HIGH ALTITUDE MODE VS. FAN NOISE
I know JVC projectors have lower thresholds for heat build-up than most other brands (JVC recommends utilizing High Altitude mode at elevations above 3,000 feet). Unfortunately, they're also nosier than most other brands when this mode is activated. I would like to hear the experiences and suggestions of projector-owners in High Altitude regions, to see if they have found a way to compensate for this situation (or whether they simply chose to disregard it, without repercussions).
For instance, would using the JVC projector for nighttime viewing possibly eliminate the need for High Altitude mode, or perhaps during cooler months of the year? What about the idea of hanging a USB fan next to one of the exhaust ports as an alternative to High Altitude mode, to either blow or draw air (and if so, which particular port of the RS540-style projector)? Or could this possibly cause issues with dust build-up or dust blobs? Can High Altitude mode be deactivated occasionally in order to enjoy programming that is equatable with, in Elaine Benes' words, being "sponge-worthy" of the privilege? After all, what's the good of watching "A Quiet Place" when your projector environment is anything but?
I live in the Southwest, at 4,000-feet elevation. I had to remove both my PS3 and Dish Network receiver from my A/V cabinet in order to get them to stop periodically shutting down, presumably due to low air density. I used to keep High Altitude activated on my Sony projector as a precaution (even though its threshold was 5,000 feet), without having significant issues with its fan noise (but its panels failed nevertheless). But the JVC is a whopper; its loud High Altitude fan drowning out a lot of the benefits of having a well- calibrated audio system.
My projector hangs about 6 1/2 inches from my eight-foot ceiling, about two feet behind my seating.
Thank you very much.
