Why Does My Cpu Fan Have 2 Cables?

First, any RGB fan has TWO cables from it. One ends in a standard female fan connector with either 3 holes or 4 in it - depends on the fan motor type. This is for the MOTOR of the fan. Then it has a separate cable much wider that ends on a 4-pin connector, OR a 3-pin connector like the 4-pin but with one pin missing.
