As per your mobo's image here, you have;
2x CPU fan headers
3x Chassis fan headers
1x Power Fan header
all of which can be controlled via BIOS. For the chassis you can have 4 fans to hook upto the mobo.
You may run your fans off the mobo's header or have them run off molex plugs. The advantage with the mobo header is that they can be manipulated in BIOS but with molex connections the fans are at full speed. Good for airflow but bad for the constant hammering on your ears so the former is a better option if you prefer a quieter setup.
