The NZXT came today and the Aero Cool 120mm fan LED's do not flicker in case anyone is interested.
So far I think this FC is not bad for my what I wanted it for I like it so far.
No flickering from my fan LED's, no buzz or hum sound. One other thing you can only use fans that draw up to 10w max with this fan controller. Touch screen works good no problem and the light on the display is not too dim or too bright. Very easy to hook up and operate
