Abstract :
This paper discusses the implementation of pulse width modulation (PWM) fan speed control and how it can decrease energy consumption and reduce acoustics while providing wider operational speed bandwidth. In addition, this paper has described a new high performance PWM fan technology that includes a soft start circuit that monitors current and limits the current intake of a high performance fan
