Is heat transfer and room heating better with a low or high speed fan?

We have a clean burning wood stove that does a great job at heating the house. We have an oscillating "tower" style fan behind it in the corner of the room.
As the wood stove heats the air around it, the air immediately next to it gets very hot. Lets say 140 degrees. As you travel farther from the stove, the air is cooler.
Is it better to run the fan on low and blow a lower volume of very hot air into the room, or is it better to run it on medium or high to move a higher volume of "less warm" air (because of less time in close proximity to the stove)?
These numbers are only used for illustration.
Is it better to move air at 140 degrees at 500 CFM or...
Is it better to move air at 100 degrees at 1000/1500 etc. CFM?
My question is specific to the fan spreading the heat out by blowing hot air, not on the energy consumption of the fan itself.
