NF-A14 FLX Review

Две модели Noctua серии NF-A14 демонстрируют отличные результаты. Оба вентилятора неплохо «дуют» уже при 25 дБ. Пожалуй, именно их можно назвать лучшими «корпусными» моделями в подборке.
Test verdict: "Подведем итоги сравнения 140 мм моделей. Звание лучшего корпусного вентилятора, пусть здесь и развернулась серьезная борьба, следует отдать Noctua NF-A14 FLX." (Константин Назаров, Overclockers.ru)

NF-A14 FLX Review

Schon bei der Verpackung macht Noctua seinem guten Namen alle Ehre und liefert den NF-A14 in einem wertigen Karton mit aufklappbarem Info-Deckel auf Vorder- und Rückseite. Zusätzlich wird der Inhalt durch eine doppelte transparente Blister-Schale geschützt. Die 7 Lüfterklingen im klassischen Noctua-Braun sitzen in einem hellbraunen Rahmen und das Ganze wird über ein Kabel in sehr wertigem schwarzen Sleeve mit Strom versorgt. Außerdem sind alle 8 Ecken mit abnehmbaren Gummi-Schützern entkoppelt. Beim Zubehör tut sich der Noctua-Lüfter besonders hervor. Neben 4 passend braunen Gummi-Mounts und 4 unlackierten Lüfterschrauben gibt es ein Verlängerungskabel, einen Adapter für Netzteil-Anschlüsse und zwei Drossel-Adapter. Alles selbstverständlich im selben hochwertigen Sleeve, wie das Lüfterkabel selbst. Da kommt keiner der getesteten Konkurrenten heran.
Test verdict: "Mit dem NF-A14 liefert Noctua einen durch sein Zubehör sehr vielseitigen Lüfter, der in allen Stufen gut dasteht. In allen Szenarien sind die drei Punkte dieses Lüfter im Diagramm weit rechts unten zu finden und dementsprechend gut ist es um seine Effizienz bestellt. Neben dem Thermaltake Riing bietet er in diesem Test das beste Verhältnis von Lautstärke und Luftdurchsatz." (Florian Weichselbaum, hardwareinside.de)

NF-A14 FLX Review

Noctuas NF-A14 FLX findet sich seit Langem unter den Top 3 im PCGH Einkaufsführer. Der ungewöhnlich gefärbte Lüfter zeigt seinen Premium- Anspruch nicht nur beim fürstlichen Preis und der aufwendigen Verpackung, deren Grundfläche bequem für ein 180-mm-Modell gereicht hätte. Auch das umfangreiche Zubehör und die lange Liste von technischen Innovationen vermitteln einen Oberklasse-Eindruck.
Test verdict: "Im Einsatz überzeugt Noctua durch eine geringe Lautstärke und eine angemessenen Kühlleistung, vor allem aber durch das eindeutig leiseste Lager im Test. Egal wie weit wir den Lüfter, unter Nutzung einer Lüftersteuerung mit Start-Boost, drosselten: Auch bei minimaler Luftbewegung können wir keine Nebengeräusche heraushören."

NF-A14 FLX Review

In questa recensione ci siamo realmente resi conto di quanto Noctua sia attenta ai dettagli e alla cura dei propri prodotti anche in delle “semplici” ventole che poi, in questo caso specifico, semplici non sono visto l’elevata cura nella produzione e nelle tecnologie adottate. Ci ha stupito moltissimo il fatto di ritrovare tutte le tecnologie citate nell’introduzione anche nelle ventole di dimensione ridotta come le NF-A4. Siamo decisamente soddisfatti sia dalle prestazioni in termini di efficienza/rumore, sia dal bundle che dai prezzi decisamente in linea con quelli di altri produttori ma assolutamente superiori in termini di caratteristiche e prestazioni. Attribuiamo a tutta la NF-A Series il premio Gold Award per l’innovazione tecnologica e la cura dei particolari che L’azienda ha dimostrato in questa serie di ventole super-efficienti.
Test verdict: "Ventole per ogni tipo di esigenza. Noctua con la serie NF-A ha pensato proprio a tutti e a tutto proponendo prodotti di altissima qualità e tecnologia mantenendo un ottimo rapporto qualità/prezzo. Decisamente apprezzata la cura dei dettagli e del bundle che rendoni queste ventole il TOP DI GAMMA sul mercato." (Davide Torno, QWERTYmag.it)

NF-A14 FLX Review

Sleeving dei cavi e dotazione bundle sempre fantastico, l’azienda Austriaca non si smentisce mai da questo punto di vista. Facile il montaggio con i gommini rapidi in dotazione e l’utilizzo con le prolunghe e gli adattatori presenti, inoltre tutte le ventole sono munite dei gommini anti-vibrazione a gli angoli. Le ventole da 140mm e 150mm sono più efficienti e silenziose delle comuni e quasi sempre usate da 120mm, infatti le Noctua in esame di comportano benissimo! Perfette, silenziose ed adatte ad ogni utilizzo. Le versioni PWM riescono a combinare in modo fantastico silenziosità e potenza dissipante, fanno il loro dovere in ogni situazione di utilizzo: nei case per creare il flusso d’aria, sul dissipatore per CPU e sui radiatori dell’impianto a liquido, insomma versatili ed affidabili.
Test verdict: "Qualità dei materiali superba (come sempre), Noctua rimane un punto di riferimento per le ventole. Abbiamo provato 4 modelli, 3 da 140mm ed 1 da 150mm, tutti fantastici" (Santoro Luigi, HWready.it)

