be quiet! Introduces Silent Wings 4 Fan Series in Black and White, Redefining Silent Cooling Performance
Advanced aerodynamic design and interchangeable mounts cater to diverse PC building needs

October 29, 2025 — German cooling specialist be quiet! has expanded its flagship Silent Wings 4 fan series with dual-color options (black and white) and multiple performance tiers, delivering unparalleled silence and cooling efficiency for high-end PCs. The series combines a refined aerodynamic architecture with modular anti-vibration mounting systems, ensuring compatibility with cases, heatsinks, and radiators while maintaining near-silent operation.

Engineered for Silence and Performance

The Silent Wings 4 series leverages a 6-pole motor with 3-phase technology and fluid dynamic bearings (FDB), reducing vibration and noise while achieving a lifespan of up to 300,000 hours. Key innovations include:

• 1mm blade-gap design: Minimizes air leakage to maximize static pressure, critical for radiator and heatsink applications.
• Funnel-shaped frame: Optimizes airflow direction and pressure, enhancing heat dissipation efficiency.
• Waterwave-pattern blades: The signature 9-curved sickle blades reduce turbulent noise while maintaining high airflow.

Dual Mounting Systems for Flexibility

Each fan includes two interchangeable mounting kits:

1. Pre-installed silicone anti-vibration pins: Ideal for case installations, minimizing resonance.
2. Hard plastic mounts: Designed for secure attachment to radiators or heatsinks.
The snap-on mechanism allows tool-free swaps, simplifying customization.

Multiple Versions and Color Options

The series offers tailored solutions for diverse use cases, available in 120mm and 140mm sizes:

• Standard PWM: Balanced performance (e.g., 120mm: 1,600 RPM, 48.7 CFM, 18.9 dB(A)).
• High-Speed PWM: Enhanced cooling (e.g., 120mm: 2,500 RPM, 76.7 CFM, 31.2 dB(A)).
• Pro 4: Features a physical 3-speed switch (Medium/High/Ultra-High) for manual control, with 120mm models reaching up to 3,000 RPM.

Both black and white color variants cater to minimalist or themed builds, with white models featuring color-matched cables for aesthetic consistency.

Real-World Testing Highlights Superior Acoustics

Independent tests demonstrate the series’ effectiveness:

• In a CPU cooling test with an Intel i7-12700K, Silent Wings 4 fans maintained temperatures below 70°C under load while operating at near-inaudible noise levels (13.6 dB(A) for 140mm models).
• At 1,500 RPM, noise levels blended with ambient sound, outperforming competing fans like Noctua’s NF-A12 in acoustic efficiency.

Pricing and Availability

The Silent Wings 4 series is available globally, with white models priced from $23.9 (≈¥173) for 120mm versions. All variants include a 5-year warranty, underscoring be quiet!’s commitment to durability.
