Not sure what you mean by venting the garage? I have attic insulation and it's just plain hot in my garage by the afternoon. My understanding of the attic fan is that it sucks in outside air (much cooler than my garage) from the eves of my house and vents it out the roof. The OP said his new attic fan made a bid difference in the garage temperature. I guess I will find out in a few hours.
