The placement of the cooling fan. And the airflow of the cool and hot air. There are two models of placing the fan. 

First, you can place the cooling fan near the projector exhaust. And whenever your projector puts hot air outside from him. The cooling fan will immediately suck that hot air and put it outside the hush box. Before the hot air spread in the hush box.

And in the second one in the hush box. There will be only two cooling fans inside and there will be vents. For the consistent flow of cool air and hot air inside the projector. No special fan near the projector exhaust. In this type of placement. 

We first let the cool air in. And after that, it will be pulled out by another fan. This type of projector construction is simple for those. Who is making this type of thing for the first time? It will be easy for them. There are lots of great fans you can consider buying.

You don’t need to pay attention to things. With that, you will be able to control. Your cooling fan. When they will be on or off.
