Most folks would go to a higher temp thermostat rather than a lower temp. By keeping the coolant cooler, more energy is wasted to warming the coolant which will lower you efficiency.

On my Maxima I have the grille nearly completely blocked off which decreases the warmup times, and I have yet to have a problem with it overheating. The ideal internal combustion engine would have extremely high operating temperatures, but modern technology isn't quite there yet. So we have to deal with the lower temperatures of around 195*
