I have never printed a fan blade before
How is the balance of it?
your cd rom motor to drive it, whats the rpms if your using a controller, or your best guess sense there is a resistance?

The balance strait from the print bed is fairly accurate. If you need to balance it further, you can use a rod and file to remove necessary weight. I'm guessing rpm of the motor is around 2000rpm at 5v. shouldn't have much resistance with low infill percentage and good print quality.
