i have 6 HD120 RGB fans on mine, and they work GREAT !!!
matter of fact !
ALL 12 of my fans are Corsair HD120 !!:sunglasse
only downfall for this ole boy is when i play farcry 5 my Rad & CPU lights dont light up !
already chatted with Corsair about it bout reckon i will have to wait & see if they make a firmware update !
