How are connected the RGB Fans

[mad_ragnarok]

Hello, I want to buy the MasterBox MB500 case from Cooler Master : http://www.coolermaster.com/case/mid-tower/masterbox-mb500/

the only question I have is how the fans are connected? (Power and RGB).
My motherboard is a Gigabyte B450M DS3H: https://www.gigabyte.com/Motherboard/B450M-DS3H-rev-10#kf
And it has a 4 pin connector named: LED_CPU. I don't know if that's the pin I can use to power the RGB fans.

btw: The model that I can buy is the one without the RGB Splitter
