1 x CPU Fan connector(s) (1 x 4 -pin)
2 x Chassis Fan connector(s) (2 x 4 -pin)

You can use splitters but no more than 2 fans per header.

or use one of these which is much neater and you can use up to 11 fans of PWM header.:

2 case fans + CPU fan. If you get a couple fan header splitters, you can run up to 4 case fans.
