I don't think that's really correct. I have had the Solar Guys garage fan for 13 years now and it's one of the best things I could have done. The garage indeed does pull in the outside air, but that's much cooler than the built-up heat that would develop. Plus the attic gets vented which helps cool the entire house a bit. Last, the garage is in the shade and the heat doesn't build up. My garage actually feels cooler than outside.
