That's fine that you've done a lot of reading on the AVS threads and other places. My personal experience with the XBR4, like I've said, and I've had it wall mounted and on the stand, I've had no experience with fan noise. Maybe some folks got some faulty units, I don't know. Mine has been flawless since I purchased it. I'm standing with my ear behind the TV as I write this and I hear nothing. NOTHING. No fan noise. Not even a hum. Please leave your obvious subjective comments to yourself. If you've never owned this screen, how can you speak for it?
