It rotates at 500 to 1,500 revolutions per minute . It transports 29.4 to 47.9 m / h (17.30 - 28.19 cfm) of air and generates a static pressure of 0.78 to 1.16 mm H2O at a maximum volume of 27.5 decibels.The corners of the Frost 12 PWM FRGB are rubberized and prevent vibrations generated by the fan from being transmitted to the housing. This minimizes the background noise. The built-in RGB LEDs in the hub let the milky-white fan blades of the Aerocool fan shine in 16.8 million colors. The fan has a 4-pin PWM connector.Technical details:- Dimensions: 120 x 120 x 25 mm- Material: plastic / rubber- Volume: 18.2 to 27.5 dB (A)- Speed: 500 to 1,500 rpm- Delivery volume: 29.4 to 47.9 m / h (17.30 - 28.19 cfm) - Static pressure: 0.78 to 1.16 mm H2O- Lighting: RGB-LED- Power consumption: 3.36 W.- Amperage: 0.28 A.- Voltage: 12 V- Starting voltage: 6 V- Bearings: plain bearings- MTBF: 40,000 h- Connection: 4-pin PWM
