NF-B9 test

At our airflow test, Noctua's fan delivered maximum airflow compared to the other contestants. From several previous reviews, we have seen that Noctua specialises in making silent cooling products, and this is proved here, as the NF-B9 proved to perform without annoying the user.
Verdict du test: "The NF-B9 was the best performer during our tests, while being silent. We can easily say that this 92mm fan is totally worth the money considering the cooling performance it offers" (Nasioulis Evangelos, mega-labs.com)

NF-B9 test

Pagal gautus rezultatus matome, kad Noctua NF-B9, kad ir būdamas toks mažas ventiliatorius, vistiek sugeba padėti aušinti kompiuterį. Ramybės rėžime stulbinančių rezultatų neparodė. Temperatūra sumažėjo tik keletu laipsniu, bet apkrovus procesorių, jo temperatūra buvo net 5 laipsniais mažesnė negu be NF-B9. Tai labai geras rezultatas.
Verdict du test: "Taigi, kaip visada Noctua gaminiai parodo geriausius rezultatus, taip ir šis. Jeigu nėra galimybės pajungti didesnio aušintuvo, tai toks mažas taip pat padės atsikratyti šilumos. Ventiliatorius didelio garso neskleidžia, bet norint kad dar tyliau dirbtų galima panaudoti low noise adapterius, su kuriais taip pat kokybiškai aušinsis." (Marius Kavaliauskas, Techpill.lt)

NF-B9 test

Los datos fueron categóricos, Noctua tuvo un mejor desempeño y bajo considerablemente las temperaturas, al parecer sus aspas mejoradas dan una mejor presión estática y por ende un mejor flujo de aire.
Verdict du test: "En realidad determinamos que el desempeño de este ventilador es casi insuperable, ya que a esas RPM ningún ventilador te genera esa presión estática y por sobre todo a un nivel sonoro bastante bajo. Como dije anteriormente los datos fueron categóricos y hablan por si solos, Los ventiladores Noctua NF-P12 y NF-B9 fueron diseñados y especializados para lugares donde la pasada de aire es estrecha y aprobaron muy bien esta prueba, superando a sus pares de otras marcas" (Victor Parra, Hardmodding.net)

NF-B9 test

Incrementando la distanza tra le pale e il bordo interno del supporto perimetrale della ventola nelle zone più periferiche in cui la ventola raggiunge velocità maggiori, la particolare tecnica di smussamento delle pale della ventola aiuta a ridurre le interazioni critiche tra rotore e statore. Questo stratagemma consente di ridurre la rumorosità prodotta.
Verdict du test: "Le due ventole Noctua in esame ben si prestano ad essere collocate su dissipatori high-end per schede video, tra cui il Thermalright. Entrambi i prodotti sono caratterizzati da un'ottima qualità costruttiva ed impiegano materiali di prima scelta oltre a tecnologie proprietarie sviluppate ed implementate per garantire il massimo delle prestazioni."

NF-B9 test

Le temperature verranno monitorate in tre situazioni differenti: con dissipatore stock senza ventola (passivo), con ventola originale nVidia ed infine con la Noctua NF-B9. Come possiamo notare nel primo grafico le temperature rilevate con dissipatore completamente passivo sono davvero elevate, la situazione migliora anche se di poco aggiungendo la ventola originale, ma sostituendo quest'ultima con la Noctua, la situazione cambia sostanzialmente con un vantaggio di ben 12°C per il NorthBridge e 15°C per il SouthBridge. La situazione mettendo sotto stress il sistema non cambia di molto, infatti abbiamo un miglioramento delle temperature pari a 14°C per il NorthBridge e 17°C per il SouthBridge. Che dire, risultato stupefacente.
Verdict du test: "In conclusione possiamo ritenerci soddisfatti del prodotto inviatoci da Noctua, in quanto grazie alle sue innovazioni e al suo design è di sicuro tra le migliori 92mm in circolazione." (Alessio Vincenzo Cannavale, PCBrain.it)

NF-B9 test

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.
Verdict du test: "[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-B9 test

As expected the NF-B9 doesn’t beat its competitors (which are the best performing 120mm fans reviewed at Verdis Reviews). However, what is interesting is how small the margin is between the results. The NF-B9 despite being beaten is only done so by up to 1 degree in each instance which shows how well the fan has performed considering its size. Therefore, for a 92mm these results are really very encouraging and display how well the NF-B9 is at cooling. If compared to other 92mm fans I’m sure it would be somewhere near the top.
Verdict du test: "Once more Noctua have demonstrated their skill as a thermal solutions company and come up trumps. The technology that goes into the NF-B9’s construction is very thought out and combines to form a fine product with achieves great cooling and low noise outputs." (Joe Blackmore, VerdisReviews.com)

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.

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.

PWM PWM

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 can I check if my 4-pin fan header supports PWM?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.


If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.
