be quiet! apart from the usual black-colored product, recently announced many "new" white-based products, the Dark Base 701, 901 PC cases, and the Silent Wings 4 / Silent Wings 4 Pro either for 120mm or 140mm formats. These radiant white high-end fans are built for maximum performance in cases, on heat sinks, and radiators, delivering not just great airflow but also high static pressure. The fans feature exchangeable mounting corners to easily adapt the fans to different situations. With the Silent Wings Pro 4 White, be quiet! has turbo-charged its fans to reach extremely high rotational speeds yet offers consumers a choice to configure these fans for low noise, a noise/performance balanced mode, or maximum performance.

Silent Wings 120mm PWM

With the Silent Wings 4 White series, be quiet! has focused on improving static pressure, which is of vital importance when mounting fans to heat sinks or liquid-cooled radiators. The fans feature a low tip clearance of 1.0mm and a funnel-shaped air outlet, dispersing the air over a greater area and resulting in a drastic improvement in static pressure. This makes the Silent Wings 4 White series a top choice for heat sinks or radiators while keeping its noise levels impressively low. Silent Wings 4 White comes with two different mounting corners that are tool-free and easy to exchange: vibration-free rubber push-pin corners and traditional hard-plastic screw-type corners. The fans come in two sizes (120mm/140mm) and two different models: PWM, and PWM high-speed. The PWM models are best suited as case fans with their maximum speeds of 1600 rpm (120mm) and 1100 rpm (140mm), while the PWM high-speed versions are specifically tailored to heat sinks and radiators thanks to their higher speeds of 2500 rpm and 1900 rpm respectively. All Silent Wings 4 White fans rely on a 6-pole fan motor with three phases and fluid-dynamic bearings for a long lifespan of 300.000 hours.

Silent Wings 4 Pro 120mm PWM

For consumers who really want no holds barred, be quiet! is introducing Silent Wings Pro 4 White. While these fans offer the same features as the Silent Wings 4 White, the rotational speed has been turbo-charged to 3000 rpm for the 120mm version, and 2400 rpm for the 140mm version. A speed switch on the back makes it easy for customers who don’t want to deal with PWM fan curves to set the maximum speed based on their preferred usage: Medium for silence-optimized operation, High Speed for a noise/performance-balanced mode, and Ultra High Speed for maximum performance. Silent Wings Pro 4 White includes one additional corner type, specifically created for radiators. These radiator corners form a tight fit on the fan to prevent air leakage and ensure maximum static pressure. The fans also feature a high-grade white mesh sleeve cable and an easy-to-use motherboard connector.
