I've been running a Mitsubishi projector now for a little over a year. I don't recall the model number offhand but as a somewhat general question, do you guys know if there are significant differences between the sound generated from different projectors whether fan noise or whatever? I would say that during some movies when the scene is fairly quiet, the projector fan is fairly noticeable and at times I feel quite annoying.Any overall thoughts?I was also wondering if anyone has devised some sort of device to mount underneath the unit to at least cut down on the noise that can be heard directly below. The projector is mounted on the ceiling. Due to the room set up centrally above the listening area, sofa. I thought that there must be some sort of device out there aside from building a wood platform around the side and bottom of the projector?
