## Long description

be quiet! Shadow Wings 2 140mm PWM is a 140 mm case fan designed for quiet system cooling. With a maximum rotational speed of 900 RPM and airflow up to 85 m³/h, it delivers steady ventilation for PC cases and components. The fan uses a rifle bearing for reliable operation and comes in black finish. It operates within a 6–12 V range and provides moderate static pressure of 0.58 mmH2O, making it suitable for general case airflow and component cooling.
Advantages
The Shadow Wings 2 combines very low noise levels with solid cooling performance at low revolutions per minute. Its rifle bearing ensures durable, reliable operation while the 140 mm size balances airflow and quiet operation. The fan’s design and specifications make it suitable for builds prioritising silence without sacrificing adequate ventilation.
Suitable for
 Silent or low-noise PC builds
 Case ventilation for mid-tower and full-tower enclosures
 Supplementary cooling for components such as drives and VRMs
 Systems that use PWM fan control for automatic speed adjustment
When it may not be suitable
This fan’s maximum speed of 900 RPM and moderate static pressure (0.58 mmH2O) mean it may not provide sufficient airflow for high-restriction environments, such as dense radiator fins or heavily dust-filtered intakes, where higher-pressure or higher-speed fans are typically preferred. It is intended primarily for quiet case ventilation rather than extreme cooling demands.
Key specifications
 Fan diameter: 140 mm
 Maximum rotational speed: 900 RPM
 Airflow: up to 85 m³/h
 Static pressure: 0.58 mmH2O
 Bearing type: rifle bearing
 Operating voltage range: 6–12 V
 Colour: black
 Weight: 0.175 kg
How to use
Install the fan in the desired case position using the mounting holes provided, aligning airflow direction as required for intake or exhaust. Connect the fan to a PWM-capable header on the motherboard or to a compatible fan controller to enable automatic speed regulation. Ensure the operating voltage is within 6–12 V and secure cabling to avoid interference with other components.
What to consider before purchase
 Confirm available fan mounting points and clearances for a 140 mm fan in your case.
 Check that your motherboard or fan controller supports PWM control for automatic speed adjustment.
 Assess whether 900 RPM and 0.58 mmH2O static pressure meet the cooling needs of your components or radiators.
Usage recommendations
Use the Shadow Wings 2 as intake or exhaust fans in quiet builds and combine with dust filters if needed. For radiator or high-restriction setups, consider higher static pressure fans or additional fans to maintain required cooling performance.
