Title: Noctua NF-A8 PWM — 80mm Premium Quiet Fan (4-Pin)
 
Short Excerpt: Quiet, pressure-capable 80×25 mm PWM fan for tight spaces, heatsinks, and cases. 2200 RPM max, 17.7 dB(A), ~32.7 CFM airflow, SSO2 bearing, AAO frame, rich accessory bundle, 6-year warranty.
 
Overview:
This little 80 mm marvel from Noctua isn’t just a fan; it’s a silent guardian for your PC’s precious components. With its Advanced Acoustic Optimisation (AAO) frame and Flow Acceleration Channels, it whisks away heat with a whisper, not a roar. The custom NE-FD1 PWM IC delivers smooth, automatic speed control for ultra-quiet operation at low loads, and the included Low-Noise Adaptor lets you fine-tune the balance of cool and quiet to your build. Under the hood, an SSO2 (Self-Stabilising Oil-Pressure) bearing and robust construction ensure long-term reliability in SFF systems, NAS boxes, home servers, and performance desktops alike.
 
Key Features:
• 80×80×25 mm premium PWM fan optimized for heatsinks, radiators with tight fin spacing, and restricted intakes
• AAO frame with integrated anti-vibration pads; Flow Acceleration Channels reduce turbulence and tonal noise
• SSO2 bearing for outstanding longevity and ultra-smooth acoustics
• NE-FD1 PWM IC with Smooth Commutation Drive for quieter low-speed operation
• Wide control range: up to 2200 RPM (1750 RPM with L.N.A.) and near-silent idle at low duty cycles
• Class-leading acoustics: just 17.7 dB(A) max (13.8 dB(A) with L.N.A.)
(Note: Official spec minimum is low-RPM operation, not a guaranteed 0-RPM stop.)
