Yes I understood this with the ports first hand:) The thing is that I m way below the limit since asus supports 500 leds and I m at 48 with the 4fans*12 leds each, also how do you count leds since are all plugged in the tt controller? I mean the one of the two ports on the mb is used and it goes straight to the controller, so if I put in aura settings 12 leds then the one fan in the 4th port connected is shutting off its leds, from that point either I put 24, or 36 or 48 results are the same, mentioned earlier. Something fails to multiply the same signal to all ports, is it the controller that receives one and only signal frim the m/b or the m/b that sends faulty bitstream?
