I see this a lot on fan hubs such as rose wills where a 3 pin connector goes to hub and the end goes on a m/b addressable header on the motherboard I’m assuming. Problem is my motherboard only has two rgb headers and both of them are 4 pin or circles (gigabyte x370 gaming 3) and the connector that is labeled for gigabyte motherboards looks like a 3 pin , but uses pins instead of the circles like in my wraith rgb cooler am I supposed to put this connector on one of the sys fans headers?
