I want to buy a single rgb fan to even out the lighting in my pc, but when I check the one I am interested in, the Corsair LL120 fan, it says that it needs a controller to function. Is this true, or can I simply connect it to my motherboard (GIGABYTE X470 Ultra Gaming) and be able to control it with no problem? And if I will need to buy the controller, would I need to buy " a RGB lighting hub and lighting Node Pro" as it says, or can I just buy the Lighting Node Pro?
