Not sure what you mean by "efficient", normally that would mean moving the same amount of air with less power, or moving 
more air with the same power, as well as how efficient the motor is, in other words how much of the energy input moves air 
and how much is turned into heat.

But, using fans that move more air, without regard to how "efficiently" they do so, can't hurt. The more heat you can remove 
from the case interior the better.

Just adding more fans is not the whole matter though, the case has to have a good design, with careful thought to the 
airflow inside it. Just adding fans willy-nilly might even make things worse. I've seen systems put together by amateurs 
where one fan was fighting another, kind of an isometric exercise in sucking up power and doing nothing.
