he Nidec R80W12BS3M9 is an exceptionally powerful 80x80x56mm, 12V DC axial fan designed for extreme cooling demands. It features an incredibly high 16,000 RPM speed, delivering an outstanding 137.5 CFM of airflow and an impressive 7.09 In H₂O of static pressure, making it highly effective for cooling components within highly restrictive or densely packed enclosures. Despite its high noise output (82.5 dB(A)) commensurate with its performance, it utilizes durable ball bearings for a 70,000-hour lifespan, includes PWM control and tachometer output for precise management, and is built with robust materials and protection features for reliable operation in demanding environments
