be quiet! Silent Wings 4 140 mm PWM HS – Ultra-Quiet Case Fan with Hybrid Bearing

The be quiet! Silent Wings 4 140 mm PWM HS is a high-performance case fan engineered for silent operation in PC enclosures. It combines a 140 mm blade diameter with a hybrid bearing system to deliver consistent airflow at minimal noise.

• 140 mm blade diameter moves large volumes of air efficiently across CPU and GPU heatsinks
• Hybrid bearing design reduces friction and extends operational lifespan
• 4-pin PWM connector enables precise speed control by the motherboard
• 12 V operating voltage ensures compatibility with standard ATX power supplies

Das zeichnet den Silent Wings 4 aus

The fan's 140 mm frame size is optimized for modern mid-tower and full-tower cases that support larger airflow paths. The PWM control allows the motherboard to adjust rotational speed dynamically based on thermal load, keeping noise levels low during idle and light workloads.

Ideal für...

Users building or upgrading a quiet PC setup — particularly those who prioritize low acoustic output in a home office or living room environment. The 140 mm form factor suits mid-tower cases with 140 mm fan mounts, such as many ATX and EATX chassis from be quiet!, Fractal Design, or Corsair.

Mount the fan in a rear exhaust or front intake position on a compatible 140 mm fan mount. Connect the 4-pin PWM header to the motherboard's CPU_FAN or SYS_FAN connector. The fan operates at 12 V and draws approximately 0.397 W of power, making it suitable for continuous 24/7 operation without placing significant load on the PSU.
