be quiet! PURE WINGS 3 140mm PWM high-speed 3-Pack Fans - BL138

be quiet! PURE WINGS 3 140mm PWM high-speed 3-Pack is a set of three 140 mm case fans aimed at more serious gaming and productivity configurations where you want stable airflow. They operate at 400 RPM and are sized 140 x 140 x 25 mm, making them universal for most mid and full tower cases. They offer airflow of up to 72.16 CFM / 122.6 m3/h and static pressure of 2.44 mmH2O, allowing them to push air through denser filters or more closed front panels. They do not have RGB, are black, and look clean in a build that does not chase colorfulness but functionality.

What you get

The three fans with 4 PIN connector give you PWM control, so you can precisely adjust the curves through your motherboard – from quieter operation at idle to more serious cooling under load. The combination of 72.16 CFM airflow and 2.44 mmH2O pressure is good for front intake through dust filters or for push/pull configurations in the case. The motor with innovative closed loop motor keeps the speeds stable regardless of resistance, meaning more predictable behavior and less "playing" with speeds when the filters are dusty or the airflow path is narrower. With rifle bearing and MTBF 80000 hours, you can let them run 24/7 for a long time without worrying about replacement. The noise level of up to 30.5 dBA is reasonable for a 140 mm fan with such airflow.

• Set of 3 x 140 mm fans, which is enough to fill a typical case in the front and back or to upgrade factory fans.
• Size 140 x 140 x 25 mm, suitable for most modern cases with 140 mm slots for better airflow at lower speeds.
• Maximum airflow 72.16 CFM / 122.6 m3/h, providing stable cooling for powerful CPUs and GPUs in closed configurations.
• Static pressure 2.44 mmH2O, which helps when mounting behind dust filters, mesh panels, or denser front panels.
• Noise level up to 30.5 dBA, balancing between cooling and silence for gaming and workstations.
• 4 PIN PWM connector for precise speed control through the motherboard or controller, instead of constant maximum rotation.
• MTBF 80000 hours and rifle bearing for long life during 24/7 operation, backed by 36 months warranty.
• Operating at 12 V, with consumption 5.4 W and 0.44 A, which is completely normal for a quality 140 mm fan.
• Entirely black design without RGB lighting, for minimalist builds or when you do not want a light show.

Who it is suitable for

This set is suitable if you are building a gaming or workstation machine and want to improve the airflow of the case with three identical, controllable PWM fans. It is a good choice for cases with limited airflow, where the combination of airflow and static pressure matters. If you are aiming for a maximum quiet fan setup at very low speeds or mandatory RGB lighting, you are unlikely to find what you are looking for here.

The combination of 140 mm format, stable airflow, and reliable motor with closed loop control makes this 3-pack a practical upgrade when you simply want your case to breathe better and do so for a long time.
