I thought ridge vents were all the rage these days. I installed ridge vents and then put up Reflectix Reflective Roll Insulation from the soffits up to 12-18 inches from the ridge. It reduced the heat in the attic by a noticeable amount and wasn’t too expensive or difficult to install. I also blew in additional insulation. I plan on adding additional venting in the soffits in the future. My experience is that fans fail, require maintenance, use energy, and tend to only cool the attic off in certain areas if not well planned out with supporting architecture and venting.
