you were right cuecue, you indeed dont have to plug anything into the back of the fan molex conector for it to work. I dont know why, but the past 2 times ive tried it, it didnt work. apparently i was doing somehting wrong, cause its working this time around. but damn, removing all those sata to molex adapters and gpu 6 pin to molex connectors, along with wiser cable management, cleared up so much clutter in my case. thx for the input guys.
