How Does PWM Technology Improve Cooling Efficiency in Fan Controllers?
PWM technology improves cooling efficiency in fan controllers by adjusting the fan speed based on temperature needs. PWM stands for Pulse Width Modulation. This technique controls the power delivered to the fan by rapidly turning it on and off. The ratio of on time to off time determines the fan speed.
When the system requires cooling, the fan operates at a higher speed, moving more air. As temperatures decrease, PWM reduces the fan speed, lowering airflow. This dynamic adjustment enhances cooling performance while minimizing noise.
PWM also enables energy savings. By running the fan at lower speeds during cooler periods, the system consumes less power. This reduces strain on both the fan and the overall power supply.
In summary, PWM technology provides precise control over fan speed. It enhances cooling efficiency and reduces noise and energy consumption in fan controllers.
