Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown)

> 3 dayI got this to replace the loud slightly whiney foxconn cpu cooler in my HP Pavillion Ryzen 3600 gaming computer and it did lower the volume, and it even slightly lowered my CPU idle temps, but my cpu temps under heavy load from video rendering went from 64.5 to 74c. ( i found disabling the turbo boost brought the cpu temps under heavy load down to 55c). Too bad my case wont let me install an 80mm to 92mm fan adapter so I could install a quiet but powerful Noctua 92mm PWM case fan as my cpu fan. :( But for case fans you cant beat this fan if you value a silent computer.

> 3 daysuper happy of these fans it exhaust all of the hot air from my Corsair 250D and does it without making any noise!!

> 3 dayMy recently bought enermax 80mm fan was rattling and making buzzing noises even at low rpms. So I bought this one because Ive been reading about how great noctua is...

> 3 dayReplaced the fan in an Icom IC-7300 HF radio. Was easy to do (thank you, YouTube) and works quite the treat. I keep an eye on my radios temp while sending. But so far, even though it moves less CFM, been well pleased.

31-10-2024its so quiet its shocking not to hear any fan case noise when the PC is on, I thought it wasnt running but looked at the fans with a flashlight, and they spin, but are silent, good quality, really improves PC time with a quiet background

> 3 dayWorked great, so much quieter than the foxconn heatsink fan i had before.
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.
