Features: 80 x 80 x 25mm (3.15 x 3.15 x 1 inch) | Voltage: 12V | Current: 1.00A | Airflow: 85.2CFM | Power: 12W | Speed: 6500RPM | Connector: 4PIN. Fantastic fan and as loud as any other when speed is controlled. Below 2000 RPM, they push much more air than quiet fans at the same speed without any noticeable difference in noise level. High Speed: This model is designed to maximize airflow and may be too loud at high speeds for some applications. The inverted design of the fan frame makes the air volume more concentrated and the air volume reaches further. The PWM version of the fan is for high efficiency for chassis, radiators and CPU cooling as well as other applications requiring extended PWM for speed control. This fan has high air pressure, allowing for a direct and focused airflow, making them suitable for densely packed radiators. With the addition of ball bearings, a longer lifespan and stability are possible. Brand new and high quality Package includes: 1PC x KZ8025B012U Cooling Fan Specifications: Model: KZ8025B012U Size: 80x80x25MM Voltage: 12V Current: 1.00A Power: 12W Rotational Speed: 6500RPM Air Volume: 85.2CFM Noise Level: 39DBA Operating Environment: -20~50 ° Lifespan: 50000 hours Note: Please allow 0-1cm error due to manual measurement.
