  1. Hi again After long testing session and altering all available settings in BIOS I came to conclusion that I have to use extra power directly from PSU, like the author of this topic suggested. I am pretty sure that in my case (MOBO Gigabyte GA-Z170-Gaming-K3-rev-10) more power is avaliable from CPU fan headers than from SYS fan headers. When I connect fan hub (with up to four fans) to CPU_OPT it will always start correctly, LED flashes and stays on - always. However when I connect the same hub to SYS header its more like 50/50 chance that the LED will stay on. And here's the fun part - it doesn't matter if I connect four or just two fans to the controller. It seems SYS header does not offer enough power on my MOBO (which is weird because this is quite expensive and new MOBO). Changing PWM setting in BIOS to max does not help with anything. BTW, can anyone explain how to extract 12v & GRD from SATA cable? Yellow is 12v and black is GRD?
  2. Turns out it was too low RPM setting. After I installed Gigabyte Information Viewer and manually assigned slightly higher RPMs the flashing stopped. Fans are still very silent. Now when I turn on the computer the fans flash (only when set to white) and after Windows starts and Gigabyte App Center starts the flashing stops. I am guessing that if I turn up RPMs a little in BIOS it will also work.
  3. Thanks for help. Will try it out later and post results.
  4. Just to be clear, I do not need to use separate power feed when using 4 fans with one controller? My MOBO is Gigabyte GA-Z170-Gaming-K3-rev-10, I connected the controller to SysFan module. I am using Chieftec CFT-750-CS as PSU. Since I have another controller I will test it later and let you know.
  5. Hello I used this instruction to connect 4 RGB fans to one hub but there is one problem - all colours except from white work correctly but white colour flashes. Because of this the 256 mode also flashes and restarts. I was thinking (this is really a wild guess) that the reason for this could be power shortage (white uses the most power because all lights are used to mix all three colours?). I also noticed that the two fans which share the connector rotate slower than the other two fans. Does anyone has this problem as well? Any idea what might be the cause?
