be quiet! is, not surprisingly I'm sure, a company about removing the burden of noise from power hungry, heat-producing, and noisy components that make up the high performance computers of today. They brand themselves as a "premium manufacturer," and our first impressions of their Silent Wings 2 fans didn't leave us questioning that. The Silent Wings 2 promise quality construction and components and thoughtful design to deliver a fucntional case fan that moves plenty of air but is, for all intensive purposes, silent. And boy, are these a treat for tired ears.
The SilentWings 2 fan family provides the greatest airflow-to-noise ratio and highest reliability on the market. Key to these fans’ unrivalled and uncompromising performance are a unique airflow-optimized fan blade design, custom anti-vibration mounts, and a high-tech fluid dynamic bearing with copper core that greatly reduces noise and imparts super-long life. Through this advanced technology these fans achieve virtually silent operation without sacrificing airflow, and so offer the perfect balance between superior cooling and serenity.
The SilentWings 2 140mm model is the largest fan we make that combines all of the above class-leading features. It provides maximum cooling airflow and operating noise levels down to a virtually silent 15.8 dB(A).

An understated box gives way to be quiet's premium Silent Wings 2 fan with a neat plastic carton. The two different attach brackets are in a tray that lifts off to reveal the 3-pin to 4-pin Y-connector, a 12V to 7V and 5V adapters for reduced fan speed and lower noise (not sure why you'd need any quieter), as well as 5 rubber mounting push pins and metal screws (YAY for a spare!), and finally 5 silica gel washers for vibration reduction. A pretty exhaustive inclusion list for a case fan, similar to Noctua's premium fans, and we're happy to see these premium fans arriving with a matching premium-level "payload." Alright, let's dig in.
