This tells you it's not wheel bearings or anything related to the 
final drive. It could be something in the engine, but it could just 
as easily be elsewhere and something that happens to resonate with 
the frequencies the engine creates at that rpm.

You happened to mention the fan and we've all focused on that part, 
but this is probably a red herring. Move around the car while someone 
else holds the engine at this rpm. It could be engine tin, but it 
could just as easily be a loose knob on the popout windows. I doubt 
if it's actually the fan or anything to do with welding or balancing 
it.

Since opening the engine seems to make the sound go away, consider 
the rear door and the engine cover. Both of these can develop 
loosenesses.
