Report [GUIDE] How to connect up to 6 Riing RGB fans in 1 controller in Case Fan Posted August 7, 2017 3 minutes ago, Qlemens said: Just to be clear, I do not need to use separate power feed when using 4 fans with one controller? My MOBO is Gigabyte GA-Z170-Gaming-K3-rev-10, I connected the controller to SysFan module. I am using Chieftec CFT-750-CS as PSU. Since I have another controller I will test it later and let you know. It is more like case by case situation with 4 fans and sep. feed. Also check your bios. I know gigabyte defaults fans to 0.5 rpm. It might affect.
