  • Noctua's NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 140mm fan. the NF-A15/14 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
  • The NF-A15 is tailor-made for use on today's high-end CPU coolers: While its 150mm width matches those of most high-end heat sinks. The NF-A15's standard 120mm mounting holes also make it an ideal performance upgrade for 120mm case or CPU fans.
  • The NF-A15 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
  • Noctua's AAO (Advanced Acoustic Optimization) 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.
  • Noctua's Stepped Inlet Design adds turbulence to the influx to facilitate the transition for laminar flow to turbulent flow, that reduces tonal intake noise, improves flow attachment, incur suction capacity, especially in space restricted environments.
  • Integrated Anti-Vibration Pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
  • Supporting fully automatic PWM speed control, the NF-A15 PWM uses Noctua's novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology which makes the fan quieter at low speeds.
  • The NF-A15 features the further optimized 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 stabilization, precision and durability.

The lower the RPM, typically, the quieter the fan.

If you don't want to read everything I have to say about this fan, let me sum it up: This fan is awesome. Very quiet and powerful. It comes with useful adapters and mounting solutions. I recommend it completely.

I picked this fan up to replace the top mounted 200mm fan in my Corsair Obsidian Series Black 650D Mid Tower Computer Case (CC650DW-1) as it's a bit louder than expected and the front 200mm fan is broken (Corsair doesn't seem to care enough to return my emails about my RMA, but that's another story), so I moved the top 200mm fan to the front and removed the broken fan, leaving this one up top. Now, the 650D is designed to take dual 140mm fans as far as I know, but due to the wider design (140mm x 150mm) that isn't possible and I'm limited to just one. To be honest, I don't think I need a second fan. This one moves so much air with so little noise (currently using the low voltage adapter - more on that in a second). I'll probably get a 120mm Noctua fan to replace the stock rear fan Corsair ships since these are so great.

This fan is designed for high resistance applications such as CPU fan coolers, however, it works just fine so far as a case fan. It comes with a great set of accessories including extension, split and low voltage (speed/noise reducing). Regular screws are included, as are silicone "screws" which are better at reducing case vibrations.

Did I mention a 6 year warranty? On any computer part with moving components that's amazing. Fan failures are pretty common (they break down and make a ton of noise usually) so having a long warranty on this is great.

I have a Noctua NH-C12P SE14 CPU cooler in my latest build. It came with the 140mm round fan, but it had the 3pin power connector instead of the newer 4 pin PWM connector my motherboard wanted. The CPU heatsink is a huge thing and this 140x150x25mm frame fan is a better fit than the round version. The heatsink is a down facing model with the fan blowing down on the motherboard components. Big bonus is it seems a little quieter than the previous fan. Not sure if it's the level of the noise or the color of the noise, but it sounds better. It comes with removeable rubber pads to keep vibration to a minimum in applicable installations. They didn't come into contact in my situation, so I removed them; but they would be sweet in other applications. SpeedFan 4.47, a Windows monitor utility, picks up the RPM signal from the fan. I don't bother adjusting the fan speed, it's quiet enough to just run full speed all the time, which also gives max cooling to the motherboard components. Color ? It's a delightfully ugly color that grows on you. Yeah, it's subversive and expensive, but capitalism at it's finest.

This fan is quite and has a lot of power of moving air. It 4 pin (pwm) fan makes it excellent for it to be attached to the mobo if you don't have a fan controller.

What can I say except that it is quiet and I'm willing to pay for silence. I built a new desktop computer and researched the quietest cases, CPU coolers etc and then changed some of the fans to these. I can't hear it. I love the silence. The motherboard PWM controller works with these fans perfectly.

i have it in a pull configuration on my Prolimatech PRO-MGH-C Megahalems Revision C CPU Cooler. never thought it would work without a push configuration but my case was limited in room (SilverStone Temjin TJ08-E) so i tried it. at the very top end of RPMs (1200plus), there's a noise i don't like. i dial it just under this, high 1100s. at this level this thing is exquisite in function and silence.

By Henrik Buus Jensen on April 18, 2014
I just had this installed as a case fan.

When I'm just surfing the Web, the fan is at 700 rpm default but even at that low amount of rpm, the fan makes a certain little noise, that, although quiet in nature, can get very annoying to listen to if your other pc parts and your surroundings are very quiet.

Using the supplied Low Noise Adapter-cabel cuts the fan's rpm down to 550, and this makes the noise in question acceptable to listen to.

I'm using a Fractal Design Define R4 noise protected case and a XFX 850W Black Edition PSU.
The latter comes with a so-called hybrid mode, meaning, using a switch on the PSU you can choose to enter a mode where the PSU fan is turned off completely at low loads.
Therefore the only things in my case that make noise are the CPU fan (Noctua NH-U14S) and the case fan (Noctua NF-A15 PWM).

Using Asus Fan Xpert2 I can turn off the case fan completely and thus only listen to the CPU fan.
The CPU fan only runs at 225 rpm when I'm surfing the Web and is in fact completely silent.
You simply cannot hear it.
Turning on the case fan again brings back the annoying noise I referred to above.
Therefore I know 100% certain that it is indeed the case fan that makes the annoying noise I am speaking of.

I know that the NF-A15 PWM fan is supposed to move more air than the competition, but still, I think it is a little disappointing that such an expensive fan makes such an annoying little noise, even when the CPU is running low intensity jobs such as web browsing.
I should mention I have tried other case fans in the past (by Noiseblocker) and it's quite possible to get a fan that is 100% silent at low CPU loads.
