Answers :

4 pins "PWM" fans are specially designed for use with newer motherboards which have 4-pins CPU fan-connector, but the fans are backwards compatible with 3-pins connectors. Just plug the 4-pins fan-header into a 3-pins connector (only 1 way possible) and you're good to go (although you don't get the "PWM" advantages).
