Be Quiet! also unveiled the third-generation of its flagship low-noise fan series, the Silent Wings 3. So much R&D has gone into making these fans low-noise, that the company is claiming them to be "virtually inaudible." Available in 120 mm and 140 mm sizes, the fans take in 4-pin PWM power input, cost-effective variants come with 3-pin inputs, and preset voltage adapters. Design improvements include a new refined rubberized frame that's air-flow optimized, a newer copper-core FDB bearing, a 6-pole motor, and vibration-dampening mounts. The company will sell these in several SKUs based on size and power input type; and part of its upcoming CPU cooler packages.
