I have 9 or10 roof box vents on the backside of the house (1240 sqft), we have a gable fan at one end and is set at 100 degrees. It does a very poor job removing the hot air in the attic. I was told the roof vents are useless since the fan only ***** air from the first two or three vents closes to the fan. He told me to cut 12" square pieces of plywood and cover those vent holes up so the gable fan pulls air thru the attic...it makes sense, what say you?
