be quiet! Pure Wings 3 120 mm PWM Reverse Triple Pack Black Computer case Fan 12 cm 3 pc(s)

be quiet! Pure Wings 3 120 mm PWM Reverse Triple Pack Black computer case fans provide quiet airflow for standard ATX and microATX enclosures. Each 120 mm fan is engineered to deliver up to 80 m³/h of airflow while operating at a maximum rotational speed of 1500 RPM. The fans use a rifle bearing designed to balance lifetime and noise performance and accept a supply voltage range of 5–13.2 V. Their black finish integrates unobtrusively into most builds and the PWM control enables dynamic speed adjustment based on system temperature.

Advantages

The Pure Wings 3 fans combine modest maximum air pressure with efficient airflow to cool CPU, GPU and chassis components without producing excessive noise. PWM support allows the motherboard or a fan controller to adjust speed automatically, reducing power consumption and acoustic output when full cooling is not required. The included triple pack offers three identical 120 mm fans for consistent airflow and simplified installation across multiple mounting positions.

Suitable for

• Case intake or exhaust in desktop PC builds
• Replacing or upgrading existing 120 mm case fans
• Standard cooling for mid-tower and small form factor systems
• Systems where balanced cooling and low noise are priorities

Key specifications

• Fan diameter: 120 mm
• Maximum rotational speed: 1500 RPM
• Maximum airflow: 80 m³/h
• Maximum static pressure: 1.17 mmH2O
• Bearing type: Rifle bearing
• Voltage range: 5–13.2 V
• Colour: Black
• Control: PWM (pulse-width modulation)

How to use

Mount each fan in the desired case position using the standard 120 mm screw holes, ensuring the airflow direction matches the intended intake or exhaust orientation. Connect the PWM cable to a compatible 4-pin header on the motherboard or to a PWM fan controller. Verify voltage and connector compatibility before powering the system. After installation, configure fan curves in the BIOS or appropriate software to allow automatic speed adjustment based on temperature sensors.

Usage recommendations

For optimal results, install a combination of intake and exhaust fans to create a steady airflow path through the case. Keep fan dust filters clean to maintain airflow and cooling performance. When replacing older fans, check mounting alignment and cable routing to avoid contact with moving blades.
