This would also be the reason why some places would not list it as compatible with Gigabyte, due too them using two different headers over the years. There maybe adaptor cables still around you can get to make it work tho. Only thing to look out for is that older gigabyte motherboards (Z370 or lower) ran a different 3 pin header call VDG, if you have a older motherboard then this may be a issue. I have even done a PC with over 500 LED lights with a gigabyte motherboard using its 2 ARGB headers. I have used, thermaltake, silverstone, coolermaster, deepcool, msi, coolmoon, fans all with gigabyte motherboards and have had no issues, except the software its self. Something like this - A-RGB 1-to-3 Splitter Cable | Cooler Master If not it will come with or you will have to buy a ARGB 3pin 3 way splitter cable. Then you should be able to control the lighting with RGB Fusion. on the control box you press a button to set it too motherboard signal. Then there will be a 3pin ARGB connector that goes from the control box to the motherboard header. Im pretty sure the CoolerMaster Sickleflow 120 ARGB fans hook up to a small controller you get in the 3 pack box. will work with any ARGB with 3pin ARGB connector. They will work with Gigabyte argb motherboard header.
