What is the audio quality like?
hehe i am sure dirk have the microphone disabled.

You can solve that by placing a chimney over the side vents, if you can make it 10cm or more tall and restrict the size of the top a little so that it fills up with warm low density air then it should work quite well to suck air through the camera even without the fan...What surprising is, that there are no vent holes on the top of the camera, since the hot air goes up by nature...
That might work if you have one chimney pointing up (for warm air to go out) and one pointing down (for cold air to come in.) Or just a chimney on one side.You can solve that by placing a chimney over the side vents, if you can make it 10cm or more tall and restrict the size of the top a little so that it fills up with warm low density air then it should work quite well to suck air through the camera even without the fan...
You can get your ultrasonic transducer to actually pump if you arrange it right:That might work if you have one chimney pointing up (for warm air to go out) and one pointing down (for cold air to come in.) Or just a chimney on one side.
Strong emphasis on might. I think the restriction would cause more harm than good. Possibly worth testing though.
I had an idea for PC heatsinks that I never got round to testing. If you point an ultrasonic transducer at a heatsink, it will move air backwards and forwards rapidly over the surface. That might improve conduction of heat from the surface to the air since fresh molecules are constantly being put in contact. Again - might!
True, but the warmer electronics run, the sooner they fail. They don't have to be hot to the touch for this to come into play.
