Maybe by most projector standards it's quiet but it's at least 3x as loud as my htpc and about the same as the xbox. I used to like the quiet hush in my basement but all I hear is that small fan spinning. Anyone built a hush box for it or switched it out with a quieter fan? I've heard of people taking out the stock fans from their CRT projectors all the time and putting in Papst or Panaflo fans and heard a dramatic decrease in noise. Haven't heard of people with dlps or lcds doing this though, are the innards much more fragile? And one more question.. Does everyone else's fan stay on long after the projector has turned off? You have to listen closely but I can hear mine spinnings still.
