Description

Noctua's premium cooling components are internationally renowned for their superb quietness, exceptional performance and quality. The NF-A8 is a highly optimised, premium quality quiet 80mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8. The FLX version provides 2000/1650/1200rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands. 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. The NF-A8 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. The NF-A8 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 made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. 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.

READ if this is for a 3d printer.
Size: 80x80x25mm
These fans are incredibly quite and as a maker I've found many uses for them. My opinion is they do not move enough air to cool the hot end of a 3d printer. I did use a larger 80mm version for the mother board and power supply. It's not the fans fault, quiet equals low air flow. And there 12 volts not 24 volts so you'll need to add a buck converter. ... show more

Whisper Quiet using Ultra Low Noise Resistor Included 😁🖥️⌨️🖱️👍
Size: 80x80x25mm
Used inside power supply that got fried during a lightning strike that I had to replace and the new on had a loud fan. I wanted my computer to sound quiet the way it was before, since the power supply was proprietary I could only change the fan, this was perfect, with a little trial & error I first hooked it up and it was loud, then I rewired it with the included Ultra Low Resistor and it was whisper quiet. ... show more

Great for a Kenwood TS-2000 Ham Radio Upgrade
Size: 80x80x25mm
I bought 2 of these fans to upgrade the stock fan in 2 Kenwood TS-2000 ham radios. It is thicker than the stock fan but there is plenty of clearance. The stock screws can be used in the rear of the mounting holes as they are not long enough to go through the whole fan. I may hunt down some long 2 mm screws someday to complete the installation but it works great as it is. The fan is much quieter than the stock fan and moves a lot more air - a lot more. You have to put your ear right up to the radio to hear the fan. This is great for cross band repeating, Kenwood Sky Command, or digital modes like PSK31 or JT65 that create a lot of heat. If you like it quiet you can even do this if you aren't running any of these modes. Keeping the heat down keeps the finals alive! . This is a high quality fan and it comes with lots of adapters if you are going to use it in a PC. The fan in the TS-2000 is ground switched so if you put a 1 watt, 100 ohm resistor between the fan ground and chassis ground the fan will run at low speed all the time and switch to high speed when the relay closes. It is an ideal fix. ... show more

Awesome fan!
Size: 80x80x25mm
Super fan, lots of air flowing and very nice quiet hum. The Noctua fans come with an amazing array of power attachments to connect it, and control the fan speed. Also comes with silicone mounts and screws so you have your choice of mounting. Corner pads also make the mounting solid and quiet as they absorb vibration. Top of the line fan! I don't even look at specifications of fans anymore. I just look for the Noctua fan which is the size I want and then get it. Other fans may look better on paper, but you can't beat the Noctua engineering for a good balance of design, construction, longevity (6 year warranty), and durability. And let's face it - they're not THAT much more expensive. You'll easily forget the price difference in the long run. ... show more

Best fan period!
Size: 80x80x25mm
It's a Noctua, so you know it will be a quiet, solid performer. And this one lives up to their reputation. Worked perfectly as a replacement for a stock cooling fan in an audio amplifier. Everything about this fan says 'quality', and I am continually impressed by just how superior the Noctua's performance is, over what can look like nearly-identical fans. They move more air, with much less noise, than any other fan on the market. And I have found this to be the case with ANY fan that Noctua makes - they are a superior company making a superior product. Worth the premium! ... show more

I've found my new Gold Standard in silent case cooling fans.
Size: 80x80x25mm
I purchased the Noctua NF-A8 FLX 80mm fans to replace the stock fans in my Synology NAS box in order to achieve higher air-flow and quieter cooling for the always-on NAS box. I am a veteran computer builder and technophile, however this was my first experience with the Noctua fans. I was extremely impressed right out of the box. The fans connect to your device with rubber pins instead of the traditional metal screws (which can be a source of vibration noise) and the fan spin is inaudible unless I stick my head right down next to it - part of the reason for the whisper-quiet functionality is the exceptional air flow created with the unique fan blade design. The Noctura fan is running at about 75% of the speed of my old fans while still producing a slightly cooler in-box temperature. In short - they are a bit more expensive than standard 80mm fans, but I will absolutely be going with Noctua in all my future builds. ... show more

Excellent Fans for the Synology DS1513+
Size: 80x80x25mm
I purchased two of these fans to replace the two fans in my Synology DS1513+ NAS box. The old fans were over ten years old and the bearings were wearing out and creating noise. These new fans fit perfectly and eliminated my noise problem. I am very satisfied with this purchase.
