I recently went nuts doing a near all TT build in regards to case, fans, PSU and CPU Cooling. It has been a rough couple of days getting this stuff to work. The best I had it was last night where I had everything being seen by the software and running as I liked with the eception of the two front Riing Trio 20 fans having three led's not winning to change colour like they are burnt in. I have stopped using the TT RGB Plus software for now and letting them cycle in the rainbow default and these couple of led's on each DO NOT CYCLE COLOURS STILL. When I booted up today the second fan controller is no longer being seen by the software nor os the PSU. I already downsized from three controllers after the third stopped being seen after one day now I am going through it alll over again. The software needs a complete overhaul. It is ugly and really doesnt work well. If I cant get this stuff working I'll be looking for a refund on EVERYTHING from Thermaltake directly as these are not working as they should. The PSU is connected directly to the motherboard as for some reason i it doesn't have a plug compatible to the fan controllers? How many USB 2.0 heads on the motherboard do you guys want to waste? I had to sacrifice not having USB 2.0 on my front case panel this is stupid.
