be quiet! PURE WINGS 3 140mm PWM 3-Pack Fans - BL139

be quiet! PURE WINGS 3 140mm PWM 3-Pack is a set of three 140 mm case fans aimed at stable and quiet cooling for gaming and work systems. The size 140 x 140 x 25 mm and airflow up to 57.39 CFM make them suitable for both cases and radiators. The design is entirely in black color, without RGB, for a simpler and “clean” build. With PWM control (4 PIN connector), you can balance between noise and cooling according to the system load.

What you get is a combination of low noise, long life, and decent ability to push air through denser surfaces. At up to 21.9 dBA noise level, the fans remain discreet even in quieter rooms. The maximum static pressure of 0.96 mmH2O and the optimized fan frame are aimed at better performance on radiators or dense mesh panels. The rifle bearing and declared MTBF 80000 hours mean they are designed for long operation in 24/7 machines. With a total power of up to 3.6 W per fan (at 12 V and 0.3 A), the load on the power supply and motherboard remains minimal.

• Set of 3 x 140 mm fans, giving you a ready solution for front/top/rear intake and exhaust in a standard mid or full tower case.
• Size 140 x 140 x 25 mm – the larger diameter compared to 120 mm allows for more air at the same or lower RPM.
• Airflow up to 57.39 CFM / 97.5 m³/h, sufficient for good overall air circulation through the case or radiator.
• Maximum static pressure 0.96 mmH2O ±10%, in combination with the optimized frame for better performance on radiators and denser filters.
• Low noise level of only 21.9 dBA, which helps keep the system quiet even during prolonged gaming or work.
• Rifle bearing type Rifle Bearing and declared 80000 hours of operation for longer life compared to the most basic sleeve solutions.
• 4 PIN PWM connector for precise control of RPM through the motherboard or fan controller and better balance between temperature and noise.
• Operating at 12 V, with up to 0.3 A and 3.6 W per fan, which is well within the standard fan headers.
• Entirely black design without RGB lighting – suitable for clean builds or if you do not want additional cables and software.
• Warranty 36 months, which provides peace of mind for a longer period of use.

Who is this set suitable for? For anyone building a quiet gaming or work machine and wants three identical 140 mm PWM fans – for airflow in the case as well as for AIO or custom water cooling. If you are looking for an RGB show or aggressive look, you will not find it here – this is more of a set for people who care about acoustics and a clean appearance.

The most sensible aspect of this model is the combination of three fans in a set, low noise, and long life, plus the design of the blades and frame that is oriented towards real efficiency rather than flashy lighting.