NF-A14 FLX Review

Tras probar las serie NF-A de 140mm podemos decir que estamos ante cuatro grandes ventiladores, en general silenciosos y con un buen caudal aire. De la serie NF-A14 tenemos el modelo FLX que es silencioso y mueve un buen caudal de aire. El modelo ULN es el más silencioso de los analizados, es inaudible aunque su caudal no es excesivamente alto pero suficiente para refrigerar nuestra torre. El modelo PWM es silencioso eso si, a máximas revoluciones empieza a sonar algo más, moviendo un gran caudal de aire. De la serie NF-A15 el modelo PWM es el que más caudal mueve de los cuatro modelos analizados, a máximas rpm ya suena algo pero es normal debido al gran flujo de aire que genera. Concluimos que son ventiladores muy similares, cuyas diferencias son la velocidad de rotación. El modelo ULN está especialmente diseñado como ventilador auxiliar por su baja sonoridad. El modelo NF-A14 FLX destaca por ser silencioso y tener un buen rendimiento, pudiendo regularle las rpm mediante los adaptadores que incluye. El modelo NF-A14 PWM destaca por ofrecer un gran rendimiento regulando las rpm forma automática. Y el modelo NF-A15 PWN que tiene la particularidad de que dispone agujeros de montaje de 120mm, destacando su gran caudal de aire y sonoridad.
Test verdict: "No hace falta decir nada más, que hemos analizados unos grandes ventiladores muy versátiles, silenciosos y con un gran rendimiento, así que no podemos dejar de recomendarlos." (Jose Maria Martinez Perdigones, ActualidadHardware.com)

NF-A14 FLX Review

Comme d'habitude chez Noctua les nuisances sonores sont très basses, ils sont tous inaudibles à 5v et se font entendre à 12v, à part pour le ULN qui lui reste quasiment inaudible même à fond! Les ventilateurs produisent tous un son grave (comme tous ceux de la marque) qui n'est pas gênant et les moteurs sont dépourvus de bruits parasites, un très bon point.
Test verdict: "Nous voici arrivé au terme de ce test, que dire de ces Noctua NF-A14 ? On voit bien qu'ils sont de la même famille que les NF-S12A et continuent dans l'excellence, que ce soit au niveau des performances que dans le bundle en passant par un SAV au top et 6 ans de garantie. Vous ne pouvez pas vous tromper en optant pour un de ces ventilateurs" (Christian Marchini, Conseil Config)

NF-A14 FLX Review

It pushes a lot of air similar to its predecessor NF-P14 while maintaining very low noise. When placed in open space without any grills/resistance, there isn’t much noise to be heard. It’s so quiet that you do not need to chain with U.L.N.A or L.N.A. to reduce its speed. Most fans spinning above 1000RPM makes a lot of noise but this one is completely silent at 20cm distance. Noise: Quieter compared to NF-P14 while maintaining same performance when placed in between 2 tower radiators such as Noctua NH-D14. NF-P14 generated 47 db(A) whereas NF-A14 FLX generated 42 db(A) at 10 cm distance from my sound meter while they are sandwiched in between a NH-D14 Tower CPU Heatsink. This method basically tests both push and pull of the fan’s capability.
Test verdict: "Noctua fans are highly recommended as its able to deliver high performance airflow and low noise while consuming very little electricity. Backed with a 6 years warranty, its a no brainer to purchase this fan for your case." (Chan Chee Gene, Ayumilove PC)

NF-A14 FLX Review

Pozostaje więc pytanie, czy mogę polecić zakup recenzowanych "śmigieł". Dla pewnej grupy odbiorców na pewno będzie to bardzo dobra opcja. Wykonanie nie pozostawia żadnych złudzeń, to produkt najwyżej klasy i nie oszczędzano tutaj na materiałach. Nie muszę chyba wspominać o świetnym wsparciu technicznym ze strony producet i 6-letniej gwarancji. Należy zatem pamiętać, że płacąc te 80 - 85 zł, nie płącimy tylko za sam produkt, ale też za całą otoczkę w postaci właśnie supportu, który nie zawodzi.
Test verdict: "Nie jest to zatem sprzęt dla każdego, bo nie wszyscy wymagają tak wiele, jednak myślę, że zasługuje na moją rekomendację." (Wojtek Braś, infoBIT.pl)

NF-A14 FLX Review

Noctua nedávno obohatila svou nabídku ventilátorů o zbrusu nové modely, z nichž si dnes pomocí nové metodiky zkoumající průtok vzduchu i jeho rozptyl vyzkoušíme 120, 140 i 150mm verze. Postavit je budeme moci proti starším verzím i vybrané konkurenci.
Test verdict: "Provedení všech nových ventilátorů Noctua je na velmi vysoké úrovni, což platí i pro dodávané příslušenství a detaily jako gumové podložky v rozích, které mají tlumit vibrace." (Jan Vítek, SvětHardware.cz)
