I've got 31 hours now on my 8350 and love it so far. Last night after watching a couple of movies, I decided to check out the different "color modes" for the first time. I didn't know what it was set on for all of my viewing so far, and turns out it was on "natural" mode. Being happy with that, I was just curious to see what the others look like. I switched to "living room" mode, and as expected the fan got louder with the brighter picture. BUT, when I switched back to "natural," the fan didn't immediately go back to quieter. I waited about 30 seconds to a minute, and it was still running the louder fan. I shrugged it off, and shut the projector down, thinking it'll be back to normal next time I turn it on leaving it on "natural" mode. But of course now it's kind of bugging me.
Every time I've messed with settings before, like between normal and eco lamp modes, the fan always got louder and quieter within 1-2 seconds of changing the setting. I would go turn it on right now and check, but I don't want to turn it on just for a couple of minutes and turn it right back off, and it might be a few days before I watch something with it. Am I worrying for nothing?
