Premium quality coolilng fan from one of the best known electronic manufacturers in the world, Delta Electronics, this 92 x 92 x 25mm PWM coolilng fan will give you lots of cooling power when you need it. A Superflo bearing design is in place for exceptional duarbility and performance. Fan speed is 3800 RPM with corresponding air flow of 68 CFM (1.920 M³/Min, and noise level of 45 dBA, while the air pressure is 7.67 mm-H2O or 0.302 in-H2O. Rated voltage is 12VDC, and operating voltage is 10.8 to 13.2VDC. Input power is 0.38A at 4.56W. Safety measure includes locked rotor protection where impedance of motor winding protects motor from fire in 96 hours of locked rotor condition at the rated voltage. Over Current Protection will shut down the current when rotor is locked. Fan will be at its maximum speed of 3800 RPM at 100% duty cycle, at 1950 RPM at 50% duty cycle, or at minimum speed of 500 RPM at 0% duty cycle. The frequency for control signal of the fan will be able to accept 30HZ
