Product discontinued. Successor model: NF-A8 FLX

Sound-optimised blade geometry and profile: The NF-R8 is the first fan employing a novel 80mm rotor which was developed by the Austrian Institute for Heat-Transmission and Fan Technology (Österreichisches Institut für Wärmeübertragung und Ventilatorentechnik, ÖIWV). Thanks to the special optimisation of the blade geometry towards ultra low noise application, the NF-R8 is up to 10% more quiet than current high-end fans at the same flow rate.

Self-stabilising oil-pressure bearing (SSO bearing): The NF-R8 series are equipped with a magnetically centred, self lubricating oil-pressure bearing that provides a new level of quietness and long-term stability.

NF-R8 Review

Nous avons ensuite calcule I'efficacite reelle de ces differents ventilateurs en ramenant le debit d'air ä une frequence de rotation identique pour tous, ä savoir 1000 tr/min. Ceci permet de connaitre les performances concretes des differents modeles en fonction de I'aerodynamisme des pales. Contrairement aux 120 mm, cette efficacite a toutefois nettement moins d'importance sur les 80 mm : plus le ventilateur est petit, moins la structure des pales influe sur le debit. Malgre tout, on retrouve Noctua qui caracole en tete, preuve que sa reputation n'est pas forcement usurpee.
Test verdict: "Certes, le prix est alors tres nettement plus eleve, mais l'efficacite de ces deux ventilateurs est de tout premier plan, et cela, quelle que soit la plage de tension. Toutefois, le Noctua R8 disposant d'une courbe plus lineaire, c'est celui-ci que nous vous recommandons." (Samuel Demeulemeester, Canard PC Hardware 01/2012)

NF-R8 Review

Paleidus šį Noctua ventiliatorių stebuklas neįvyksta – vėjelio sukeliamas garsas girdimas net ir esant mažiausioms apsukoms, tačiau tik tyloje, prikišus ausį prie propelerio, o svarbiausia, guolių sukeliama vibracija yra „minkštesnė“ ir mažiau girdima negu Papst 8412 N/2GM.
Test verdict: "Valio! Noctua neapsimelavo ir iš tikrųjų pademonstravo nors ir nedidelį, tačiau juntamą privalumą prieš ilgametį ventiliatorių ir elektrinių motorų ekspertą Papst. Taip, aš pasilieku šį ventiliatorių ir montuoju vietoj garsiau veikiančio 8412 N/2GM!" (Tomas Jankus, TechXpert.lt)

NF-R8 Review

As for quality the blades can’t be easily bend and their shape allows for a very good airflow. About the noise, well i had my ear 10cm away and i could hardly hear it so i think that Noctua managed to create what is perhaps the best fan line in the market.
Test verdict: "[I]f you want the best when it comes to low noise, high built quality. excellent package and bundle then the Noctua line is the one." (Nik Kastrantas, RealWorldLabs.com)

NF-R8 Review

Der Noctua NF-R8 kann nicht nur als CPU Kühler dienen. Durch seine einzigartige Laufruhe kann er auch problemlos als Gehäuselüfter seine Arbeit tun. Unser Fazit : Der Noctua NF-R8 brachte uns ins Staunen. Wir hätten nicht gedacht, dass es noch 80mm Lüfter gibt, die so leise ihren Dient verrichten. Noctua beweist, dass es sie noch gibt.
Test verdict: "Für Silent PC User ist dieser Lüfter bestens geeigent. Nicht nur als Gehäuselüfter, sondern auch als CPU Kühler." (Norman Kaiser, Review-Base.de)

NF-R8 Review

Evidently, Noctua have done it again and easily outperformed a capable rival by over a degree in most instances. The only slightly tighter results are the system temperatures at load where only 0.4 of a degree separates the fans, but apart from this all the other readings are very impressive.
Test verdict: "Another superb product from Noctua that follows in the footsteps of the two fans that were reviewed previously: very high cooling potential and low noise emissions." (Joe Blackmore, VerdisReviews.com)

NF-R8 Review

Auch im normalen Betrieb ist der Lüfter angenehm laufruhig und sorgt mit seinen rund 1800 RPM für eine ordentliche Leistung. Der Low-Noise Adapter ist hier offensichtlich die beste Wahl für diejenigen die einen Ausgleich zwischen Leistung und Lautstärke haben möchte. Nebengeräusche oder Ähnliches sind bei dem R8 in keiner der Betriebsarten zu hören. Die Regelung mit den beiliegenden Adaptern ist sehr gut durchdacht, da hier keine Kabel vertauscht werden müssen, um den Lüfter leiser zu kriegen.
Test verdict: "Auch der letzte Lüfter aus dem Hause Noctua den wir testen durften hat auf ganzer Linie überzeugt. Vom Lieferumfang bis hin zum Betrieb kann der NF-R8 seine stärken durch ein spezielles Lager und den beiliegenden Stromadaptern ausspielen. Die Montage ist relativ einfach und auch die Leistung im Verhältnis zur Lautstärke sind durchaus positiv und als sehr gut zu bewerten." (Marcel Hinz, Moddingbase.de)

Information Sheet (PDF)

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.

