   Hi All,   
      
   Neighbor called me over to look at his new swamp cooler as the motor is making   
   a lot of noise. We took the fan belt off and the noise level didn't change at   
   either speed. It's a loud humming droning noise that seems to be about the   
   resonant frequency of    
   drywall-walls as we can hear it throughout the house.   
      
   We mounted the entire cooler on strips of foam rubber so nothing is touching   
   any thing solid to transmit the noise. Still it persists unabated.   
      
   Is there any point in pulling the motor apart and seeing of we can make it hum   
   less?   
      
   If so, what would we be looking for?
