NF-P14 FLX Review

Er ist gleichermaßen für Nutzer geeignet, die auf Kühlleistung angewiesen sind, wie auch für Silent-Liebhaber, denen die Temperatur zweitrangig ist. In beiden Fällen bietet er dabei eine sehr gute Leistung. Der Lieferumfang ist ebenso großartig: Mittels Adapter kann der speziell rund geformte Lüfter problemlos auf 120 mm- oder 140 mm- Vorrichtungen montiert werden, was den Einsatzbereich vergrößert.
Test verdict: "Eine abschließende Beurteilung fällt bei der gebotenen Leistung nicht schwer: Der Noctua NF-P14 FLX ist ein hervorragend verarbeiteter Lüfter, der keine Wünsche offen lässt." (Lukas Witt, TecCentral.de)

NF-P14 FLX Review

Les deux ventilateurs avaient sensiblement des résultats équivalents pour les tests accoustiques et cinétiques. L'anémométrie donne plus de différence. Le Noctua s'avère plus puissance avec des différences assez notables. Par exemple à 5V, le Noctua tourne 10 RPM de moins que le NanoXia mais offre un flux d'air plus élevé ! La technologie des pâles utilisée par Noctua semble donc faire son effet. Si on compare le rapport performances / bruit, à 5V les deux modèles sont au même niveau mais à mesure que la vitesse augmente, le Noctua domine avec un meilleur rapport et une meilleure pression statique.
Test verdict: "Noctua propose un monstre adaptable en emplacements 120 mm et offrant un excellent flux d'air via une technologie de pâles crantées efficace. Le silence est toujours au rendez-vous et le bundle aussi riche." (Mickaël Nicotera, RexWare.fr)

NF-P14 FLX Review

The Noctua NF-P14 FLX fans are a nice addition to the lineup of cooling products from Noctua. They offer better airflow at lower noise than Noctua's own NF-P12 fans. Granted, these fans don't have nearly the airflow that some other fans do, but they are super quiet - even at full speed. They mount on most 120mm fan mounts - whether it is your favorite heatsink or your case - and have metal adapters for 140mm mounting as well.
Test verdict: "In the end, these fans are easy to like. When priced around $20, they offer great value, low noise and good performance. If you need extra airflow in your case and you don't want to add a bunch of extra noise to your system, these are certainly a good choice." (Benjamin Heide, BCCHardware.com)

NF-P14 FLX Review

Si en Idle les écarts restent encore minimes, 3 °C maximun, en Burn le NF-P14 offre des performances remarquables. En 5 Volts, la température CPU est de 94,2 °C avec le SilentWings contre 79 °C ! Pour le Noctua. La carte mère et la carte graphique enregistrent une perte de 4° C toujours à l’avantage du Noctua. Les écarts sont toujours aussi importants en 7,9 et 12 Volts. Au niveau du GPU, ce sont respectivement 9 et 6 °C de différences contre 14,5 °C et 13,7 °C pour le CPU et 5 °C et 6 °C pour la carte mère.
Test verdict: "Que ce soit en 5, 7, 9 ou 12 Volts, le NF-P14 FLX offre les meilleurs résultats quelque soit le sous système considéré. [...] Noctua signe un produit de qualité, résolument haut de gamme qui dans le recherche de silence nous permettra de nous passer de plusieurs autre ventilateurs." (Jérôme Gianoli, GinjFo.com)

NF-P14 FLX Review

La ventola, come tutti i prodotti Noctua, è progettata e costruita con materiali di prim’ordine, la fattura è di alto livello così come il bundle che è completo e comprende tutto ciò che può essere necessario durante l’installazione. La flessibilità d’utilizzo è garantita dai due adattatori che sopperiscono alla mancancza del controller PWM, consentendo tre differenti velocità di rotazione e livelli di performance; inoltre grazie agli adattatori sarà possibile installare la ventola sia in fori da 120mm che da 140mm. Le emissioni acustiche, anche a velocità massima sono contenute ed il flusso d’aria generato è piuttosto elevato.
Test verdict: "La Noctua NF-P14 FLX rappresenta un’ottima scelta per coloro che vogliono dare una marcia in più al proprio dissipatore ad aria, o migliorare la ventilazione all’interno del case." (Rocco Eduardo Battista, HWMaster.com)

