How many fans does my motherboard ASUS H-81 M-K Support?

I wanted to know how many cooler fans can i add to my casing? .Currently 1 stock cooler fan is attached to rear. How can add more fans? any special connectors would be required?

If you want to add more case fans, check out a fan controller that mounts in the case's front panel.
Plus, you can always plug them directly into the PSU if you don't mind them always running at full RPM.
