How can I connect a 4 pin rgb (12v r g b) to a 3 pin sys fan header?

Ok so basically I just got this case with built in rgb fans but the only connectors it has is the 4 pin rgb thing. But, my motherboard (gigabyte z370m ds3h) only has a sys fan connector afaik (please correct me if I'm wrong) and I really don't want my computer to melt so does anyone have a method of connecting them?

4 pin fans will work in 3 pin connector. The down side is that they will not be speed controlled and run at 100%.

If you want to be able to control the speed, buy a "PWM fan Hub".

Your motherboard doesn't have any RGB connectors so you will need to buy a separate RGB controller.
