I have 3 120 mm fans in my case but my motherboard only has 2 sysfan slots. Is it possible to connect the 3rd one directly to the psu? Or is the 3rd fan useless?
 
You can use a fan-molex adapter to connect to psu. This will result in fan being at 100% all the time.

You can get a Y cable for fan to power two fans off of 1 fan slot on motherboard. This will result in a slight decrease in fan speed.

You can get fan controller.
