Thanks for the reply. Mine isn't whining from the motor, never has anyway. It's the airflow path/restriction/pressure causing the sound. I was going to try an external blower (higher CFM) with a larger fan that spins at a slower RPM. That along with the requisite ducting I hoped would allow for less pressure, more flow and much less noise. I just never got around to trying it. Maybe one of your guys could give it a shot?
