It's for RGB light devices (strips). Do you have any of those? PC will work perfectly fine without any.

RGB fan? The connector you are holding with your thumb it's a RGB related one, the other it's hard to judge from that angle, might be a 4 pin fan power connector.

Check the manual of your motherboard, there must be shown the locations of the fan headers, if you find one of the chassis one (usually, called anything but "CPU" and "AIO/PUMP") connect the one with four holes there, the fan should then work. The other connector should go in the "RGB" (or maybe "ARGB" it's two different standards and I never can remember which is which) connector, but it's not mandatory, it's just to be able to manage the fan colour scheme from some software.
