Built-in reobas
be quiet! Silent Wings Pro 4 is the flagship series of case fans from a brand from Germany. Represented by two models with a diameter of 12 and 14 cm, both with a 4-pin PWM connection. The cable has a nylon braid, and there is a three-position speed switch on the fan housing. At maximum speed, the noise level is approximately 37 dB.
For tower or dropsy
The distance between the blades and the frame, reduced to a minimum, provides enhanced High-Pressure air pressure. The latter is also achieved by strongly curved blades with aerodynamic grooves. Such fans are well suited for installation on tower coolers or CBO radiators.
Hydrodynamic bearing
The six-pole motor and FDB bearing minimize vibration and extend the life of the fan up to 300,000 hours. There are also Silent Wings 4 fans without the Pro index, devoid of a speed switch, but with more variability: 12 or 14 cm, 3-pin or 4-pin PWM, quiet or High-Speed.
