That is good, but seems to be a relatively small upgrade. That would be more for someone that is having a little harder time keeping things cool in a hot climate I think. Also, I am not sure how much a new motor costs for that. Quick math for my upgrade: $19 for the fan, $24 for the relay, $5 for the breaker, and then wiring and connectors that I had, but would probably run $10 if you had to buy them all outright (of course there would be extras laying around afterward), so say $60.
