Just to clarify I'm really bad when it comes to computers and components. So I wan't to buy new fans for my PC, specifically these: https://www.amazon.com/Corsair-AF120-Quiet-High-Airflow/dp/B00F6S0XJO which you connect with 3-pin. But when I look at the specifications for my motherboard I can't find anything about it having any 3-pin connectors. Sorry if this is a stupid question but as I said I'm pretty bad with computers.
