be quiet! Pure Wings 3 140mm PWM | Silent Performance Cooling

The be quiet! Pure Wings 3 140mm PWM high-speed Computer case Fan 14 cm Black 1 pc(s) delivers exceptional airflow with minimal noise, making it ideal for high-performance PC builds that demand both cooling efficiency and quiet operation.

Specification Overview

Advanced PWM Speed Control for Optimal Cooling

The Pure Wings 3 features PWM (Pulse Width Modulation) support, allowing your motherboard to dynamically adjust fan speed based on system temperature. This intelligent control means the fan runs at lower speeds during light workloads for silent operation, then ramps up automatically when your system needs maximum cooling during intense gaming or rendering tasks.

Rifle Bearing Technology for Quiet Longevity

Equipped with a precision rifle bearing, this fan offers smooth, quiet rotation that minimises vibration and wear. The 80,000-hour MTBF rating means you can expect years of reliable service without the need for replacement. The bearing design also contributes to the impressively low 30.5 dB noise level at maximum speed, ensuring your system remains whisper-quiet even under heavy load.

High Airflow Performance Where It Matters

With a maximum airflow of 122.6 m³/h and an air pressure of 2.44 mmH2O, this 140mm fan moves substantial volumes of air through your case. The high-speed capability of up to 1800 RPM provides the cooling power needed for demanding components like high-end CPUs and GPUs, while the optimised blade design maintains efficiency across all speed ranges.

Elegant Black Design with Iconic Branding

The Pure Wings 3 features be quiet!’s signature black design that immediately identifies it as a premium cooling component. The sleek aesthetic complements any build, whether you’re creating a minimalist workstation or a showpiece gaming rig. The fan’s design isn’t just about looks—the carefully engineered blade geometry maximises airflow while minimising turbulence and noise.
