Why does your optima dv10 projector overheat even fan is running?

The Optoma DV10 projector may overheat even when the fan is running due to several potential issues. Dust accumulation in the vents or filters can obstruct airflow, reducing cooling efficiency. Additionally, if the internal components are malfunctioning or if the ambient temperature is too high, it can lead to overheating. Lastly, prolonged use without adequate breaks can also contribute to excessive heat buildup.
