If you read at that link you'll see that straightening it isn't a good option. Now fatigue has set up, just waiting for another failure. Comparing the cost of a fan blade to a radiator, no contest.
An electric fan won't necessarily pull more air, depends on size, rpm & blade pitch. An electric fan offers slighty cheaper operating cost, not enough to notice though.
