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

The nb plug cold possibly be for Nort Bridge fan which are usaly small so i would say that there is the problem trying to run a second 120mm fan from the motherboard.... so sa g-paw said use the molex connector from the psu and it should be fine.

is can receive 3 pins

, it also came with a lil extension with the same end but a little thing on the wire, probably as a circuit breaker.

got it to work, eventhough the connector was 3 pins it was the mobo is designed to fit both 3 and 4. I got it working. You guys we're right, that was the North Bridge fan plug. thanks
