Greater than one weekThese fans are *so* much quieter than my stock case fans. I recently upgraded my case with a bunch of these and an H80i. My Asus fan controller software keeps the RPM of these fans really low (mostly off) except during gaming sessions.

Greater than one weekcè poco da aggiungere agli altri commenti positivi. è una ventola pwm con connettore 4 pin da piazzare nel pannello frontale del cabinet per raffreddare il cestello degli hard disk o nel retro del cabinet per estrarre laria calda. ha poca pressione statica e quindi produce un flusso daria che non riesce a contrastare efficacemente le lamelle del dissipatore della cpu. a differenza di una normale ventola tachimetrica con connettore 3 pin che gira a velocità costante in base alle impostazioni del bios della scheda madre, la ventola pwm con connettore 4 pin ha un regime di rotazione che varia automaticamente al variare della temperatura desercizio del chip (cpu o gpu) perchè è dotata di un apposito controller allinterno del proprio motore che riceve informazioni tramite un quarto filo (che si aggiunge ai due di alimentazione e a quello tachimetrico) direttamente dalla scheda madre o dalla scheda video. la dotazione di serie di queste nuove ventole pwm della noctua è completissima. simpatico il doppino 4 pin e utilissima la prolunga 4 pin. se lalimentatore del pc è vecchio o poco efficiente, diventa utilissimo anche il cavetto l.n.a. per diminuire il voltaggio e quindi la velocità e il rumore della ventola.

> 3 dayI know the fan is working. My motherboard monitor shows the RPM of the fan. I cant hear it at all though, and I dont feel much air coming from it.

> 3 daynon compatible en PWM comme cest indiqué. je voulais le mettre en remplacement de mon ventilateur dorigine sur mon ASUSTOR. malheureusement échec :(

> 3 dayThis fan does not have very high static pressure so I would only recommend using it as an exhaust fan, and not an intake fan that has to pull through a hard drive or constricted grills. The noise dampening rubber mounts are a little tricky to put on, and one tip is they are very durable so you can pull on them quite hard to stretch them.

> 3 dayNot disappointed. Ive been building PCs for over 20 years and these are by far the nicest fans I have ever installed. They are ugly IMO but if you can get over the color combo you will not regret purchasing these fans. They are packaged better than any other fan and they are dead quiet. Highly recommend!

The NF-S12A marks the third generation of Noctua’s signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
SSO2 bearingThe NF-S12A features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Inner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. |
Scope of delivery
|
Anti-Stall Knobs
The NF-S12A"s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan"s stall margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.
