be quiet! Silent Wings 4 140mm PWM Case Fan – Ultra-Quiet 140mm PWM Cooling
The be quiet! Silent Wings 4 140mm PWM HS is a high-performance case fan engineered for silent operation in PC builds. It combines a 140mm blade design with PWM speed control to deliver efficient airflow while keeping noise levels to a minimum.
140mm fan dimension provides strong static pressure and airflow for effective case ventilation
PWM (4-Pin) interface enables automatic speed regulation based on system temperature
12V operating voltage ensures compatibility with standard PC power supplies and fan controllers
29.3 dBA noise level keeps the fan virtually inaudible during typical workloads
Das zeichnet den be quiet! Silent Wings 4 aus
The Silent Wings 4 series is designed for users who prioritize low noise in their PC without sacrificing cooling performance. The 140mm form factor offers a larger surface area than standard 120mm fans, moving more air at lower rotational speeds — which directly contributes to the fan's exceptionally quiet operation.
Ideal für...
Users building or upgrading a quiet PC, particularly in cases with 140mm fan mounts. The fan is well-suited for CPU cooler exhaust, rear case exhaust, or radiator fans in custom water-cooling loops where noise reduction is a priority.
