> 3 dayI have been using Noctua for years, it is a high end fan I use for most PC builds, this is not a value added item because Noctua is a high cost brand, to half justify the cost they do perform as intended by manufacturer.

> 3 dayThis fan lives up to its reputation. A lot of extra goodies come with it, easy to install, very quite, and moves air through my TX3 wonderfully. The two-tone shades of brown are not easy on the eyes, but that doesnt take away from the fans performance. A shout out to Noctua for making great fans.

> 3 dayMy Dell PC was getting hot playing some quasi graphic intensive games. The factory fans were just not cutting it, so after reading some reviews, I picked up one of these fans and installed it. The installation, overall, was very easy. I like the fact that they give you a splitter so that you can either add it as an additional fan or use your old fan as a secondary, which is what I did. It was harder to remove the factory fan than it was to install this one.

Greater than one weekUsed this to add an intake fan on my Dell tower. Works like a charm and all the extra cables were very handy.

Greater than one weekGood packaging and presentation. Fans install easily with vibration-compensators (rubber plugs). Great build quality and plenty of accessories. I replaced the exhaust fan and added a second fan for push-pull configuration. Highly recommended. BTW I know that the case looks close to the back wall but its actually 6 inches away.

Greater than one weekI purchased this to match the same NF-A9 fan included with the Noctua NH-U9S CPU cooler.

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.
