> 24 hourIt runs silent and cool. Does the job really well.

> 24 hourJust a great set of fans that really do the job. PWM fans can be controlled with the motherboard and have near silent operation at maximum power. The Fans are just built great and keep the system more than cool. I would highly recommend them. They come with splitters so you can add more than one of these to one fan header. Just be aware the splitter only measures the RPM of one fan and inputs voltage into both.

> 24 hournot as quiet as I thought they would be.

> 24 hourFor 80mm fans, they are still very quiet...

> 24 hourIt hasnt died or started squeaking, chirping or making any unusual noise. It runs relatively quiet for the expected amount of airflow. It does have onboard RPM sensors. Made a little bit of electrical interference noise running PWM, but works fine in DC. Chocolate Brown and Beige doesnt exactly match the black PCB and interior of my case, but may look right at home in your 80s performance build with a 5.5 Floppy. It does the job.

> 24 hourThese are the best fans in the world for a reason... and even though they are the most hideous PC parts that Ive ever seen, I dont think that Ill ever go back.
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.
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.
