What should I use to power my case fans?
So I have two fans that I'm hooking up in my build, and it's my first build alone, and I don't know if I should hook them up to my psu with molex connectors or to the motherboard. Both of my fans have the molex and motherboard connector. Will hooking them up to the psu have any affects? Like will they run better since it's a straight power supply? If I hook them up to my motherboard will they speed up and slow down according to how hard my systems running?

Normally Case Fans are connected to the Power supply. Since you have the option to connect therm to Power Supply then simply do that.
In the end it really depends on your needs and wishes.If you are ok with the fans running at one specific speed, connect them to your PSU. If you want them to be controlled by your motherboard, connect the fans to your motherboard.

I disagree with Mika, I'd conect them to the mobo.
If its a 3 pin connector it will allow you to measure the fan speed and show its working OK
a 4 pin will let the system control fan speed.
