I recently bought an Epson 5650 projector and is very happy with the picture and noise when the projector is in Eco mode placed on a table. After some time I mounted my projector in the ceiling, and it seems for some reason the fan speeds up when the projector is set in "ceiling" projection mode. I have found other people with the same issue, but my questions - is this normal for everyone? Is there a way stop this from happening (e.g service menu)? I have never seen such behavior on a projector before, so I was very surprised to see this. I was actually considering adding a resistor to the fan to slow it down, if I do so does anyone know what will the impact be, just shorter lamp hours or will I burn the LCD's? I don't get why ceiling mount should require more cooling!? Maybe I have to hang up a small shelf on the wall where it can be on "normal" mode... Thanks!
