Manufacturer description
The be quiet! Silent Wings 4 140mm PWM fan is built for builders who want airflow without fan noise dominating the room. Its optimized blade profile is tuned for restrictive surfaces — radiator fins and dense heat sink stacks — where generic case fans stall out. A small tip clearance paired with a funnel-shaped air outlet in the frame concentrates static pressure, so air actually pushes through the fin stack instead of spilling around it. A three-position speed switch lets you pick medium, high, or ultra-high maximum PWM speed up to 2400 RPM, so the same fan can run near-silent in a quiet…

Frequently Asked Questions
How fast does the Silent Wings 4 140mm spin?
Up to 2400 RPM on the ultra-high setting. A physical speed switch also offers medium-speed and high-speed maximums, so you can cap the PWM ceiling lower for quieter operation.
Is this fan good for a radiator or just case airflow?
Both. The blades are optimized for radiators and heat sinks, and the fan ships with individual mounting systems for case-fan or radiator use. Small tip clearance and a funnel-shaped outlet raise static pressure through fin stacks.
Is the Silent Wings 4 actually quiet?
be quiet! describes it as virtually inaudible at regular speed. The 6-pole motor and fluid-dynamic bearing limit vibration. Running the ultra-high 2400 RPM setting will be louder than the medium-speed cap.
What warranty comes with the BL119?
be quiet! includes a 5-year manufacturer warranty. Check the product listing for current registration or claim terms in your region.
