If its super super super annoying and you have the time to play with things you could try a couple tests.
1. Access the fan wires and power it from a 12v battery. Or a 12v power supply. To isolate it from everything.

Maybe at a certain RPM it's matching the harmonic frequency of the roof structure components? Very annoying and sure would like to fix it. Maybe the fan motors could be isolated with some type of rubber mounts?? Have no idea what these things look like inside.
