hi, im going to be honest, im young and dont know alot but i do know from research into watercooling, if you bridge two pins in the main 24-pin power wire then the fans and leds will start but not the main system for you to be able to start the watercooling loop without the system booting up. (What im gettig at) there may be a problem with your 24 pin connector, this could be swapped out easoly for only £8 (the price if the cable) i dont know if that is the problem though, sorry.
