The be quiet! Silent Wings Pro 4 is a 120mm PWM fan engineered for high-performance cooling applications in PC builds. Its design focuses on generating high static pressure, making it suitable for moving air through restrictive environments such as dense heatsinks and liquid cooling radiators. The fan blades are optimized for this purpose, and the frame features a funnel-shaped air outlet to concentrate airflow. This construction allows the fan to deliver up to 5.31 mmH2O of static pressure for targeted cooling performance.
Fan speed is controlled via a standard 4-pin PWM connector, enabling automatic adjustments based on system temperatures. A physical speed switch is also integrated, providing manual selection of different maximum speed profiles, with a top speed of 3000 RPM. At its maximum rotational speed, the fan is rated to produce an airflow of 83.9 CFM. Internally, a 6-pole motor and a fluid-dynamic bearing (FDB) are used to maintain smooth and low-vibration operation across the fan's speed range.
Key Features:- Standard 120 x 120 x 25 mm frame size
- Variable speed control via a 4-pin PWM connector
- Manual switch to select maximum speed modes
- Utilizes a fluid-dynamic bearing for operation
- Features a 6-pole motor for reduced vibration
- Includes mounting corners for case and radiator installation
