> 3 dayI ordered this along with a NF-F14 PWM to replace the stock non-PWM fans on my NH-D14 CPU cooler. After installing these fans, I noticed a clicking noise common with PWM fans. After reading reviews and descriptions from Noctuas website, I was led to believe that Noctua had eliminated the dreaded clicking associated with PWM fans. I was ready to send these back and go back to the stock fans when I decided to make sure these were the culprits. After process of elimination, I determined it actually wasnt these fans, but one of the stock fans on my case! I hadnt noticed it before due to the stock NH-D14 fans being a little louder, but these are so quiet it allowed me to hear the subtle clicking from the stock Corsair AF140L on my case!

Greater than one weekI could not get it to run despite contacting Noctua several times. It ended up in the trash bin.

> 3 dayI wanted to mount them on my Antec 920 because it had 120 mounting holes. But then I decided to put them as exhaust on the top of my case. (this goes out to you corsair 500R owners or any case that has just the right amount of room on the top grill) They didnt match up to the holes unless i was about to use one, then I noticed that i could fit both without using any fasteners to keep it in place because the grill held both fans down sturdily.

> 3 dayWhen I started to built my new computer, I wanted to pick every single parts that are high quality and will last me a long time before I have to built another one. One of the key to keep the computer running well is cooling, today there are many case out there that use multiple fans and some are big and some are small, this fan is just the right size for my case, I picked this because I also did research on the heatsink and I used heatsink from Noctua as well and they are excellent and quality item. so far this fan is really really quite and it moves heat very well, you wont be disappointed.

> 3 dayThis baby pulls a lot of air and is very quiet. I like how it fits on the standard 120MM mounting holes. Very high quality too.

> 3 dayThis cooling fan cranks i have two on my cpu one inflow and one outflow on the opposite side. Thought I would need to water cool but the noctua has kept my 16 core cool even when rendering for 16 hours straight with all cores at 100 percent.

The NF-A15 is a premium quality quiet 140mm fan with a round frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. The NF-A15’s frame features 120mm mounting holes (105mm spacing) and has been enlarged to 150mm width in order to provide superior performance on today’s high-end CPU coolers. Featuring 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 ensure 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.
Round 140mm frame with 150mm width
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 heatsinks, its 140mm height doesn"t make it extend on top and thus ensures best case compatibility. The NF-A15"s standard 120mm mounting holes (105mm spacing) also make it an ideal performance upgrade for 120mm case or CPU fans.

Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
SSO2 bearingThe 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. |
Flow Acceleration ChannelsThe 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. |

AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) 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.
