An extra fan blade isn't really going to make any difference in cooling. Granted, the blade is designed similar.
If the 5 blade fan has slightly more pitch than the 6 blade fan, they will probably move the same amount of air.
A 6 bladed fan is easier to balance though, and make take slightly less amperage to draw the same cfm as a 5 blade fan
