I know it's an old thread, but maybe I can find some help here. I have an Epson 8350, which I had to place much too close to the rear wall, since I'm really pushing the projection distance. It is about 4 inches from the wall, and unfortunately the air intake is right there on the back of the projector. So I thought about adding one or two 12v rear fans to help the air flow. How should I do this, given my limited space? Should I just make them blow directly on the intake at a minimum distance, or would it be better to have two fans blowing in diagonal one on each side? Any tips would be very very welcome.
