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

Noctua is well known for being quiet, but also have good performance. They have definitely stayed true to their reputation. The Noctua NF-A series have exceptional build quality through and through. All of the fans performed well during the tests. On top of that, they were also quiet, especially if run at nominal speeds instead of their maximum.
Test verdict: "The Noctua NF-A Series is a comprehensive line up of fans that will be great addition to many system environments." (Ben Joubert, APHNetworks.com)

NA-FC1 Review

Wszystkie wentylatory oraz akcesoria są godne polecenia. Noctua ponownie pokazuje, że umie zrobić świetne konstrukcje. Śmigła są wydajne i prezentują się dobrze pod względem kultury pracy. Także jakość wykonania stoi na najwyższym poziomie. Podobnie jest z akcesoriami – świetne wykonanie i odpowiednie działanie.
Test verdict: "W zakupie sprzętu przeszkadzać może jedynie cena, która jest spora. Jednakże znakomite produkty nie mogą być tanie bo było by zbyt pięknie." (Michał Andruszkiewicz, WhatNext.pl)

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)

NA-FC1 Review

Veliki NF-A20 i u PWM i U FLX verziji košta oko 33 € što je korektna cijena za veličinu ventilatora, svu opremu koju donosi i na kraju krajeva vrlo dobre performanse uz ne previsoku buku. Kvaliteta izrade je visoka, materijali odlični a tehnologije jamče dugovječnost – kao i šest godišnje jamstvo uostalom. NF-A12x15 su po cijeni od 24 € pogodni za ugradnju u skučenija HTPC kućišta i na manje hladnjake, a obavezno ih se treba malo usporiti jer su na visokim okretajima čujniji. “Propuh” koji stvaraju je vrlo dobar i na nižim okretajima. A4x20 je u svim verzijama oko 20 €. Visoka je to cijena za 40-milimetarske ventilatore, no zbog kvalitete izrade, jamstva i ponajprije velike kompatibilnosti i mogućnosti prilagodbe isplati se platiti i tako visoki iznos. Ventilatori jesu bučniji pri visokim okretajima, no za kakav komad mrežne opreme koji je u ormaru to i nije bitno, a koncentrirana je zračna struja visoka i moćna. NA-SAV3 i SAV4 su po 11.50 € za što kupac dobiva kvalitetu, kompatibilnost s velikim brojem ventilatora i 16 komada nosača za po četiri ventilatora. NA-FC1 je svestran i kvalitetan kontroler za do tri ventilatora koji je moguće napajati direktno iz SATA Power konektora, pa može kontrolirati i jače ventilatore, no nije jeftin – 15 €. I za kraj, NA-SAC5 adapter koji može biti iznimno koristan za jače ventilatore koji se direktno napajaju iz SATA Power konektora i tako ne opterećuju ploču. Negativna je jedino cijena od oko 8 €.
Test verdict: "Noctua koristi svoju veliku ekspertizu u izradi sve boljih ventilatora iz godine u godinu. Novosti za ovu su tri varijante koje smo u ovom članku pokazali i svaka je od njih posebna, a to uključuje i sve izvedenice pojedinih ventilatora. [...] Svi Noctuini proizvodi su kao uvijek korisni i zaslužuju visoke preporuke, a jedino što ima zapravo možemo zamjeriti je nešto viša cijena za naše hrvatske (prazne) džepove."

NA-FC1 Review

Рассмотренные новинки Noctua – это то, чего многие ждали. Можно сказать это “празднество размеров”. Конечно, это не мейстрим-модели, и врядли получат широкое распространение, но они рынку были очень нужны. Да этого момента на рынке не было качественных 200 мм моделей вентиляторов, не было тонких 120 мм моделей. Новые Noctua A-серии – модели фактически уникальные, и их, по сути, даже сравнивать не с чем. Нет в этой нише конкурентов. Пока. Тестирование вентиляторов – дело совсем неблагодарное, и крайне требовательное оснастке. Особенно все это важно при рассмотрении вентиляторов, у которых заявленный уровень шума 24 дБА и ниже. При столь низком уровне шума шумометр работает плохо. Просто не улавливает разницы. Именно поэтому данный материал скорее не полноценный обзор, а ознакомление.
Test verdict: "Главное достоинство вентиляторов Noctua A-серии – уникальные размеры. За это можно простить все. Хотя и прощать то здесь нечего. Раздел “минусы” на этот раз пустой. Здесь все классно." (Oleg Ubeiko, OCClub.ru)

NA-FC1 Review

Сам по себе контроллер очень компактный. Управлять вентиляторами с его помощью чрезвычайно просто. На лицевой стороне реализовано два светодиода, регулятор оборотов и кнопка режима, именующегося как “No stop”. Данный режим полезен тем, что он не даст вентилятору полностью остановиться (ведь не все могут работать при напряжении от 5 В) – скорость будет поддерживаться на отметке 300 об/мин, благодаря чему BIOS материнской платы не будет демонстрировать ошибку работы вентилятора.
Test verdict: "Данный контроллер очень удобен в использовании. Он совместим с огромным количеством PWM вентиляторов от разных производителей, а также обладает возможностью подключения одновременно трёх вентиляторов. Стоимость порядка 1000 рублей вполне адекватна для подобного устройства с богатым комплектом поставки в виде полезных аксессуаров, которые будут задействованы в подавляющем большинстве случаев."
