Be quiet!, the market leader of power supplies in Germany for eight consecutive years*, expands its entry level fan series Pure Wings 2 by a 80 mm and a 92 mm model.
With the Pure Wings 2 fan series, be quiet! has set a new standard for the price-performance-ratio of PC case fans. Now the brand presents two new members of the successful series.

The new models are equipped with seven silence-optimized fan blades and high airflow capabilities while reducing noise-generating turbulences and increasing air pressure. The 92 mm model produces a maximum of 18.6 dB(A), while the 80 mm model produces a maximum of 18.2 dB(A) at top speed. High quality rifle bearings guarantee a very long lifespan of 80,000 hours, which is more than nine years. These attributes make even the smallest Pure Wings 2 fan a perfect fit for both home and office PCs as well as demanding gaming and multimedia builds. The new Pure Wings 2 models are especially recommended for the use in air cooling setups.
