Here's the thing though, if you've plugged in BOTH the 4-pin connector and the USB connector from the Wraith Prism to your motherboard, the Coolermaster Wraith Prism Utility will not take control. But you will lose that SYNC functionality with RGB fusion. When the Wraith Prism is connected to your motherboard using the USB header, the Coolermaster Wraith Prism Utility will have full control over all zones on the Wraith Prism including chase effects etc. When the 4 pin connector on the Wraith Prism is connected to your RGB header on the motherboard, RGB Fusion will control and sync the Wraith Prism Fan LED, but NOT the outer ring LED or the AMD logo LED (these will always remain at default which is rainbow for the ring led and white for the AMD logo) I also had these issues and this is what I've found from my testing. I recently bought the 2700X and Gigabyte X470 Ultra Gaming.

Since your post is so vague without any computer information as per AMD Forum: INFORMATION REQUIRED WHEN POSTING A QUESTION.
