Sorry to bother again. Ty for your advice. I ordered 3 of the SP fans to match the 3 included. I have run into a new problem though. Testing the 3 fans up front with the Light hub in the back, which every fan is plugged into slot 1 the RGB works. Fans plugged into 2, 3, 4, ,5 ,6 RGB do NOT work. Is this a defective case?
