Currently I'm testing the 360 on the test bench.. It's connected to the psu (molex), and I have three lian li uni fan sl120 linked together with a single cable (w/jst to argb connector) going to the 360, plugged into Rgbpx #1 (standard argb connection)..
Describe the complete cabling, ALL cables are important. Without a COMPLETE description/pictures, no one can really help you.
