Designed for DIY professionals gaming enthusiasts, the highly acclaimed Noctua NF-S12A FLX case fan incorporates a host of design innovation and technology to deliver first rate cooling and acoustic capability you expect for your gaming rig. 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 FLX version provides 1200/900/700rpm speed settings via the supplied Low-Noise Adaptors in order to give you full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling.

  • newegg Award-winning S12 design The NF-S12A features the third evolution of Noctua’s classic Straight Blade Design that has earned its S12 series countless recommendations from hardware journalists and enthusiasts around the world. Further optimised for even better airflow/noise efficiency, it makes the NF-S12A an ideal quiet case fan.
  • newegg Cools quietly Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua’s unique Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency. And the latest version of Noctua’s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises.

  • newegg Low-Noise Adaptor The NF-A15 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 1200 to 900rpm. The L.N.A can be used either to run the fan at a fixed speed of 900rpm or to cap the maximum speed when using automatic PWM control.

5 out of 5 eggsThese fans are beyond excellent

Pros: I bought two of these fans. Installed it to side panel in original PHANTOM case. These fans are quietest fans, I couldn't hear any noise or sound. I had to open the side panel to make sure that they are running.

Cons: None

Other Thoughts: These fans are expensive than other fans, but they are totally worth every penny.

5 out of 5 eggsBest Fans hands down

Pros: Best fans I have ever owned.
No issues at all and I have had these for over a year and a half.

Cons: Some people do not like the color. I like that they stand out a bit .. when someone looks at your case they can tell you use the best. But for people that only are after aesthetics then maybe not.

Other Thoughts: Seriously .. these are creme of the crop. alot of people not keen on the color.
These things reek engineering and quality.
But Ill take performance over glittery blinking fans any day. I have used corsair, antec, nzxt, xspc fans and they don't come close to these when it comes to amount of air moved and how quite these are.

5 out of 5 eggsExcellent Case Fans

Pros: These fans are very quiet and move a lot of air.

Cons: None

Other Thoughts: I bought 4 of these to replace some fans in my two computers. They move at least as much air as the old, noisy fans for much less noise.
These fans come with some rubber mounting dealies that I couldn't use with my case, but even with metal screws these fans are nearly silent.

5 out of 5 eggs

Pros: Very high airflow, but the exhaust does not feel like a leaf-blower
Keeps everything cool
Great build quality
Comes with great cable options
I can barely hear them/can't hear them under normal use. They are also stunningly quiet at full speed

Cons: Low noise "screws" can be annoying

Other Thoughts: I am using these fans as an exhaust and they are amazing! I highly recommend them. You get used to and come to appreciate the color.

5 out of 5 eggsSilent is almost an understatement

Pros: * Extremely silent even at the highest setting. No idea why someone would use the low noise adapters.
* Anti-vibration pads are built in the corner so doesn't require any installation.
* Cables are really nicely sleeved which helps organizing your cables and avoid interrupting airflow.

Cons: Although I like the idea of anti vibration mounts, they are extremely hard to install depending on how your case is built and which fan emplacement you are installing it in. You'll most likely need tweezers to pull on the mounts in order to slip in the locking system over the screw holes.

I managed to setup one of my fans with the rubber mounts, but the second one I gave up and simply used a plastic rack that comes with my case. If you want to us the rubber mounts for most of your fans, you'll most likely need to remove all your components in order to have as little impedance to your reach/movements as possible. Maybe I'm doing it wrong so still giving this 5 star as the fans are supreme regardless.

Other Thoughts: Seriously, if you want silent fans these are the ones for you. Sure they are more expensive than the alternatives, but it's only a few dollars and totally worth it.

5 out of 5 eggsSimply The Best

Pros: Quiet. Fluid design. Incredible warranty. Excellent addition of extra cables, extensions, and silence solutions.

Cons: Absolutely ugly.

Other Thoughts: I used two of these to replace the fans on my ASETEK AMD Performance radiator. They are MUCH quieter than the stock fans and move A LOT more air, efficiently. They mounted just as a standard 120MM fan would and the extensions provided me the option to tuck and run these cables off cleanly.

5 out of 5 eggsMy first nice fan. Worth it.

Pros: Quiet. Moves a lot of air. Comes with rubber mount things so you don't have to mess with screws. Comes with different resistors so you can slow the fan down if you want, but even at the highest speed you can't hear it so I don't see why you would want to slow it down.

Cons: A bit expensive, of course, but this brand is known to be one of the best.

Other Thoughts: One of the reasons I went for this fan is that my mobo only has a 3-pin connector. If I upgrade my mobo, I'll have to get an adapter. For the price it would be nice to have variable speed, but that would require 4 pins anyway.

5 out of 5 eggsGet what you pay for

Pros: Quiet
Good air flow
Amazing build quality
No screw installation
Included accesories

Cons: None

Other Thoughts: So I recently put together a build for my friend who requested something quiet. I went with 4 of these with a few other Noctua fans, and man I am impressed.

There's not really much to say, Noctua pretty much makes the best fans you can buy. They move a seemingly impossible amount of air for how much noise they make. Included in the box is a daisy chain compatible Molex to 3-pin fan adapter, which was a nice touch, along with 2 low noise adapters, screws and rubber attachments.

Great fans. If you're looking for the best and don't mind spending a little extra you really can't go wrong with this fan, or really any Noctua fan.
