[SOLVED] Are 4 Pin motherboard RGB wires a thing?

[jessicat1261]

So I've been looking at things like this: https://m.aliexpress.com/item/10050...gaeuhhecacij1789ce5271122dba06ce24c213&gclid= and I noticed none was 4 pin,the problem is I have a 4 pin so I wondered if that was even a thing?

RGB is 4-pin, aRGB(addressable RGB) is 3-pin.
aRGB uses the same style header but is missing the 3rd out of the 4 pins.
and you must match type of cable with proper header or it will cause damage to the device.
