Why do fans have an odd number of blades? I have a couple with 3, 7& 11. Any reason why they would use odd numbers?
I know we have a Cases and Cooling forum and God for bid Off Topic
but this seems like place to get an answer other than "Uhh, they had an extra fin and needed to put it on something"
The question stems from my aquiring a fan (11 blades) that has a damaged blade and I was going to remove it and it's "opposite" for balance but there isn't one if there is an odd number
Thanks,
