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 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 2200 to 1750rpm. 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.

Quieter and cools way better than stock fans
Size: 80x80x25mm
These Noctua NF-A8 PWM fans were a great upgrade for my server, replacing some louder, less effective small fans that came with the build. Noise level dropped significantly, these run much quieter even at higher speeds. Cooling performance improved noticeably too, better airflow and lower temps than the fans they replaced. Classic Noctua quality, definitely worth the price if you want quiet, effective cooling for a small form factor build. ... show more

Super quiet, super cool
Size: 80x80x25mm
Amazingly effective, super quiet. Replaced the stock Intel cooler with this on a 10900k and it went from 40C at idle to 26C. It's also MUCH quieter despite this larger fan and two additional case fans from Noctua.

Noctua makes the best fans
Size: 80x80x25mm
I purchased a Rack Choice 2U 12-bay server chassis for a recent UNRAID build. The 4 fans that came with the case were extremely loud when I actually got them running. I ordered 4 of these Noctua NF-A8 fans to replace them. Once I installed them, all 4 worked very well and were so quiet I couldn't tell that they were even on. I highly recommend these not only for server builds but for everyday systems as well. ... show more

High quality, great accessories and documentation. 6-year warranty.
Size: 80x80x25mm
After buying a cheaper fan and having it fail within a year, AI recommended this one. It was right. Excellent product, great accessories, high quality, fast delivery (I realize that is more Amazon than the manufacturer). Impressed with the design, quietness, quality, and the documentation included. 6-year warranty blows the cheaper options away. Temperature sensors indicate it is meeping my Ryzen 2700X cool, attached to the Deep Cool heat sink that came with the PC. ... show more

cool and quiet
Size: 80x80x25mm
I replaced a dell optiplex MT i3 cpu fan, which rated much higher than the noctua. I thoughy I'd sacrifice flow for quietness. However, it immediately dropped a coulple degress at idle, and prime95 stress tests stablized around 78C after running for hours. At full speed, it's much louder than at idle, but the noise is low pichted and much tolerable than whining nosie. Although the Noctua fan is quiet, cpu fan is not the only souce of noise. I found my computer case itself makes some annoying metalic noise due to harmonic viberation with gpu and cpu fans. I could reduce the viberation noise by holding the case tight. I will probably apply some electric tape or clamps to tighten the case. ... show more

Huge upgrade for my QNAP — dramatically quieter and cooler
Size: 80x80x25mm
I installed these 80mm Noctua fans in my QNAP TVS-h1288X, and I still can’t believe the difference they made. The factory fans were so loud that I could hear my NAS screaming from two rooms away. After replacing them with these, the fan noise has been cut by well over half. At this point, I actually hear my air conditioner more than I hear the NAS, and my AC is one of the quietest units I’ve ever owned. What surprised me even more is the cooling performance. I have four SATA SSDs installed that were previously running hot enough to regularly push into the 60°C+ range. With these fans installed, all four SSDs are now staying at or below roughly 50°C, even while the NAS is doing work. So I didn’t have to choose between quieter operation and better cooling, I got both. If you own a QNAP TVS-h1288X and are tired of the stock fan noise, this has been one of the best upgrades I’ve made to the system. The NAS is finally quiet enough to comfortably keep in my office. ... show more

High quality and fan, just like Noctua knows to make. Highly recommended.
Size: 80x80x25mm
At first I thought that the price is steep, but once I got it I understood why - Noctua surely knows how to deliver, and their products are of high quality. The box comes with variety of connectors, anti-vibrant mounting pieces, screws, and the fan itself has rubber corners so even when it is just seated on the desk it keeps it nice and steady with no vibrates on the table. Think out of the box guys - I ordered 2 of these along with power connector to USB cables so I could put one next to my optical router which gets quite hot, and another next to my Surface Pro 8 which also gets hot. Seems to do the job. The only thing I did not find all around the fan, is an arrow which tells in which direction the air-flow goes. So just know that it pulls air from the opened side and throws air through the side with the grill where the cables are showing. ... show more

They're so quiet!
Size: 80x80x25mm
Holy crap these things are quiet. I built a PC into a rack, and stole a fan off an old PC I had lying around, but it was only a 3-pin fan, and I wanted more control. So I was looking at a different brand, and the reviews mentioned that they weren't as quiet as Noctua fans. So I dropped the extra money to grab a pair of these. I set my curves, and while I know they're working - because my temps are about half of what they were before I installed them - I can't hear them, like, at all. My CPU temps went from around 55-60 degrees down to around 34-40, so it's definitely great at cooling. Yes, there are cheaper options out there, but if you want a dead silent, very efficient fan, this is definitely worth the money. ... show more