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.

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 should I clean my Noctua fan?

Fans inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fans regularly 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.
In order to ensure flawless operation over many years of usage, Noctua’s premium grade SSO bearings are fully sealed to prevent the entering of fine dust particles. Please 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.

Can I disassemble my fan for cleaning (or other purposes, e.g. painting)?

In order to ensure flawless operation over many years of usage, all Noctua fans come with a premium grade SSO bearing, which is fully sealed to prevent the entering of fine dust particles. Please 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.

It is thus recommended to clean your fans 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 don’t use a vacuum cleaner as this may apply excessive force to the fan.

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.


What pin configuration do Noctua 12V fans use?

All Noctua fans feature the standard pin-configurations set out in the Intel and AMD specifications. These standard pin-configurations are used on most mainboards and fan controllers today:

Can I use Noctua fans in my system from Acer, Apple, Dell, HP, Lenovo or other major brands?

Noctua 12V fans comply with the established specifications for standard PC systems issued by Intel and AMD. Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often deviate from these specifications e.g. by using proprietary fan headers, custom pin-alignments or pin-configurations, different methods of fan speed control, etc. This can lead to compatibility issues when using Noctua fans in systems from said brands. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues (e.g. errors or shutdowns due to low fan speed) can often not be resolved. As a result, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.

Can Noctua fans be used to replace noisy stock fans in NAS devices?

Noctua fans such as the 40, 60, 80 or 92mm NF-A series models are ideal for replacing noisy stock fans in NAS devices in order to make them quieter and thousands of users have managed to significantly reduce the noise levels of their NAS units this way. However, while it is easy and straightforward to replace the fans in some cases, it can be very difficult in others, so Noctua strongly recommends that users carefully research if it is possible to easily replace the fan(s) of their NAS device before purchasing a Noctua fan for this purpose. Some of the common issues that can occur when replacing NAS fans are:

  • Different pin assignment: Whereas Noctua fans use the standardised pin assignment for PC fans (see this FAQ for details), some NAS units use different assignments. For example, some devices have the power and GND or rpm and PWM pins swapped. Therefore please carefully verify that your NAS device uses the same pin assignment as standard fans. Experienced users may also change the pin assignment by cutting and resoldering the fan cables, but please note that this will void your Noctua manufacturer’s warranty.
  • Different pin functions: Noctua fans use the standardised pin functions for PC fans (see this FAQ for details); however, some NAS units use fans where certain pins serve a different function. For example, some devices use the RPM pin for “power good” signals. Therefore please carefully verify that your NAS device uses the same pin functions.
  • Firmware speed control: Some NAS devices demand a certain maximum or minimum fan speed. If the new fan doesn’t have the same or similar maximum or minimum speed, the device may display errors or even shut down.
  • Different starting voltage: Most NAS devices use voltage-based speed control. If the new fan has a higher starting voltage than the original fan, it may not start up right away. This may lead the NAS device to display errors or even shut down because it suspects a fan failure.
  • Different power draw: Some NAS devices monitor the fan’s power draw. If the new fan has a lower power consumption than the stock fan, the device might display errors or even shut down.

Please note that most NAS manufacturers don’t provide detailed documentation regarding fan compatibility and control, so users who want to replace the fans of their devices usually have to rely on “How to” guides, blog and forum posts or video tutorials. For example, there are excellent video tutorials available for changing the fans in popular Synology NAS models (DS416j, DS1515+ and DS1812+ in English, DS416/DS415/DS916/DS216/DS214 and DS1515+ in German). Please also note that fan compatibility and control can vary from model to model and even from revision to revision even if the devices stem from the same manufacturer. As a result, it is important to make sure that the information or guidelines you rely on when replacing your NAS fan are applicable to your specific model as well as your specific hardware and firmware revision.

Due to the possible issues listed above, Noctua recommends that only experienced users attempt to replace their NAS fans. Please note that since there are so many different NAS models and most of them lack documentation for aspects such as fan compatibility and control, Noctua customer support cannot assist you with compatibility issues when replacing NAS fans. Please contact your NAS manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and control.

Can I use Low-Noise Adaptors with y-cables / multiple fans?

Yes, Low-Noise Adaptors (L.N.A.s) can be used with y-cables, but please make sure to use one L.N.A. per fan and to place the L.N.A.s between the y-cable and the fans as shown below. Never use one L.N.A. for two (or more fans) by placing it between the mainboard and the y-cable!
