Legendary silence, epic performance and features For the highest performance, optimized fan blades, especially for heat sinks designed radiator corners and a speed switch with 3 selectable speed options, Silent Wings Pro 4 140mm PWM is the most progressive, performant, and versatile fan by be quiet!
Optimized fan blades for the highest performance on radiators and heat sinks
Speed switch allows changing maximum PWM speed between medium-speed, high-speed and ultra-high-speed (up to 2400 rpm)
Small tip clearance and a fan frame with a funnel-shaped air outlet for extremely high air pressure
Virtually inaudible operation at regular speed
6-pole fan motor for less vibration and power consumption
Fluid-dynamic bearing enables very smooth operation
Individual and easy mounting systems for use as a case fan or with a radiator
Super-long life-span of up to 300,000h
Valuable sleeved PWM cable and easy to install PWM connector
Elegant look with high-grade fan sticker in an all-black design
