The NF-A15 PWM complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. It provides superior performance with the 120mm mounting holes (105mm spacing) which has been enlarged to 150mm width. Thanks to the sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 further improves the renowned quiet cooling performance of the award-winning NF-P14. Noctua’s custom designed PWM IC for fully automatic speed control and reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling and a Low-Noise Adaptor, the NF-A15 is a premium choice for the highest demands.

  • newegg Succeeding the award-winning NF-P14 Noctua’s NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 140mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A15/14 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
  • 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 SSO2 Bearing The NF-A15 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.
  • 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.
  • newegg Extensive Cabling Options The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-A15 PWM fan to the same PWM fan header for automatic control.
  • newegg Ultra-Low Power Consumption Despite of its further improved performance, the NF-A15 PWM consumes only 0.96W of power, which amounts to a reduction of about 20% as compared to its predecessor. This doesn’t only make it eco-friendly but also helps to cut down the electricity bill!

5 out of 5 eggsgreat fan

Pros: very quiet,
nice extra large size
120mm mounts create big compatibility

Cons: doesn't replace a good heatsink
More than one doubles performance

Other Thoughts: this fan won't solve your problems all by itself, but its the first step to a cool, quiet case. I am buying more. 140mm fans just can't replicate its performance for the given dB.... Careful about spacing, these can bump into other components....

5 out of 5 eggsQuiet, I can't hear my fans

Pros: Very quiet, stable when running and air noise, "what air noise" I did not know about a premium fan until I bought four of these to incorporate with my Corsair Hydro Series H110.

Cons: Purchased only four, I like them so much I am going to get three more from Newegg to put in the front of my case,

Other Thoughts: This build was fun and was very enjoyable up until I finished it. Now I don't have anything else to put together in this build.

5 out of 5 eggsNoctua, a Class of Their Own

Pros: What can I say? If you look at someone's computer and you see brown fans, you know they mean business, and won't blow your ear drums out doing it. High air-flow, and quiet. What else can you ask for? Oh, the color! If Noctua starts offering other colors, I will start looking at other fans.

Cons: These are 140mm fans, but the bolt pattern is 120mm. So if you plan to use these on a case that has 140mm holes, buy something else.

Other Thoughts: A ton of people complain about the color. I shun them, because Noctua fans are always noticeable. I define good air-flow by the color brown, thanks to Noctua. I hope that they never change.

5 out of 5 eggsawesome fan

Pros: very efficient. very quiet. variable PWM

Cons: The fans are big

Other Thoughts: they have all sorts of mounting holes for just about every occasion, but still had to modify one of the fans to fit the case. It was unexpected, but only took 5 min with an exacto blade.

I bought 6, two on water cooler, two on front, one on rear and one on bottom. With all six fans running I can barely hear them at all. the motherboard fan controller works well with these pwm fans. most of the time they are loafing around 400 rpms (asus maximus vi formula)

Pros: -Noctua warranty of 6 years
- Quiet
- Decent amount of airflow
- Packing and amount of cables is awesome

Cons: Mounting can be hard

Other Thoughts: Don't do what I did and think these were just regular case fans. While these are great fans and can be used as case fans these are mainly to be used for CPU coolers that use a fan of your choice. These fans are weird and mount in 120mm spaces.

I regret not buying the NF-P14 FLX to put in my 140mm spaces. I had no idea that this could even be an issue. It was entirely my fault but please be aware when buying these fans. If you want 120mm get the NF-P12. If you want 140mm, get the NF-P14. If you want a CPU cooler that has 120mm mounts and you want a bigger fan, get this.

5 out of 5 eggsSuper Fan

Pros: smooth as silk, almost inaudible

Cons: non

Other Thoughts: bought this as a 2nd fan for push/pull with my NH-U14S. while this isn't a "con" you DO need to make sure you have room for these. I'm only populating 2 memory slots...I'm using some Corsair Vengeance RAM which has a tall heat sink. If I was going for 32 GB with all 4 slots the fan wouldn't clear the memory.

4 out of 5 eggsNice Fans, Tough Mounting.

Pros: Excellent build quality. High-end packaging. Top notch accessories. These fans just ooze class. Once I got my motherboard settings dialed in (MSI Z87-G45) the fans started working beautifully. If you're not absolutely crazy about system and CPU temps like me, this product is a no-brainier upgrade. Six year warranty really says something these days.

