Hey Joseph:

I don't understand how a fan would not be better. Moving 1600 cfm of
super heated air from an attic has got to help. I'll agree it isn't
going to drop the indoor temp 5 deg but moving 1600 (or even 1200
accounting for inefficiencies) has got to be a good thing for at
least the shingles.

Note that I wrote: ".. there is little difference in real results of a
active or passive system..." The difference is just not worth the cost in
reliability (if the fan fails then it is blocking the passive vent) cost of
the fan, power usage, vibration and noise. Yes even a small decrease would
be good, but not enough good to outweigh the cost in most situations.
