Ok, aftertalking to Bill He sent me out a new fan. I looked up the model # of both fans online. The old fans are 101 CFM (cubic feet per minute) the new ones are 140 CFM (more airflow, I also purchased a case fan from radio shack as a spare, 85 cfm. So now the experiment is on, more flavor with slower fan? Better smoke ring with higer fan? we will see!
