This is the PredatorSense app on the 21 X. The first is the Monitoring function, where we can see the CPU and GPU temperatures. The next, a Hotkey function, where we can select up to fifteen powerful hotkeys. You can even record and customize your own macros. The Lighting section allows you to fully customize your full-sized mechanical keyboard with all kinds of RGB colors and patterns. The cooling section allows you to fine-tune your fan controls. You can select custom and individually tune every fan to your liking, and you can even turn on CoolBoost™ for higher RPMs. Once you’ve maximized the fans performance, you can overclock both the CPU and the GPUs in this powerful 21 X machine.
