Runs at lowest speed when no PWM function being used.

NOTE: PWM Fans are not variable speed control fans on their own.  An integrated circuit varies the speed and airflow of a fan using a pulse-width-modulated (PWM) voltage in response to temperature or system commands send typically by a computer motherboard. You can use them to run at full speed from an external supply if you adapt the plug.
