In my ongoing battle to improve attic ventilation to reduce temps and improve A/C performance I decided to install dual powered attic fans. I let the roofer who installed our last roof talk me into ditching our attic fan and go with ridge vents. Bad idea - they're terrible. Will be sealing up the gable vent to the right of the fans and much of the ridge vents with spray foam. I anticipate much cooler attic temps this summer!
