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 pads
Integrated 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.
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.
Flow Acceleration Channels
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.
Scope of delivery
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.

So if you are someone that bought the NH-D15S and still want two fans like the NH-D15, you are forced to pay extra for the chromax NF-A15 instead of the standard one, even if you don't care about the colors.
Expensive vs Chinese brands like UpHere but for cooling a Threadripper CPU I think the price is worth it.
Sure the cpu is now 2 degrees higher under full load, but now I have pwm so it doesn't annoy me and it's on a 4670K reduced to 4ghz since it's in my gf's pc now and....Well she doesn't game lol
I love noctua fans because with the MSI motherboards (intel h series etc) the fan can spin as low as 187 RPM. and it will not stall if you stop it with your finger. (Other fans can spin at around 500 but they will not start at that speed)

Reviewed in Mexico on August 25, 2020
I bought these fans to be quiet, so the anti-vibration pins and the low-noise adapter was a big factor for me getting these fans, and for them to be missing is a heart breaker.
I will update this review if Noctua responds to my email and sorts this situation out as they should. If not, my two star review is staying, which is a shame because these fans do seem pretty solid from what I have seen out of them. But when you do not get what you pay for, it is hard to not have a negative experience.