NF-P14 FLX Review

Coming in, I expected a certain level of quality and performance from these fans. I mean after all, they ARE Noctua fans. What I got in return is exactly what I wanted — fans that keep everything in my PC extremely cool without making a bunch of noise. In fact, I use all four fans without any of the Low Noise Adapters, and I can’t even hear them. All you can hear is the air rushing through the side panel, which happens to be a foot away from me, on my desk.
Test verdict: "These are not cheap fans, but you get what you pay for. Noctua fans only cool slightly better than any other cheap $10-15 fan, they just happen to give you that small increase in cooling, while dropping the dB level dramatically." (DJ Dixon, Go!GamingGiant)

Im Lieferumfang finden sich allerdings auch Adapter, um den Lochabstand auf das für die Lüfterbreite übliche Maß zu erhöhen, natürlich direkt per Gummi-Inlay entkoppelt. Echte Entkoppler finden sich ebenso wie Lüfterschrauben, ein Low-Noise und Ultra-Low-Noise-Adapter für die Drehzahlreduzierung auf 900 bzw. 750 U/Min in der Verpackung. Der übliche Adapter auf 4-Pin Molex liegt ebenfalls bei, was für kaum einen Anwendungszweck Wünsche offen lässt.
Test verdict: "Dezente Laufcharakteristik trifft gute Leistung sowie Spitzenwerte bei sehr niedrigen Drehzahlen. Die Ausstattung ist Noctua-typisch üppig - Entkoppler, Spannungsadapter -, der schmale Rahmen mit variablen Lochabständen macht den Lüfter flexibel. In der oberen Preisklasse trotz der recht hohen Anlaufspannung ein guter Kauf!" (Max Doll, Tech-Review.de)

NF-P14 FLX Review

Noctua has a true game winner in the NF-P14 FLX, the fan fits most cases on the market with its flexible 120mm / 140mm mounting system. It is a Fan worth the price of around 21.9 euros, as you get a quality fan that works great. As an intake fan the NF-P14 FLX rely shines, it is near silent up to about 1000 rpm when used as an intake fan, allowing allot of air to be bushed into the case.
Test verdict: "No matter if you are a gamer or studio musician in need of a bit more airflow in your PC case the NF-P14 FLX is a Great buy!!" (Jesper Bosch, Dawfreak.se)

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.

Can I use the NF-P14 on my NH-U12 series cooler?

Yes, the NF-P14 can be used to further enhance the cooling performance of Noctua NH-U12 series heatsinks. Please consider the following points when using the NF-P14 on your Noctua heatsink though:

  1. The NF-P14 will sit on the spring-loaded mounting screw and thereby increase the overall height of the cooler (measured from the base) to 168mm (NH-U12, NH-U12F, NH-U12P, NH-U12P SE1366) or 163mm (NH-U12P SE2 or other models with NM-I3 kit). Please make sure that your case offers sufficient space!

    P14

  2. Please also note that the NF-P14 will sit on the small projections on the sides of the fins. You can prevent this by using spacers (e.g. rubber, silicone or felt pads).

    P14

  3. Due to the fan sitting on the projections or spacers, the fan clips will be very tight to put on. You can bend the clips in advance in order to make it easier to install them.

Can I use the NF-P14 on my NH-C12P cooler?

Yes, the NF-P14 can be used to further enhance the cooling performance of Noctua NH-C12P heatsinks. Please consider the following points when using the NF-P14 on your NH-C12P though:

  1. Please note that the NF-P14 will sit on the small projections on the sides of the fins. You can prevent this by using spacers (e.g. rubber, silicone or felt pads).

  2. Due to the fan sitting on the projections or spacers, the fan clips will be very tight to put on. You can bend the clips in advance in order to make it easier to install them.

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.

I get a CPU fan error despite the fan is running!

Some mainboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.

Can I disassemble my fan for cleaning?

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 paint my Noctua fan in order to change its color?

Since even small variations in the layer of paint can lead to an imbalance of the impeller, resulting in vibrations, higher noise levels, increased stress on the bearing and thus reduced lifespan, we do not recommend painting the fan. Please note that for the reasons stated above, painting the fan will void your warranty.

How can I find out the direction of airflow and sense of rotation?

When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise:

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.

What pin configuration do Noctua 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:
