Current fan setup:

2 Noctua NF-P12 (Radiator)
2 Fractal Design Case fans (hooked up to 3 pin fan controller)
2 Noctua NF-A14 Case fans each plugged into motherboard 4 pin connector

750W power supply (I need 500, enough wattage to go with..)

The problem is.. 1 Noctua NF-A14 which I recently added is not spinning, it's rather twitching. Like it's willing to spin every 2 seconds but it does not get that power to do so.

I've tried hooking them up to different 4 pin connectors but neither of that seems to work. I'm left with 1 Noctua NF-A14 spinning just fine, whilst the other is twitching. The fan it self is not defect.

Is this a motherboard problem?
