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
Noctua probably makes the most advanced case fans in the market, with unique features and specifications that outperform any other fan.NF-R8 fan is an 8cm fan, that has high performance and low noise combined with the high quality Noctua always offers.
|
||||||
|
Test verdict: "Noctua as always made a high quality products that exceeds even the highest expectations.NF-R8 fan is a fusion of high airflow and low noise that can satisfy virtually anyone especially at the 8cm range case fans where noise levels are much higher than 9 and 12cm and users demand lower noise while maintaining high airflow."

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.

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)

Can I use Noctua fans in my system from Acer, Apple, Dell, HP, Lenovo or other major brands?
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!
How should I clean my Noctua fan?
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.
What pin configuration do Noctua 12V fans use?
Can I disassemble my fan for cleaning (or other purposes, e.g. painting)?
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 Noctua fans be used to replace noisy stock fans in NAS devices?
Noctua fans such as the 40, 60, 80, 92 or 120mm 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 Noctua fans be used to replace noisy stock fans in switches, routers or other network devices?
