QFR0912VH-SP00 is a DC brushless axial flow fan designed for thermal management applications with single-phase, four-pole motor architecture. The fan operates at a rated voltage of 12 VDC (10.8–13.2 VDC operational range) with a maximum input current of 0.60 A and input power of 7.20 W maximum, delivering a maximum air flow of 2.117 m³/min (74.78 CFM) at zero static pressure and maximum air pressure of 8.62 mmH2O at zero air flow. It features PWM speed control capability (30–300 kHz frequency range, 25 kHz preferred) with an open-collector frequency generator output for rotor speed monitoring, and operates at 4200 RPM nominal speed with acoustic noise averaging 45.0 dB-A. The fan is equipped with two ball bearings, plastic frame and impeller (UL 94V-0 rated), and offers 70,000 hours continuous operation life expectancy at 40°C, making it suitable for server cooling, industrial equipment, and thermal management systems requiring reliable, controllable airflow.
