Hi I have ordered the parts for my PC and it’s on the way. I bought the Corsair 500d Mid-Tower, H115i RGB cooler, 8x2 Vengeance RGB 3200, HX850i, LL120mm Fan and the Nop kit. I just wonder do I need to buy the Corsair Fan Hub 6Port for my building or not? I don know if it comes with the case or the cooler or neither. Does the LL120mm can connect to iCue itself like other products? Thank you.
