Solved Pre installed cables in NZXT Phantom 820 Tags: NZXT Systems Cable Last response: November 30, 2013 3:54 AM in Systems Share Cowboysjj July 12, 2013 4:07:54 PM What are all the 3 pin cables that come installed in the case that have stickers on them labelled: F, IS, R, and T. Do I need them? What are they for? What do they connect to? More about : pre installed cables nzxt phantom 820 Reply to Cowboysjj Best solution Conor4011 July 12, 2013 5:50:21 PM Sounds like 3-pin fan cables to attach to optional case fans that you could buy. Front, ?, Rear, and Top. They connect to the fan controller on the outside of the case and to optional fans inside the case so they can be controlled.
