Features: brand new and high quality The performance fan PWM version is for ideal for high efficiency for case, radiator and CPU cooling as well as other applications that require both extended performance PWM for speed control. This fan have high air pressure allowing for a direct and focused airflow making them for ideal for the densely packed fin of a radiator. With the addition of the Ball Bearing, a longer lifespan and stability is possible. High Speed: This model is designed to maximize airflow and can be too loud at speed for some applications . The reverse design of fan frame makes the air volume more concentrated and the air volume is farther away. Great fan and just as loud as all the other ones when the speed is controlled. Below 2000 RPM they push much more air than silent fans at the same speed with no noticiable difference sound level. 80 x 80 x 25 mm ( 3.15 x 3.15 x 1 in. ) | Voltage :12V | Current: 0.8A | Airflow: 102CFM | Power: 16.2W | Speed: 5700 RPM | Connector: 4PIN. Specifications: Model: FFB0812EH Size: approx. 80 x80x25mm/3.15x3.15x0.98in Dual ball bearing bearing, high precision Voltage: for DC 12V Current: 0.8A (large air volume fan violence) Power: 16.2 for W Speed: 5700 RPM Air volume: 102.02CFM Working life: 10000 hours Fan interface: 4 PIN Additional features: support speed test Note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
