- Page 4 UN-R6900-FAN-S, which has a different prefix and suffix. The R6900-FAN fan module contains two fans. Each fan has a rotor composed of seven vanes at the air inlet and a rotor composed of five vanes at the air outlet. When a fan operates normally, the two rotors are reversed in direction to form counter-rotation for sufficient wind pressure.
- Page 5 Key features Automatic speed adjustment The fan uses pulse width modulation (PWM) to adjust fan speed quickly, accurately, and stably according to system instructions. If the external environment or a system internal component has a high temperature, the fan speed increases to help fast heat dissipation. If the temperature of the external environment drops, the fan speed decreases to save energy.
