Where to connect the fan cables to?

[tuesday0180]

I'm trying to attach a fan in the front of the computer blowing toward the back. I don't see any place to connect the fan to.

Should the fan cord connect to the motherboard? If so, how would I know which socket is the correct one to connect to?

I'm currently using old case fans from old computers to put into my new one.

My new computer only has a rear exhaust fan. I don't have any intake fans.

Wait nm, just read an article saying I can get some converters that allow me to connect the fans to the power supply molex.
