible dans le boîtier, nous n’en n’espérions pas tant !
Test verdict: "Noctua signe la encore une belle réussite ! Un processeur « relativement » peu encombrant, adapté aux configurations les plus petites (ITX y compris) pour des performances qui n’ont pas à pâlir face aux concurrents !" (Damien Chevalier, MacFay Hardware)

NH-C14S Review

През последните няколко години компанията Noctua създаде много сериозно име в IT средите, особено когато става дума за охладители за процесори, или пък вентилатори за монтаж в компютърните шасита. Макар конкуренцията винаги да е била много сериозна, а понякога и доста добре ценово ориентирана, с високото ниво на качество на своите предложения, Noctua съумяха да се позиционират в най-високите нива на производители на споменатите компютърни продукти. Едва ли са много хората, които не са чували за вездесъщият процесорен охладител Noctua NH-D14, който междувпрочем съвсем скоро ще е напълно съвместим с процесорите на AMD с архитектура Zen и Socket AM4, благодарение на новите крепежни елементи, които от Noctua ще раздават (за пореден път) безплатно на всеки потребител, който може чрез документ да докаже, че притежава дънна платка и процесор за Socket AM4, както и разбира се охладител Noctua. Но да не се разсейваме излишно, ами да обърнем внимание конкретно на фокуса на този материал – процесорите Skylake и тяхното охлаждане.
Test verdict: "Noctua е един от най-сериозните и постоянните производители на процесорни охладители, които присъстват на компютърният пазар и година след година радват своите потребители не само с нови модели охладители, но и с някои специфични “бонус програми”, като например безплатни монтажни елементи за поставяне на по-стари модели охладители върху нови процесорни платформи."

Installation Manual (PDF)

Information Sheet (PDF)

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.


How big is the NH-C14S and how much clearance does it provide for RAM and mainboard heatsinks?

Please refer to the following drawing for the exact measurements and clearance for RAM and motherboard heatsinks:


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.
