I did go talk to John who is installing these. We agree to check later in day and see if any comparisons could be made.

John did mine, he's excellent. I really feel with the two fans you should get a noticable drop in temperature. I know after my fans were installed the attic air temperature never goes above roughly 10 degrees over the outside air temperature. For very large attics two of the 35 watt fans should be more than enough air flow. Just check to see if you can see light from some of the soffit vents in the attic. The vents over the garage should be easy to see. Most of them should be open.
Another way to look at it is at the peak of the day if you touch your roof you will burn your hands. The attich should be super heating. Pulling outside air into the attic and pushing out the super heated air has to make a difference.
