Succeeding the vastly successful NF-S12, the NF-S12B is a next generation quiet fan featuring Noctua's advanced SCD2 technology as well as a highly optimised blade geometry with Bevelled Blade Tips that improves its award-winning predecessor's airflow efficiency by up to 10%. Topped off with Noctua's time-tested SSO-Bearing, 6 years warranty and versatile 1200/900/600 rpm speed settings, the NF-S12B FLX is a premium quality fan that offers full flexibility in quiet to ultra-quiet case cooling.

flx 3 speed settings for full flexibility
Providing 1200, 900 and 600 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the FLX (Flexibility) version can be fine-tuned for superior airflow or maximum quietness.

SCD Smooth Commutation Drive 2

Comment: OC Mod Shop review: The Noctua NF-S12B FLX is a well-built fan with a lot of innovation and thought behind it. It is on the pricier side, but these are also the Ferrarris in the case fan world

Comment: Complete review with nicely detailed technical info. HardwareBistro concludes that the NF-S12B is well made, quiet and efficient.

Comment: This site reviews the question you're asking. How does this fan compare to the Noctua NF-P12. Quite interesting.

I bought this fan to replace an Antec case fan that went dead. I couldn't beleive how quiet it was and when I first turned on my computer with the fan installed. I could barely hear it. I would definately buy this fan again when needed. (Read More)

I picked up two of the NF-S12B fans to replace two Coolermaster R4-L2R-20AC that barely lasted six months before they both started making noise.(Cheaper is not always better) Different blade configuration than the NF-P12 but they seem to work quite well as intake case fans. I am going to replace the exhaust fans as well on my case the next time these go on sale. (Read More)

Picked up these fans for my FT03 case as intake/exhaust. They works as good as the stock fans and do so with much less noise.

Bought for $9.99 on weekend sale about 6 months backs. Still working great. Tough to justify the $19.99 normal price though. Using in Antec 1200 case removed the dual 120 exhaust fans and replace with just a single of this fan temps are just as good. The accessories very useful. Needed to undervolt another fan where the MB couldn't used the Low voltage adapter worked perfectly. (Read More)

The only downside to these fans is that price. They do an amazing job cooling and make so little noise that it doesn't upset me. I would highly recommend these if price is not an issue. (Read More)

Overall I must admit I was plesantly surprised with this fan. I'm using this as an exhaust cooler on the rear of my case, since this fan is designed for 'open air' cooling, and not 'restrictive flow' cooling like in a CPU cooler. (If you want that, get the NF-P12-1300 instead.) I replaced a SilentX fan that had siezed after only a few years of use.

These are excellent fans. In fact, the best I've ever had. I have used CoolerMaster noisy LEDy fans with lights and noise. Do yourself a favor and buy real fans. Buy Noctua fans. (Read More)

A high quality case fan, that is a cut above the rest. This should suit just about anyones needs. It's very quiet and doesn't sacrifice much airflow in doing so. The rubber mounts are great and easier to install than other rubber fan mounts I've used. (Read More)
