A high-performance, premium 140 mm case fan with PWM control, an integrated mode switch, an advanced 6-pole motor, and a standard 4-pin connector for connecting to the motherboard or specialized hubs. Positioned as a top-tier product aimed at scenarios demanding high static pressure and flexible speed adjustment. The be quiet! Silent Wings Pro 4 140mm PWM fan boasts exceptional versatility, although its design is fully optimized for working in environments with high airflow resistance.
Due to its high static pressure and removable corner mounts, it is perfect for mounting on radiators sized 140, 280, and 420 mm, ensuring effective airflow through dense radiator fins. It can be used as a replacement for stock fans on tower-style super coolers that support 140 mm fans. It will work effectively in computer cases, including slots with dense dust filters. With a mode switch limiting rotational speeds to 1100, 1900, or 2400 RPM, the model is suited for high-load systems. Designed for long-term 24/7 operation. Comes with rubber dampers and a set of pins for tool-free mounting.

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.
