I just got a new 120mm (second fan on the rig) which I just installed. As soon as the computer turns ons it turns off after 3 seconds. Then When I unplugged the fan it was fine, then I plugged the fan and unplugged the LED and it was fine. I'm assuming I don't have enough power to run them all.. Any suggestions besides buying a new PSU? I have the new 120mm hooked up to the "NB Fan" Slot, what's NB? the "SYS Fan" has 4 pins unlike the connector which is 3... I'm confused on that part, help please, Thanks
