The NA-FC1 is a compact, highly flexible controller for 4-pin PWM fans that can both work on its own for manual speed reduction and also work in tandem with the automatic motherboard fan control. By adjusting the NA-FC1’s speed control dial, users can either manually set a PWM duty cycle from 0 to 100% or reduce the PWM duty cycle supplied by PC motherboards in order to have the fans running slower than the automatic motherboard fan control would allow. While the brightness of the orange status LED provides visual feedback on the current dial setting, the push button allows the NA-FC1 to be switched into “no stop” mode, which prevents the fan from falling below a speed of 300rpm. Thanks to the supplied 3-way split cable and power supply adaptor, up to 3 fans can be controlled simultaneously.
Details
PWM based control

PWM based control

While most fan controllers are voltage based, the NA-FC1 uses the more sophisticated Pulse Width Modulation (PWM) technique that allows for more efficient control and lower minimum speeds, regardless of the fan’s starting voltage.
Manual control mode

Manual control mode

If the NA-FC1 doesn’t receive an input PWM signal from the motherboard, it works as a simple and efficient manual controller that allows the duty cycle to be set from 0 to 100%. This makes it ideal for manually slowing down high-speed PWM fans such as Noctua’s industrialPPC series in order to achieve consistently quiet operation.
Customising motherboard fan control

Customising motherboard fan control

Many motherboards provide insufficient options to customise automatic fan control or simply don’t go below certain duty cycles and speed levels. Using the NA-FC1, you can lower the motherboard’s PWM control curve in order to achieve truly silent operation, even with high-speed PWM fans such as Noctua’s industrialPPC series.
“No stop” mode

“No stop” mode

If the small push button is pressed and the green status LED is on, the NA-FC1 operates in “no stop” mode, which means that it will not allow the fan to fall below 300rpm, regardless of the speed setting and the input PWM duty cycle from the motherboard, thus avoiding BIOS fan errors.*
3-way splitter cable

3-way splitter cable

The supplied 3-way splitter cable allows the connection of up to three 4-pin PWM fans in order to control them simultaneously. Even more fans can be controlled at once when using additional NA-YC1 splitter cables that are supplied with many Noctua fans and available as an optional accessory kit (NA-SYC1).
Power supply adaptor

Power supply adaptor

As powering multiple higher wattage fans from a single motherboard fan header may damage the motherboard, the NA-FC1 includes an NA-AC4 adaptor that powers the device directly from the power supply unit while simultaneously receiving PWM input from the motherboard and forwarding RPM information. This makes it ideal for controlling multiple high-speed fans such as Noctua’s 3000rpm industrialPPC models.
6-year manufacturer’s warranty

6-year manufacturer’s warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all of them, the NA-FC1 fan controller is built to last and comes with a full 6-year manufacturer's warranty.
*Please note that many PWM fans have a minimum speed higher than 300rpm and as the function of “no stop” mode is to not let fans go below 300rpm, it is only useful for fans which are generally able to go below this speed. For example, a fan with 500rpm minimum speed will act the same with “no stop” mode on and off.

NA-FC1 Review

Wielu konkurentów nie daje wraz ze swoimi urządzeniami niezbędnych akcesoriów przez co jesteśmy narażeni na dodatkowe koszty. Tutaj ten problem nie występuje. Widać, że Noctua przez ponad 12 lat obecności na rynku wykonała wspaniałą pracę i udowodniła, że nawet najlepsze produkty można poprawić. Urządzenia z serii A wyróżniają się przede wszystkimi nowymi technologiami, niskim poziomem hałasu, wysokim przepływem powietrza i przede wszystkim świetnym wykonaniem. Modele A12x15 są ciche, solidne i mają tylko 15 mm grubości, za to A20 sprawdzą się w dużych obudowach, gdzie potrzebny jest duży przepływ powietrza. Małe modele A4x20 są przeznaczone głównie dla środowisk specjalistycznych, a dzięki adapterowi OmniJoin można je wszechstronnie wykorzystać.
Test verdict: "Powyższy artykuł powinien Was tylko utwierdzić w przekonaniu, że produkty austriackiej firmy są w rzeczywistości najwyższej jakości. Każdy z nich został świetnie zaprojektowany i dostarczany jest w bogatym zestawie." (Marcin Jankowski, pcfoster.pl)

NA-FC1 Review

Inoltre, abbiamo un cavo di prolunga e un cavo che consente di alimentare il controller tramite un cavo SATA. Il manuale fornito con il Noctua NA-FC1 è molto utile per comprendere le diverse modalità operative di questo dispositivo. Fuori dalla scatola, il Noctua NA-FC1 si presenta come un controller molto piccolo e compatto ma di qualità impeccabile di costruzione. Il potenziometro è molto liscio e senza gradini. In conclusione, questo controller è molto sobrio e pieno di funzioni, un ottimo prodotto come da sempre ci ha abituato la Noctua. Come costo, è un controller per ventole offerto ad un prezzo veramente molto basso, di controller per ventole ne ho visti e provati parecchi, ma questo in assoluto è tra quelli con il miglior rapporto tra qualità e prezzo che si possa trovare sul mercato.
Test verdict: "Controller per ventole della Noctua veramente molto consigliato." (TechUniverse.it)

