Compact 80mm PWM fan for small builds

The Noctua NF-A8 PWM is a premium 80mm by 25mm case fan with a 4-pin PWM connector. It uses an SSO2 bearing and runs at up to 2200 RPM while producing 17.7 dB(A). The package includes a low-noise adaptor, Y-cable, extension cable, vibration compensators and screws for CPU coolers, radiators or chassis mounting.

Ideal for compact cases and noise-sensitive users

This 80mm format suits HTPC, ITX and small form factor builds where larger fans cannot fit. It also serves as a quiet replacement for NAS units or similar devices. Buyers who need higher airflow for larger enclosures or radiators requiring bigger fan frames should look elsewhere.

80mm frame with 25mm thickness decides fit

The physical dimensions of 80.00 by 80.00 by 25.00 mm determine whether this fan matches your mounting points. Verify the available clearance in your case, cooler or radiator before purchase.

FeaturesSucceeding the award-winning NF-R8
Noctua's NF-R8 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 80mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A8 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
NF-A8 Flow Acceleration Channels
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

Questions about this item

What motherboard header do I need to run the 4-pin PWM control on the NF-A8?

Connect the 4-pin plug to a standard 4-pin PWM fan header on the motherboard for automatic speed control between 450 and 2200 RPM.

Will the included Low-Noise Adaptor still let the fan spin if I keep my older 3-pin header?

The L.N.A. plugs into a 4-pin PWM header and caps the maximum at 1750 RPM; a 3-pin header will not provide PWM control for this fan.

How can I confirm the NF-A8 is running within its rated range after installation?

In BIOS or monitoring software the reported speed should sit between 450 and 2200 RPM (1750 RPM with the L.N.A. fitted) and noise should stay near 17.7 dB(A) at full speed.
