The software you use should match the model of Wraith cooler you have.The cooler can ONLY be connected to a standard USB 2.0 header. FYI, I'm guessing the AMD USB HEADER on your motherboard is proprietary and is not compatible with this cooler.In this state, the software will not be able to communicate with the cooler.

If the RGB wire is connected, the controller will default to using the RGB control and USB control will be turned off. For color control, however, ONLY the USB wire should be connected to a USB 2.0 header. Of course, for fan control, the fan header should always be connected to the CPU fan control header on the motherboard.The Razer Synapse 3 software can be separately downloaded from this link.There are two conditions that must be met in order for the Wraith software to work:

Once installed, you'll need to select 'Enable Chroma Connect' in order to hop on the Razer Chrome bandwagon. To get started, you will first need to download the Ryzen Wraith Prism RGB lighting control software (you can grab it here). Users will be able to choose from 16.8 million colors and customize effects across accessories with games or automatically based on your own personal preferences. Some of the big names in the business that support Chroma include MSI, Zotac, G.Skill, Lian Li, Biostar, Colorful, ASRock, Antec and a host of other players. As a result, the cooler is completely compatible with Razer Synapse 3 software so that you can sync your Ryzen's cooler with the other Razer peripherals and any other device/hardware that is Chroma-compatible. Razer is now tapping into the lighting scheme by announcing that the Wraith Prism now has full support with its Chroma Connect initiative. All of AMD's Ryzen 7 and Ryzen 9 processors come with a Wraith Prism cooler in the retail box, which of course supports RGB LED lighting.

AMD's third-generation Ryzen processors are finally here, and they deliver on nearly all of the promises made during the company's Computex 2019 announcement.
