Hi. I have used my STF 8300 for many years with no problems. Recently the fan began to slow down and has now stopped entirely. The cooling seems to work fine, as the camera will cool a good 25C from ambient initially, but with no help from the fan begins to heat up again considerably. I removed the fan to see if there was any blockage (no, it turns easily) and the red and black cables to the motor appear to be in good shape and solidly connected. Any suggestions? Thanks
