So i wanted to connect the case rgb cable
Because its capable of aura sync
And my motherboard has a 4 pins
But the case has only 3 holes in it for 3 pins only
Sorry for my English

Keep in mind, the 3-pin RGB header is the 5V addressable one, and the 4-pin header is the 12V RGB one, they are not compatible each other.
You can buy other MB like X470, because they will have either the 3-pin and 4-pin RGB header. Or buy an addressable RGB controller.
