As for CFM, i'd say in the 50-70 range. i think that my current fans are running at, or slightly below 50 cfm. i was just trying to find a way to up the airflow a bit while trying something different. i know that the squirrel cage blowers lack a "dead spot" which may help my cooling as well. i have two fans in a push-pull config with shrouds and i was thinking of adding a bit more "juice"
