I recently ran a thread concerning my Sanyo PLV-60 cycling up and down after a couple hours of use. After speaking to a Sanyo rep, I found it was normal for this to happen and that I probably needed to vent the hot air from the projector while providing cool air for the intake.I got a couple of responses to the thread agreeing with that. What I need to know is what should I use to vent the hot air. Are we talking about something like a bathroom exhaust fan, or something else? I did run across exhaust fans that are supposed to be "whisper quiet", but am concerned that it will be too noisy.Is there something else out there I don't know about? Please help.
