On my PSU, there are power connections to either the motherboard, CPU/PCI-E, or peripherals. Which do I plug my case fans into? Thanks

Ok so you're trying to provide power to your fans, right?

The fans are supposed to have a 3-pin female connector which plugs into your motherboard.

If you don't have any available / adjacent 3-pin plugs in your motherboard then you also have the option to plug your power supply's molex connectors into your fans (with a 3-pin to molex adapter).

PWM fans have a 4-pin connector and are usually bundled with your cpu heatsink.
Most case fans are not PWM and have a 3-pin connector.

Hope that helped.
