SignalRGB currently cannot control the screens on NZXT’s Kraken Z line of coolers.
The current workaround to get rid of NZXT CAM is to use KrakenZPlayground.
KrakenZPlayground allows you to replace NZXT CAM and still retain the ability to control the screen on your Kraken Z series cooler.
Download the latest version of KrakenZPlayground from this website.
Extract the entire app into a new folder.
Open the KrakenZPlayground.exe file and enjoy!
