I'm new to printing, I've only made some 10mm test cubes. How does the air blowing onto the print help the process?

I have a dual extruder i3 Pro C. It seems like my fan only cools the back of the two motors. .....

regarding to i3 Pro C,the fan mounted to extruder is for cooling extruder .so it could not used to cool printer.

Is the fan very efficient for cooling the extruders if it's mounted at the back of the motor?

Also, at what point during the print process should the fan cool? Is it off and on to regulate the extruder tamp as needed?
