Hi, Well after spending a fair amount of time watching my new projector I noticed that since ceiling mounting the projector I am suffering from the fan blower effect. The results of my tests show that the room temperature needs to be <= 20 deg C or else it spins up about every 20 mins. It does not however seem to suffer if on a table. It seems that the rising warm air collecting at the ceiling is enough to trigger the fan. Has anyone got any clarification on getting a newer firmware update to prevent this. I would sacrifice lamp life as a result if it not likely to bust any other components. Any thoughts, Nick.
