be quiet! Pure Wings 3 Fan 140mm PWM - BL108

be quiet! Pure Wings 3 140mm PWM (BL108) is a 140 mm case fan aimed at quiet and well-ventilated configurations. It operates in the range of 200 to 1200 RPM, giving you a good balance between airflow and low noise. At maximum, it provides a flow rate of 97.5 m³/h with a noise level of only 21.9 dBA, making it suitable for quiet gaming and work machines. The classic black design without RGB makes it ideal for clean, unobtrusive builds.

What you get

As a case fan with a size of 140 x 140 x 25 mm, Pure Wings 3 can cover a larger area than a standard 120 mm fan, which helps for better overall cooling at lower speeds. The PWM 4 PIN connector allows for precise control through the motherboard – the fan can drop to 200 RPM in idle and rise to 1200 RPM only when needed. Maximum static pressure of 0.96 mmH2O is sufficient for front intake through mesh or filters without gasping for air. With a consumption of only 3.6 W (12 V, 0.3 A), it doesn't load the power supply much, even if you put a few of these in the system. The Rifle Bearing bearing is quieter and more durable than standard sleeve solutions, which is a plus for 24/7 operation.

• 140 mm size provides greater airflow at lower speeds compared to 120 mm fans, which helps for a quieter system.
• 200–1200 RPM range allows the fan to be nearly silent at light loads and sufficiently effective at higher loads.
• Flow rate of 97.5 m³/h is more than enough for good airflow in mid-tower cases, both front and back or top.
• Noise level of 21.9 dBA at maximum speeds is suitable for a quiet gaming configuration or workstation in a shared space.
• Static pressure of 0.96 mmH2O helps air pass through dust filters and denser panels without a significant drop in efficiency.
• Rifle Bearing bearing offers a longer lifespan and lower noise compared to standard sleeve, suitable for prolonged use.
• 4 PIN PWM connector allows for automatic speed control through BIOS or software, instead of running constantly at maximum.
• 36 months warranty gives you peace of mind for long-term use in a primary or secondary machine.

Who it is suitable for

This fan is a good choice if you are building a quiet gaming or work configuration and want reliable 140 mm airflow without RGB. It is suitable for front intake, rear exhaust, or top fan in mid and full tower cases. If you are looking for an aggressive look with lighting or extreme speeds for brutal overclock builds, the focus here is more on silence and balance than on effects.

The combination of a wide PWM range, low noise, and good airflow makes be quiet! Pure Wings 3 140mm PWM a stable foundation for a well-ventilated and quiet case. If you need a 'set and forget' fan that just does its job without drama, this model fits perfectly into that role.
