Fan be quiet! Pure Wings 3 Fan 120mm PWM - BL105

be quiet! Pure Wings 3 120mm PWM (BL105) is a 120 mm case fan aimed at stable airflow and low noise for normal to more serious gaming or work builds. It operates in a wide range of 200–1600 RPM, giving you flexibility – from almost silent idle to serious cooling under load. At maximum speed, it reaches a noise level of up to 25.5 dBA, which is perfectly fine for quiet systems. The black design without RGB is for those who prioritize functionality and a simple look over lights.

What you get

This fan is designed as a reliable case cooler – for intake or exhaust air. With a thickness of 25 mm and a size of 120 x 120 mm, it fits most modern cases and mounting positions. The airflow of 84.8 m³/h is more than enough to maintain good airflow in a moderately loaded gaming build, especially if you combine several such fans front/back. The maximum pressure of 1.45 mmH2O is useful if you have denser filters or more closed panels where the fan needs to “break through” the resistance. Thanks to the 4-pin PWM connector, your motherboard can dynamically control the speeds – quietly at low temperatures and more aggressively when the CPU and GPU ramp up.

• Size 120 x 120 x 25 mm – the most common standard for case fans, making installation easy in almost any modern PC case.
• Wide range 200–1600 RPM – allows you to balance between silence and cooling according to fan profiles and load.
• Airflow 84.8 m³/h – sufficient for effective overall airflow in the case, especially in combination with one or two more fans.
• Maximum pressure 1.45 mmH2O – suitable for cases with dust filters and more closed fronts, where overcoming resistance is necessary.
• Noise level 25.5 dBA – a good choice if you want a relatively quiet system without a “turbine” sound at higher speeds.
• Rifle Bearing bearing – better durability and smoother operation compared to the most basic sleeve solutions.
• 4-pin PWM connector, 12 V, 0.20 A / 2.4 W – standard power supply and full PWM control through the motherboard or fan controller.
• No RGB, black color – a clean look for builds where you prioritize stealth and minimalism.
• 36 months warranty – a long coverage period for a component that runs continuously.

Who it is suitable for

It is suitable if you are building a quiet or simple gaming/work computer and want a reliable 120 mm fan with PWM control, without RGB and unnecessary effects. It is a good choice for front intake and rear exhaust in mid-tower cases, as well as for upgrading noisy stock fans. If you are aiming for extreme airflow for very hot high-end configurations or absolutely want a light show, you may miss a more aggressive model or RGB here.

The combination of wide RPM range, decent airflow, and low noise, along with PWM control and rifle bearing, makes this fan a practical and balanced choice for stable and quieter airflow in your case.
