When I look at the 12v case fans in the market I see some have shorter blades and a large centre core where the wire is wound and some other fans are opposite - meaning that the blades are large and the centre core is small.
My question does it make a difference which way the fan is built regarding....
1. amount of air flow
2. RPM speed
3. lasting quality
4. power usage
