ICUE SOFTWARE
You can download the latest version of the iCUE software from the download section.
Once launched the software detects and lists all compatible CORSAIR devices.
Clicking on the K70 RGB MK.2 reveals the current RGB lighting effect and all the available zones (104 keys plus the CORSAIR logo and the extra media and command buttons).
The iCUE software allows you to program all of the keys by assigning commands, macros, texts, timers, shortcuts and much more onto them from the actions tab (check the above screenshot for more details).
From the lighting effects tab not only can you choose one of the 9 available effects (or even create your very own) but you can also adjust their speed, direction and combine as many of them as you want with the per-key lighting feature (as seen above).
Inside the performance tab you can only adjust everything related to the Windows lock key.
CORSAIR allows the end user to monitor the status of the system from the dashboard menu as seen above.
If RGB lighting is not your thing you can choose instant colors for the keyboard from this drop down menu.
The polling rate along with the brightness levels, firmware updates and more can be accessed from the settings menu.
Here you can see the lowest and brightness levels of the keyboards (two top pictures) along with some of the effects and single colors available (the last picture is of the custom one we created).
