I just got this case yesterday and my only problem with it is the fans. I've tried disconnecting the SATA which makes the fans run at low speeds when they're rated at 850 ±250 rpm in the manual. The highest speed they get to is 683 rpm. The 12v blue connector is plugged in for my lightning. What can I do to fix this?
