Case: Empire Gaming Warfare PC Case

I bought parts for my gaming pc and started putting it together, i was going well that my fans had a weird 3 pin connecter and a molex attached to them(First PC build so i might be an idiot don’t judge me). I also have a Asus Prime B450M-A motherboard. As it’s micro atx, it has only 2 fan spots, and my case has 3 fans. My case also has only 4 pin slots. My question is, do i need to buy a y splitter to 4 pin adapter for the fans? and where do i plug the molex into?

3-pin and 4-pin fan connectors are interchangeable, so you can plug 3pins into 4pins. The molex is connects directly to the power supply, normally at less than 100% power. (This cannot be controlled). You would need to get a y splitter to control all the fans, but it does not have to adapt.
