  6. Circuits Automation Supply Maxim MAX6605 MAX4402 MAX6003,
    Fan noise is becoming a significant issue as electronic equipment increasingly enters the office and the home. Noise is proportional to fan speed, and the airflow hence, fan speed necessary for cooling is less at low ambient temperatures. Because ...
