Razer is about to make it considerably easier to control your RGB-lit gaming rig. The company has unveiled plans to introduce Amazon Alexa control through its Synapse 3 software, letting you voice control devices that support its Chroma Connected Devices Program through Razer headsets and microphones. That includes legions of Razer's own mice, keyboards and audio devices, but it also includes PC cases, cooling fans, motherboards and other peripherals. Want to turn your setup blood red for a round of Doom? You'd just have to ask Alexa to change your lighting profile.
