Manufacturer description
The Noctua NF-A8 PWM is an 80mm case fan built for compact builds where every decibel counts. The 4-pin PWM connector lets your motherboard scale the fan anywhere across a 450-2200 RPM range, and the bundled Low-Noise Adaptor caps it at 1750 RPM when you want it near-silent under load. At 80x80x25 mm, this Noctua fan drops into HTPC, Mini-ITX, and small-form-factor chassis as either intake or exhaust, and it is a common replacement for the loud stock fans in NAS enclosures and similar equipment. The box includes anti-vibration mounts, fan screws, an extension cable, and a y-cable for running…
SpecPicks Verdict
SpecPicks scored Noctua NF-A8 PWM using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. Noctua's PC & gaming hardware lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for PC & gaming hardware of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How loud is the Noctua NF-A8 PWM?
Noctua rates it at a maximum 17.7 dB(A) at its top speed of 2200 RPM. The included Low-Noise Adaptor limits it to 1750 RPM for quieter operation.
Will this fan fit my Mini-ITX or HTPC case?
It uses the standard 80x80x25 mm format, so it fits any chassis with an 80mm mount and 25mm of clearance. It works as either an intake or exhaust fan.
Can I control the fan speed automatically?
Yes. The 4-pin PWM connector lets a motherboard PWM header scale the fan across its full 450-2200 RPM range based on your temperature curve.
Can I use this to replace a noisy NAS fan?
Noctua lists NAS units and similar 80mm devices as intended replacement applications, provided the device uses a standard 80mm mount and a 4-pin header.
What comes in the box?
The fan ships with anti-vibration mounts, fan screws, a Low-Noise Adaptor, an extension cable, and a y-cable for running two PWM fans on one header.
