Any way to control fans that only have molex power?

[Goose]

I just bought an Antec case that comes with 6 rgb fans that are, disappointingly, daisy chained together with molex connectors. Since I can’t connect them to the motherboard is there any other way to control the RPMs and the RGB?

Thanks

I still have resistor cables that were common when molex fans were, but usually you would use a fan controller.

Which case is it?

Antec CX700

I ended up doing the sensible thing and bought some decent PWM fans to replace them.
