be quiet! ships SilentWings 2 PWM fans

Posted on Tuesday, December 04 2012 @ 15:42:06 CET by

German cooling firm be quiet! introduces a PWM variant of its SilentWings 2 fans. This new line of silent case fans is available in 80mm, 92mm, 120mm and 140mm sizes. The SilentWings 2 series uses fluid dynamic bearing (FDB) and promises a super-long life of 300,000 hours. The SilentWings 2 PWM fans will be available this month, prices range from 19EUR for the 80mm to 23EUR for the 140mm variant.
The SilentWings 2 fan from be quiet! has earned high praise from both professional product reviewers and consumers, making it clearly a market favorite. SilentWings 2 uses the most advanced bearing technology on the market called fluid dynamic bearing (FDB). The bearing essentially has the fan float on a cushion of fluid, resulting in extremely low noise levels because there is virtually no friction to create sound. When coupled with the unique aerodynamic fan blade design be quiet! is famous for, SilentWings 2 is virtually inaudible.

"We are really happy to announce this product is shipping now since we've had so many requests from the marketplace to add this functionality to SilentWings 2. We wanted to make it right, and ensure that the PWM models are true SilentWings 2 through and through." said Scott Richards, Global Brand Director at be quiet!.

PWM, short for pulse width modulation, is the preferred standard for those who want their PC case fans always to run at the best ratio between performance and quietness. There is no need for hardware fan controllers since the fan is automatically controlled by the computer BIOS. Silent Wings2 PWM also offers the popular and often copied detachable mounting elements for different scopes of usage. Even the very long expected lifespan of the original SilentWings 2 fans remains unchanged at 300,000 hours.