Cons: I bought two of these PWM fans to replace their non-PWM counterparts on a Noctua NH-D14 CPU Heatsink. Mounting these fans meant extracting my motherboard from my case and fiddling with the mounting clips for several minutes. It was a somewhat of a struggle getting these fans clips to heatsink itself and it is a process I don't plan on repeating until I absolutely have to. Docked one egg for that. However, don't let my experience keep you from purchasing an otherwise great product.

Other Thoughts: Gotta love Austrian engineering!

5 out of 5 eggsIf you have room around 120mm mounts--THIS

Pros: Oversized, quiet, good airflow, really really nice connector accessories.

I got 1 of these and 1 of the Noctua NF-P14 FLX 140mm fans to check them out and compare. I love them both but they are (obviously) very different. Let's discuss!

First off: my rig is in a Rosewill Challenger. I'm not a Newegg fanboy or anything I just know a good deal when I see one.

Let's assume you already understand both of these fans I'm referencing are basically 140mm fans that mount on 120mm holes. Period. This is both a pro and a con but for now, let's just have a moment of silence for how awesome it is to be able to force a bigger fan on a very constrictive mounting size. I suspect in the future the trend will continue and we will see oversized 140mm mount fans that are actually 160mm around or something. I will buy several of those also.

So I'm running a good old CoolerMaster Hyper 212 Evo and it *just* barely fits my case, and makes it so you can't use the top of two side panel fan mounts. This particular fan is the best possible component to install in the remaining bottom side panel mounting position. The mounts are just holes drilled in the panel, which is ideal here. Although it doesn't look very nice, I've used the included rubber screw mounts to provide something for the fan to vibrate against without causing the panel to rattle at all, and they are very effective, as were the ones provided with the Rosewill Hyperborea 120mm fan this Noctua replaced. In comparison the Noctua rubber screws are much sturdier but Noctua uses oversized fan mounting screws to accomplish this. As a result you can't use Rosewill's snazzy but brittle black rubber screws on the Noctua. Somehow I suspect 4 black screws to mount the NF-A15 to the panel would be just as effective and quiet, and I will probably test that out soon. The main reason I think this type of oversized fan is perfect for metal panels like this scenario is the integration of the corner rubber silencing dampeners. They rest against the side panel and keep any vibrations to a minimum. The design of this fan actually stiffens the side panel of my Challenger, which is a bit flimsier in concept than practice. It's harder to bend than it seems. Still. This fan is beefy and perfect for this application.

I must say, without a big clear panel to view these fans through and against the surprisingly dark matte finish of the Challenger panels and mesh, these fans almost look white--they really don't look bad seen through mesh at all. I read somewhere that Noctua is planning to release upcoming fans in black, and that would be ideal if it is true.

The included accessories sealed the deal for me on this particular model. They totally blow the NF-P14 FLX package out of the water, incidentally. I ended up actually NEEDING the PWM Y splitter, which is nicely sleeved, as are the extension and low-noise adapters. The Y splitter is brilliant for side panel installs, which are often hard to reach without overdoi

Cons: If you don't have 120mm mounting holes, this wont work.

If you don't have extra space around the mount to accommodate the rectangular shape, this won't work.

Colors are odd. Rubber screws are brown.

Occasionally unjustifiably priced almost everywhere. Be savvy.

Other Thoughts: To round out the review, I wanted to highlight the final comparison with the NF-P14 FLX . Where did I end up putting it? On the Hyper 212 Evo CPU cooler. That's really where it made the most sense. This simple upgrade was worth some noticeable change for the better in CPU temps, though I hate to be specific because there were other variables involved.

Just looking at the setup it is obvious that placing the P-type (pressure) 140mm fan which has normal 120mm mounts and a completely round shape on the CPU cooler instead of the bulky square-shaped 120mm fan supplied with the Hyper 212 Evo will be much more effective. Not only does it seem like the CPU is happier, but the fan actually seems both to promote better general air circulation in that region of the case (you can actually FEEL it pumping air all around it) AS well AS make the atrocious Cooler Master EVO heatsink a bit more interesting to look at. It kind of swallows one side of the block, so I think a second would almost hide the thing and make it look like a fan sandwich. I'm so going to do that.

Anyway, as I stated earlier, both this NF-A15 PWM and the NF-P14 FLX (which isn't PWM but quiet at full speed so who cares) are fantastic, but very different and for different applications.
