The Be Quiet! BL109 Pure Wings 3 140mm PWM High-Speed Fan is a high-quality computer case fan designed for maximum airflow volume of 72.2 CFM. With a maximum fan speed of 1800 RPM and a fan diameter of 140mm, this fan is both powerful and efficient. The fan is made of durable plastic material in a sleek black colour. I have bought and use a number of these for my PC and this was one more I didn’t need. This fan is a reliable choice for great cooling and ventilation needs.
