4-pin Molex power input for case fan controller.
Link the fan controller to the MOLEX connector on the power supply.
It really depends on the specific fan controller included with the case. Some models come with a header and cable for RGB motherboard controls, while others don’t. There are also cases with a fan speed header for motherboard management, but some lack these features entirely. I’d bet that the included unit was the least functional—just basic remote or case buttons to adjust it, with no real control over the fans. Additionally, the fans in those cases usually don’t circulate much air.
It's fine to use a SATA to Molex converter since the fans and RGB won't reach the 50W power threshold of SATA power.
