NZXT KRAKEN ELITE 240 RGB Fans and Screen not functioning

my kraken elite 240 turns on and pumps liquid through the radiator but the fan it came with and the screen don't turn on? nzxt sent me a new one to test, i've swapped motherboards and cpus but the screen+fans will still not function, no matter what usb slots i plug it into. does anyone have experience with a similar problem? thank you in advance
