I devised a few theories and this is the best config I created if you have 4 fans.
I have 2 front let's call them A and B. 2 top let's call them C D.
1. Controller
1 position - leave empty
2 position - A
3 position - C
2. Controller
1 position - leave empty
2 position - B
3 position - D
WHEN SETTING RGB THERE IS A SMALL DELAY BUT IT LOOKS GOOD. In this setup there is a cool pulsating look to this kind of delay.\
(To fix hibernation see my hibernation fix in this forum)
TO COMPLETELY SYNC RGB GO INTO HIBERNATE, CUT POWER, RESUME.
This works by exploting multiple bugs at once.
You only need to set speeds in the 1. controller. Due to a bug it will set top and front both fans at the same time.
At this point I dont care for any updates. I've debugged, reverse engineered and #### with this thing for 3 days and I finally have everything working.
The fans hardware is good and they look great. But I defenitely do not recommend them to anyone, even if you have both the hardware and software rev eng skills. Not worth the risk/reward for the effort you have to put in and get lucky figuring out how some part of this broken thing works.