NA-FC1 Review

Ceny za każdy produkt tej firmy są wysokie jednak idzie za tymi cenami jakość wykonania, przemyślana konstrukcja, solidność. Te cechy maja odzwierciedlenie wszędzie, w każdym detalu, nawet w szczegółach związanych z opakowaniem, ze sposobem zaciśnięcia termokurczek. Jedynie do czego mogę się przyczepić to kolorystyka (jedni chwalą jak ja, drudzy ganią) oraz cena.
Test verdict: "Długo myślałem nad podsumowaniem jednak opiszę to krótko – Noctua to Noctua. Dobrze wydane pieniądze." (Arkadiusz Byś, PCElite.pl)

NA-FC1 Review

Hoy hemos presenciado como Noctua lo ha vuelto a hacer, las prestaciones de sus nuevos productos continúan siendo la referencia que siempre han sido, pero hay otras cosas que también van a continuar. Frente a las grandes prestaciones tradicionales de Noctua hay otro aspecto que también se mantiene, este nivel de calidad no es barato, desde los 30€ que cuesta el ventilador de 200mm, el NF-A20. El adaptador SATA por 8€, el controlador por 20€ o los sorprendentes 15€ que cuesta el pequeño ventilador de 40mm, pasando por los más razonables 20€ por el ventilador más tradicional de 120mm. No obstante hemos de hacer hincapié en algo que solemos decir en Tecnogeekies bastante a menudo, aunque 20€ pueden parecer muchos, especialmente solo por un ventilador, su calidad y su durabilidad nos hacen recomendar esta marca siempre que vuestro presupuesto os lo permita.
Test verdict: "La calidad tiene un precio, pero en casos como el de Noctua merece la pena." (Ignacio Merino, Tecnogeekies.com)

NA-FC1 Review

+ ottima qualità costruttiva
+ cavetteria in dotazione sleevata e dall'ottima realizzazione
+ possibilità di regolare di fino il segnale PWM in arrivo alla ventola
+ led di stato
+ modalità "no stop" parecchio efficiente
+ in grado di reggere anche carichi elevati
+ saldature Pb free
Test verdict: "Passando al NA-FC1 qui Noctua ci ha piacevolmente sorpreso, il dispositivo risulta essere parecchio compatto, fatto bene con adattatori e cavetteria sleevata ma soprattutto funzionale; in tutte le varie fasi di test si è dimostrato essere un prodotto valido capace di regolare di fino il segnale PWM in arrivo dalla scheda madre - particolarmente utile per quegli utenti sprovvisti di curva di funzionamento o con step a gruppi di 10% o peggio 25%- ed in grado scovare e mantenere il minimo degli rpm di qualsiasi ventola PWM a prescindere dal segnale in arrivo."

NA-FC1 Review

We have no doubt about the top quality of Noctua products. Each one of them is well designed. Even the package is exceptional. Most manufacturers are missing these little things that count while Noctua provides package with everything you may need for installation. Long years of designing and engeneering gave great results. Where you could think there can’t be done much more, Noctua proved that even the best products can be improved. New A series fans are the best in their class and it’s hard to find anything similar on the market. Even though new fans are considered as “slim”, they provide top air pressure while keeping low level of generated noise. Perfect balance for all who expect the best from their fans.
Test verdict: "We are recommending all new Noctua products without any hesitation!" (Bartosz Waluk, FunkyKit.com)

NA-FC1 Review

Ventilátor (NF-A20) je naozaj "obrovský" a neskutočne kvalitne spracovaný. Keď ho chytíte do ruky, okamžite mu prepáčite jeho cenu 29.99 eur. Konštrukcia, príslušenstvo - všetko kričí na Vás top kvalitou. Na ventilátor som pozeral zopár minút než som sa vôbec dostal k testu.
Test verdict: "Noctua priniesla opäť skvelé produkty, ktoré nájdu svoje uplatnenie u veľa nadšencov do chladenia. Ak sa Vám zdá cena Noctua ventilátorov vysoká, môžem Vám s kľudom povedať, že za svoje peniaze dostanete top kvalitu a len málo ventilátorov sa vyrovná tomuto výrobcovi. Plus odo mňa dostáva Noctua za svoje ventilátory – 200mm, 120mm Slim a 40mm ventilátory, ktoré vynikajú pomerom výkon vs. hluk. Najväčší 200mm ventilátor si však zaslúži extra pozornosť, pretože vyčnieva nad hociktorý iný ventilátor, ktorý som doteraz videl a mal možnosť testovať. Na všetky ventilátory dostanete záruku 6 rokov. Regulátor NA-FC1 si pravdepodobne nenájde uplatnenie u bežných používateľov." (Lukáš Lancz, pc.sk)
