Description

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. 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. Read more Flow Acceleration Channels 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. SSO2 bearing 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 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.

  • Super quite fan
I replaced the fan in a Behringer NX1000D with this unit. Fit is excellent and it runs silently now. I run the amp 8 hrs a day and have not had any overheating issues. It’s a little more expensive than other options but I’m satisfied.

  • The fan quite and has a higher air flow than the fan that is replaces.
I bought a AC/DC powered solid state mini fridge/cooler. The cheap fan that it came with did not blow much air. So, I bought this Noctua fan as an upgrade. I am going to say that the airflow with this fan feels about twice as much as what came with the beverage cooler. You practically have to put your ear up to the case to hear it. I definitely noticed a difference in cooling performance. If I buy a second cooler from home, I would buy this fan again. ... show more

  • Super quiet
I use this as external fan to my computer to move the hot air from the back of the computer inside an enclosed cabinet out a hole in the back. It is so much quieter than the previous fan. I'm using it on the middle speed (the high speed is still pretty quiet, but I don't think I need that much airflow). I didn't understand how the "extenders" worked, but then I noticed that they have labels that said something about different speeds, so they must be some sort of resistor to slow down the fan. If it really is a resistor, it'd be nicer if there was a different way to changing the voltage/current than just wasting the power going through a resistor, but I don't know how they actually work, so maybe they do have a better power-efficient system. ... show more

  • Universal fan and switch
There is no doubt in my mind that the rubber on each edge is made perfectly. Canceling noise and vibration this fan will do its job.

  • Great for a Kenwood TS-2000 Ham Radio Upgrade
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

  • Outstanding quality and unbelievably quiet
I used this fan to replace the stock cooler in my Behringer iNuke 3000 amplifier. The stock cooler was extremely noisy, even at base load. I have the amp setup in a home theater app so the loudness of the stock fan couldn't be tolerated. I swapped the stock cooler for this Noctua. All I can say is WOW. The fan is completely inaudible at base line AND under load. Granted, I don't think it moves quite the CFM as the stock cooler, but I've had no thermal overload issues so far. I'd definitely recommend this for someone looking for a high quality cooler that is SILENT. UPDATE: 09/28/19 I ran the amp at full tilt (almost to clipping) today and managed to trip the thermal overload fail safe. This was more of a benchmark test than a real world continued use. That said, the fan couldn't move enough air to keep cool under a max load, but it does just fine for normal use. Still 5 stars got quality and lack of noise. ... show more

  • Best fan period!
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
