The 12V and 5V RGB sync cables of the hub cannot be connected to the main board together. You can only choose one of the two
1. The hub is connected to the motherboard's 5V RGB interface via a 5V sync line
-Fan connected to the 5V interface of the hub, the light is normal and the mainboard can be synchronized, the mainboard controls the dimming, and the speed is normal.
-The fan connected to the 12V interface of the hub, the light is not bright, cannot be controlled, and the speed is normal.
2. The hub is connected to the 12V RGB interface of the motherboard through a 12V sync line
-For the fan connected to the 5V interface of the hub, the light cannot achieve the magical light effect, but the mainboard can be synchronized, and the mainboard can control the dimming, only monochrome, and the speed is normal.
-The fan connected to the 12V interface of the hub, the light is normal, the dimming is normal, the main board can be synchronized, and the speed is normal.
3. The hub is not connected to the light line, and the speed control line is directly connected to the 4Pin interface of the motherboard
-The fan connected to the 5V interface of the hub, why the lighting achieves the illusion equivalent, but the motherboard cannot be synchronized, relying on the 5V program that comes with the hub to automatically cycle and dim, and the speed is normal.
-The fan connected to the 12V interface of the hub has no light, and the speed is normal.
