Be Quiet! PURE WINGS 3 140mm PWM High-Speed Case Fan, Rifle Bearing, Newly Designed Fan Blades And Re-Arranged Angle For Extraordinary Air Pressure, 3 Years Warranty

Pure Wings 3 140mm PWM High-Speed – Performant, Progressive, Quiet

Pure Wings 3 140mm PWM high-speed fans are designed for demanding PCs that require extraordinarily high performance, progressive technology, and quiet operation. With a speed‑regulating closed loop motor and optimized fan design, they deliver reliable, consistent cooling even under resistance.

Key Features

• Closed loop motor maintains the target rpm regardless of air resistance
• Optimized fan frame for outstanding performance on radiators
• Newly designed fan blades and angles for extraordinary air pressure
• Very low minimum rpm for exceptionally quiet operation
• Long-life rifle bearing with an operating lifetime of 80,000 hours
• Product conception, design and quality control in Germany

Innovative Closed Loop Motor Technology

Persistent RPM – Comparable to Cruise Control

Pure Wings 3 140mm PWM high-speed features an innovative closed loop motor. Similar to cruise control in cars, this technology continuously monitors fan speed and compensates for resistance, such as fan grills or radiators, which would normally slow the fan down.

• Constantly monitors current rpm
• Increases speed automatically to reach the target rpm when needed
• Ensures the fan always operates at the desired speed, no matter the air resistance

Optimized Design for Maximum Air Pressure

Enhanced Frame and Blade Geometry

The fan frame outlet is newly designed to minimize air leaks, which particularly benefits radiator performance. To push performance even further, the fan blades are also optimized:

• Newly shaped outlet reduces air loss
• Adjusted blade angle increases air pressure
• Delivers unprecedented air pressure performance in its class

Made for Radiators and Heatsinks

High Pressure Fan Blades

With a remarkably high air pressure of up to 2.44 mm H₂O, Pure Wings 3 140mm PWM high-speed is an excellent choice for both water-cooled and air-cooled systems.

• Air pressure: up to 2.44 mm H₂O
• 9 airflow-optimized fan blades
• Designed to perform reliably even in demanding configurations

Iconic, Functional Design

Streamlined and Timeless
