    I have two of these now one for the rear of my tower and other one I bought was 120mm for my cpu, for the money you pay for it’s definitely worth it , comes with everything you need to install it and the best part is it comes with a 6yr warranty which is awesome

    It came with every other stuff. Now I am waiting for other parts which Noctua Center send it to me so I can add the 2nd fan to my NH-U9S .

    This 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.

    I used this fan in place of the stock 96mm nzxt fan that came included in the kraken G12 bracket. Works wonderfully. I cranked it to 2000 rpm to cool my vrm and vram. Along with heatsinks, my temps on a 2080s do not exceed 67° at the hottest point

    The noise level advertised is using one of the resistor cables that come with the kit to limit the speed to 1500 RPM. If you install them without the resistor cable they run above 2000 and are very loud.They are what I would say is normal at 1500…They are not 17 dB… I can assure you that. My Iwatch said 62…I’m sure it’s not accurate, but I’m sure it’s not 17. They move a lot of air though.

    Pops right in. I didnt use the anti-vibration screws that it came with because I dont read instructions and I had no idea what they were. I used the included screws and there is absolutely no vibration. Almost silent and moves lots of air. I use mine as an external case fan and replaced my OEM fan. I would give it 5 stars but for some reason it has a slight delay in startup, which causes my motherboard to throw an error code on startup and I had to disable the alert in BIOS. I monitor my system temps but, for a less experienced user (who, lets be real, probably wouldnt be buying themselves a new fan, let alone a Noctua) disabling a fan failure alert in BIOS would be an issue.

    Another quality fan from Noctua that is whisper quiet... two thumbs up!

    Im currently in the process of building an ultra small expandable PC, and I had purchased a Noctua NH-l9i cpu cooler. I had been able to achieve a stable clock rate of 4.6 GHz, unfortunately in testing the cpu would hit the thermal throttling point. I wanted to see if I could push the overclocking boundary a bit, so I replaced the thin fan with this one. Theoretically, this should have worked. This fan has a higher CFM rating as well as a higher static pressure rating. In actual use, this was not the case. In the end, Ive returned to the thin fan. Now Just because this fan didnt meet my particular needs, Im not knocking it too much. If what you need is a smallish fan to quietly move lots of air, this will do the trick nicely.

    I use this as an exhaust fan in a home theater equipment cabinet. Very quiet and moves a lot of air.

    Noctua are the best fans Ive ever used.

NF-A9 PWM HeaderNF-A9 PWM Header

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 Channels

The 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 bearing

The 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 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.

Scope of delivery

  • NA-RC7 Low-Noise Adaptor (L.N.A)
  • NA-YC1 4-pin PWM y-cable
  • NA-EC1 30cm extension cable
  • 4x NA-AV1 anti-vibration mounts
  • Fan screws

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.
