I have just received a replacement RS1, the previous projector had problems with the hdmi inputs, they didn't work. Well the hdmi works on this projector but the fan is very loud. The fan on my first RS1 was barely audible form a couple of feet away, but with this new one I can hear it from about 15-20 feet. I checked everything to make sure that I was not in high lamp mode or high altitude mode. And the sound is not just air, it almost sounds like you can hear the gears spinning. Is there any fix that will not void the warranty or require me sticking it in a hush box?
