LEGENDARY SOUND, AMAZING PERFORMANCE AND FEATURES

Silent Wings Pro 4 140mm PWM white a be quiet! the most modern, most powerful and most versatile fan.

- Optimized fan blades for maximum performance on radiators and heatsinks
- Maximum speed adjustable between medium, high and ultra-high speed (up to 2400 rpm) with a speed switch
- Minimal gap between frame and blades and funnel-shaped air intake for extremely high air delivery
- Essentially inaudible operation at average speed
- Thanks to the six-pole motor and fluid bearing design, less vibration and smoother operation
- Different mounting system used as a house fan or radiator

IMPROVED IN EVERY AREA - New generation performance with modified blade layout

Blades make a fan a fan. This is why the Silent Wings Pro 4 140mm PWM white blade design is a completely new development. The new blade arrangement enables unparalleled performance in any operating mode, whether in the case, on a radiator, or on a heatsink.

OPTIMIZED FOR PEAK PERFORMANCE - Minimum distance, maximum air pressure

The Silent Wings Pro 4 140mm PWM white can significantly increase the performance of the system with its particularly large air delivery. This is made possible by the reduced distance between the blades and the frame. As a result, even the most resource-demanding programs can be run with the Silent Wings Pro 4 140mm PWM white fan.

GEAR SWITCH - Three settings for different uses

The speed switch allows you to quickly and easily switch between medium, fast and ultra-fast maximum speed. The white speed of the Silent Wings Pro 4 140mm PWM can be adjusted with a simple slide switch. Medium speed is suitable for any operation that requires average cooling performance. With the high-speed setting, the fan rotates faster, so it cools more strongly. The ultra-fast setting provides enough speed even for high-performance systems that require the most powerful cooling.

SIX-POLE FAN MOTOR - Key to virtually inaudible operation

The 6-pole, three-phase fan motor ensures particularly low consumption, less resonance, and therefore quiet operation, max. At 36.8 decibels. Equipped with the latest technologies, the fan is practically inaudible at medium speed.

THREE DIFFERENT FIXING OPTIONS - Any use

The Silent Wings Pro 4 140mm PWM white comes with three mounting options. The pre-installed radiator corners are specially designed for water cooling, where the performance of this high-end fan shines the most. For indoor use, a mount with a vibration damper is the primary choice, which minimizes noise-causing vibration. The package also includes the plastic fasteners.

FLUID BEARING TECHNOLOGY - Durable operation

The advanced fluid bearing (FDB) technology guarantees a super-long lifespan of up to 300,000 hours, and also reduces resonance and thus supports the Silent Wings Pro 4 140mm PWM white inaudible operation.

ELEGANT APPEARANCE - Paints beautifully in every detail

With its all-white design, this fan fits perfectly into white PCs. Its fabric-covered PWM cable perfectly complements the appearance of the fan. But the PWM cable doesn't just look good: its connector can be easily plugged in and out, so the fan not only looks nice, but is also user-friendly.
