Re: [APD] Canopy Cooling

You can probably damp that resonance by isolating the fan
with rubber mounts like these:


or by putting rubber washes between the fan and the
mounting surface.

If it is the reflector that is "resonating" to the fan
vibration, sometimes applying a piece of material at the
right location will kill the resonance.
