My DCS-6620G is consistently failing after a few moments of being turned on. I realized it was overheating and when I opened the camera the fan was not working. The fan blade turns fine and is connected to the board. To test that the internal fan was the issue, while I had the camera open I used an external fan to blow cool air across the boards and the camera worked fine. Not sure if the fan failed or if there is a sensor failure. Any direction would be great.
