## Overview

The Noctua NF-S12A PWM is a premium 120mm case fan designed for ultra-quiet, efficient cooling. Featuring advanced blade design with Anti-Stall Knobs and an Acoustic Optimization frame, it delivers up to 8% better airflow-to-noise ratio than its predecessor. Controlled via 4-pin PWM, it runs up to 1200 RPM with a max noise level of just 17.8 dB(A). Built with durable SSO2 bearings, it offers over 150,000 hours of reliable operation, making it the elite choice for professional-grade PC cooling.

## Description

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 Optimization) 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.

Review: Produto excelente.
Review: This is the king of quiet PC fans. I checked specs on a number of them, and none match this for both noise levels and airflow. It runs at a maximum of 1200 RPM, or can be limited to no more than 800 RPM using the provided low-noise adapter. Also provided is an extension cable, screws, and rubber mounting devices that can take the place of screws, providing a mounting system guaranteed not to have any vibration noise. All provided in a stylish book-like package, with a nicely laid out instruction manual. Performance is excellent. It's extremely quiet while still moving a good amount of air. It looks good too, if you're into that sort of thing. Makes a change from plain boring black or grey devices. Installation is easy enough using the screws provided. The rubber mounting devices are a bit trickier, especially if you're trying to install the fan in a cramped PC case and/or where you can't get full access. You need to pull them through the screw holes, and they are a tight fit, requiring them to be wiggled around to get them fully through the holes. This is OK if you can get full access to the holes, but can be very hard if you're trying to install it in a tight place. If you're trying to lower the noise of your PC fans, or any device that uses (or can use) a 12cm / 120mm fan, then I know of no fan better than this one. The only downside is the price. It's definitely priced for the enthusiast market, and is packaged as such: everything about it shouts quality, high-end product. That's fine, but I likely would have bought a couple more if I didn't have to keep paying for stuff I don't need. It's a shame that they don't offer a 'bare' version that doesn't include the accessory pack. While it's well put together, and will be appreciated in many installations, there are likely many users who, like me, only need the fan, and won't use the provided screws, rubber mounts, extension cable or low noise adapter (all of which can be bought separately if the buyer later changes their mind about needing them.) Noctua really should consider also making the fan available on its own so that users who don't need all the other stuff don't have to pay for accessories and packaging they really don't need. I suppose they prefer to be seen as a luxury brand, but that's definitely costing them a few extra sales, at least from me.

## Questions & Answers

**Q: Hi, should I get this or the Noctua NF-F12 for a case fan?   Thanks.**
A: If your fan location doesn't have any filters or obstructions then the S12a will be what you want, but if it does have any sort of filter, or resistance the fan has to pull through, you'll want an NF-P12.  Several reviews have remarked that in a resistance based location the P12 works just as well as the F12, and does so with less noise.  The F12 would only be better for high temp heatsinks with its higher RPM range.I personally own all 3 types and have an F12 on my CPU heatsink, 2 P12 fans as intakes that are behind a dust filter, and 1 S12a as a rear exhaust.  I previously used 2 S12as as the intakes but they were really loud behind the filters.

**Q: What is the difference between the PWM,  the ULN and the FLX versions?**
A: PWM is the most standard version. People who want to push a little extra air but still stay quiet and keep up with a mild overclock, these are also 4 pin.ULN is targeting users who hate sound. These are lower voltage and push less air.FLX is the dynamic fan, you can run it a little higher or lower watt and push a littler higher or lower air.Personally I can't see any reason to use anything but PWM. They even come with a free adapter to lower the voltage if for some insane reason this already super quiet fan isn't quiet enough.

**Q: What is the cfm at min and max rpms?**
A: For a given RPM there is a performance curve; Maximum CFM at minimum static pressure, minimum CFM at maximum static pressure and all the points in between.

**Q: Are these sealed bearing fans?**
A: From the Noctua FAQ: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.

Auch hier bekommt man wieder die von Noctua gewohnte hochwertige Qualität geliefert. Dank seinem hohen Durchsatz, dafür mit weniger statischem Druck, hat man hier einen Lüfter der sich hervoragend dafür eignet die warme CPU Luft aus dem Gehäuse zu schaufeln. Dank der PWM Regelung hat man hier auch einen sehr leisen Betrieb oder einen kleinen Orkan, wenn man voll aufdreht. Da ich die Asus Lüftersteuerung nutze, habe ich einen Bereich von etwa 620rpm (idle) bis 850rpm (Last bei etwa 55° CPU). In diesem Bereich ist der Lüfter praktisch nicht zu hören, schafft aber genug warme Luft hinaus. Wichtig ist lediglich das die Gitter vor oder hinter dem Lüfter großzügig dimensioniert sind. Falls die Gitter zu engmaschig sind, ist der NF-P12 die bessere Wahl. Das einzige was den Gesamteindruck etwas trübt, sind die Silikonstifte um den Lüfter zu montieren. Diese steckt man von außen durch das Gitter und setzt den Lüfter auf und zieht die Stifte durch die Löcher. Was bei einem Frontlüfter noch aktzeptabel ist, sofern man ihn beidseitig erreichen kann, ist beim Hecklüfter eine sehr fummelige Angelegenheit. Die hinteren beiden Stifte konnte ich nur mit einer Pinzette greifen und bis zur Rast ziehen. Hier macht es die Konkurrenz mit beidseitigen Stiften oder dem bequiet System deutlich besser. Fazit: Wenn der Lüfter erstmal montiert ist, hat man einen zuverlässigen, leistungsfähigen und leisen Gehäuselüfter.
