> 24 hourInstalled two of these into my desktop. Very simple to install, lots of extra cords for hookup (If needed). Ultra quiet, I cannot hear any noise from them at all, great value.

> 24 hourI had always heard noctua was a premium brand because of how good it is. But i never really understood til I actually bought one. The case i put this fan in has no glass panels so I don’t really care about the color scheme but this fan is 1000x better than the stock fans my PC came with; pushes more air out while being quieter, and all the extra stuff this fan comes with is really helpful instead of having to buy multiple things

> 24 hourCompatible with Noctuas NH-D9L D-Type Tower cooler. Seamless fit. In this case bigger IS better !!!

> 24 hourRuns quietly and produces a lot of air , about 50 cfms

> 24 hourI liked the promise of a quieter case fan in a HP 8200 Elite CMT with a slightly borked UEFI, but I couldn’t use it due to HP’s proprietary PWM case fan connector. The unused TFX connector wouldn’t let that fan work at all.

> 24 hourSolid quality, quiet and smooth. My second noctua on a dell tower that sounded like a hurricane. My first noctua on this tower has been there for two years. Buy it if you need a fan or cooler.

> 24 hourI like Noctuas fans, but I knocked off a star because they are so high-priced.
The NF-A9 is a highly optimised, premium quality quiet 92mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9 further improves the renowned quiet cooling performance of the award-winning NF-B9. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 2000 to 1550rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.
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.

|
|---|---|---|---|
Flow Acceleration ChannelsThe NF-A9 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. |
SSO2 bearingThe NF-A9 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. |
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. |
Scope of delivery
|
Inner Surface Microstructures
With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
