I have used mobo fan connections in the past coupled with a 2 fan controllers, one that was included with the case, and one that came with the power supply.
I now just use the 2 fan controllers, both take up to 3 fans each, Have 5 fans in total with water cooled setup.
Did have up to 10 fans at one stage with air cooled setup!
