> 3 dayReplaced the noisy humming fan in an inexpensive HTPC case with this fan. Used the adapter to reduce fan speed to 1100.. The anti vibration mounts eliminate any issues with noise being transferred to the case. This may be the best 15.99 I ever spent. That may seem like a lot, but eliminating the noise that came from the other fan made my ears happy. No change in before and after temps as measured by RealTemp. Noctura will be my go to in the future when I need any type of computer fan.

> 3 dayI bought Two of these for my new build. I purchased these ULN fans when i should have bought PWM. My mistake! I had them installed and both were working fine, however, within two weeks, one began to show signs of failure. Two days later, it failed. I returned it and ordered two of the PWM fans instead.

> 3 dayLove this fan. Cant believe how quiet it is, but fan screws absolutely rip this thing up when you are screwing them in. Make sure you have compressed air around for when you are finished. Its actually super annoying so I had to subtract 2 stars. Im not a fan of the screwless mounts, so for me this was a big deal. If you like those things, then you will love this fan. Its operating much quieter and much more efficient than the 120mm Corsair stock (plastic, cheap, clear) fan on the back of my case.

> 3 dayWorks, moves air, quiet. Will update as time passes. Installed on 2/14/2022 will see the life of it.

> 3 dayAn excellent fan, many cases have an extra 80mm mounting point or two, and this fan is perfect for squeezing some airflow onto a board that only has 2-3 fan headers, using the 3-pin end of a splitter (which I believe is included?), or with a 3-pin to MOLEX adapter (Which I dont think is included).

> 3 dayI replaced my 15 year old case fan with this fan. The old fan from the beginning was irritating to try to use the phone when the computer was running. I usually shut the computer off when using the phone. This fan is very quiet. I have two computers and I know my new one will have Noctua fans when I start hearing the case fans.

> 3 dayUsing this in a MSI Z170A M7 / i5-6600K build. You have to set the Smart Fan controls in bios first (didnt see my boot ssd otherwise) and then it is whisper quiet. I also have the NH-L12 low profile CPU cooler. when hooked up and the NF-P12 case fan. If you let the motherboard control these fans, you have a hard time knowing they are on. CPU and case temps are in the blue, even during video conversion. Love these fans and you cant go wrong with Noctua!

17-11-2024As always, superb quality in a great quiet fan, what we have come to expect from Noctua. Everything you need for mounting is included in the box in order to isolate the fan in its position.
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 ULN version provides super-slow 1400/1100rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand 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.

|
|---|---|---|---|
Flow Acceleration ChannelsThe 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 bearingThe 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 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.
