Forcing fan on to cool engine

One of the downsides of grille blocks and hotter thermostats is that your engine is hotter when it is turned off. I've seen many cautions that this can cause the block to crack or other elements in the engine bay to malfunction sooner. So I've been opening my grille blocks and turning the cabin heat up about 1-2 km from home, but this usually doesn't reduce the coolant temp by more than 2-3°C.
I thought that turning the radiator fan on at a low speed would be more effective.
What do you think?
