Product information

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.

Reasons to buy

Whisper-quiet operation for peaceful systems

The Shadow Wings 2 140mm PWM fan features specially optimized blades that deliver strong airflow while keeping noise to a minimum. Even at its maximum speed of 900 RPM the fan runs at just 14.9 dB(A), making it an excellent choice for builds where silence is a priority.

Advanced anti-vibration design

Removable anti-vibration mountings on all four corners reduce vibrations transferred to your PC case. A rubberized frame further dampens resonance to keep mechanical noise and rattling to an absolute minimum for smoother, quieter operation.

Durable rifle bearing for long life

Equipped with high-quality rifle bearing technology, the Shadow Wings 2 140mm PWM is built for reliability and longevity — offering an expected service life of up to 80,000 hours under normal use.

Quick and secure push-pin installation

The included push-pin anti-vibration mounting system enables fast, tool-free installation. Fit the fan securely without screws for a straightforward and time-saving upgrade or replacement.

Intelligent PWM speed control

Pulse Width Modulation (PWM) support lets compatible 4-pin controllers adjust fan speed automatically. That means your system can increase cooling when needed and stay exceptionally quiet during light use.
