I'm on my 2nd RS1, and both the returned one and the new one has unacceptable fan noise. I have two separate and distinct fan noises. The "air-flow" noise I'm hearing is quite loud (in High mode) and this may be normal for the RS1 but I’m guessing is above the 27db advertised (since I can hear it from >15’ away). The other noise I'm hearing (on both units) is a high pitch metallic sound originating from the fan vent area. This may be the same vibration noise that Kevin has isolated. The noise is so annoying that I have to turn the volume up considerably to overcome it. In quite passages it is unbearable! My sitting position is actually 2’ behind the front of the projector, approximately 3’ to the left. The projector is mounted about 3.5” from a 9’ ceiling.
I’m not sure what step to take next. This is obviously a design flaw. I’m in process of designing an acoustical absorption box to surround the unit but air flow and cooling is a major obstacle in doing this. I’m also ordering sound absorption material for the drywall ceiling above the unit since it is mounted only 3.5” from the ceiling and I’m sure some of the noise is bouncing off of the ceiling.
I’m very disappointed in the noise from this unit, but happy with everything else. Has anyone actually talked to JVC about this issue? Does the RS2 use the same fan? If the RS2 fan is quieter, can it be put into the RS1?
This is a ridiculous problem to have for a +$5K projector.
