I have kept this 3620 very clean with periodic blowing out of the fan/airflow ducts on at leat a bi-weekly basis. The fan has always operated normally (brief startup of fan upon initial boot, then coming on/shutting off as cooling is needed). Then after sitting unused for approx 1 month (in a clean environment), on power-up the fan comes on and continues to stay on, regardless of temperature (the room can be 65 deg. F and it will continue to run). The PC runs cool to the touch but the fan runs continuously. Any suggestions or links to help me out will be greatly appreciated.
