Do I need 3 pin to molex adapters for my case/mobo?

Hi there! I just ordered all the stuff to build my first PC. I ordered the corsair c70 case that comes with 3 fans and the ASRock H77M Micro ATX LGA1155 Motherboard and I was just wondering if I needed to order any 3-Pin ATX Fan to 4-Pin Molex Connector Cables to connect all my fans?

  1. You dont actually need the adapters, you just plug them onto the 4-pin header, just with 3-pin fans, the mobo won't be able to control them as well
