> 24 hourI replaced a cpu fan in Thinkcentre M93p. It works, but fails POST, as lenovos motherboard does not support zero rpm mode that this fan has, giving the two beeps and cpu fan error. Or something else might be the issue, but that is why I took down one star. Other than that, it is a great fan, silent, and with good airflow.

> 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 hourIm pleased with how quiet this fan ended up being once I installed it. Like, case fans are mostly a commodity item, unless you want a fancy-looking case (which means a transparent fan with LEDs) or a quiet case (which means fans like this one).

> 24 hourUse it to cool my nvme ssd on the back side of the motherboard. Even at full speed it is still very quiet.

> 24 hourBought 5 of these for Home server, can’t even tell it’s on with how silent it is.

> 24 hourI bought a Dell 3880 and its a great little system... EXCEPT THE CPU FAN IS TOO NOISY. If youre in a quiet environment then you will almost certainly notice the noise.

> 24 hourThe fan I was delivered had no damage to the box, yet the fan was not as quiet as the factory cooling fan on my old dell xps8700.

> 24 hourAt first my PC sounded like it was ready for takeoff and now I can barely hear it. It keeps my PC cooled and its not noisy. 10/10 would recommend
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.
