Smoker has 2" of insulation, no air leaks, you guys have guru fans 2.5x as powerful as it needs. Choking the damper does not linearly reduce the amount of air the fan blows. It's real job is to limit air intake when the fan is not cycling. I'm not trying to be a prick but I think you need to try the pit viper fan. The 25cfm fan is for stickburners and very large pits

Finding a way to close down the exhaust will help to keep temps down. When guru'd most insulated vertical owners have the exhaust open only 25% to limit air flow
