Corsair Crystal Series 680X RGB Case Review


Since the included Lighting Node PRO and LL120 fans are iCUE compatible you can control them using Corsair’s iCUE software. The latest version of the iCUE software can be downloaded from Corsair’s website. For this review, we will focus on the elements of the software that pertain to the Lighting Node PRO and LL120 fans.

Once you install and run the software, it will automatically detect all your iCUE compatible devices. As you can see, the pre-installed Lighting Node PRO was found. If for some reason you don’t see your device, just shut down and restart the application. We have had this happen in another Corsair review, and a simple restart of the software resolved the problem.

After selecting the Lighting Node PRO from the device list, you get an additional navigation bar on the right to configure the device as well as the lighting for any attached fans. In the left pane, you will notice a photo of the Lighting Node PRO as well as its current configuration below the image. For our 680X, the three LL120 fans are installed on port one so we go ahead and adjust the configuration to reflect this.

Now that the Light Node PRO has been configured, we can adjust the lighting effect for port 1 using the left navigation pane.

The iCUE comes with a lot of predefined lighting effects that you can additionally configure settings for, such as speed, color, and direction.

Predefined/Lighting Link:

  • Spiral Rainbow – Cycling through all the colors of the rainbow in a circular motion
  • Rainbow Wave – Cycling through all the colors of the rainbow going left to right
  • Visor – Random/alternating colors moving across the LEDs then bouncing off the last one and returning to the start
  • Color Shift –  Shifting between random/alternating colors
  • Color Pulse – Fading random/alternating colors in and out
  • Color Wave – Like visor except it doesn’t bounce when hitting the end of the LEDs
  • Temperature – Have your key change color based on various temperature sensors
  • Sequential – Coloring each LED one by one and then starting over with a different color when reaching the end
  • Marquee – Flashing somewhat like a marquee sign
  • Rainbow – Fading colors through the color spectrum
  • Strobing – Blinking LEDs on/off and changing the color each time
  • Rain – Rain-like effect across all LEDs with random/alternating colors
  • Arc – LEDs circling in each and changing colors each time it completes the circle
  • Heartbeat – Random colors fading in and out resembling a heartbeat
  • Color Warp – Changing colors up and down the color spectrum


  • Static Color – Solid static color that is always on
  • Solid – Solid color that can have the occupancy and lighting time configured
  • Gradient – Gradient of 2 colors that can have the occupancy and lighting time configured
  • Ripple – A ripple effect with a configured color, occupancy, and lighting time
  • Wave – A wave effect with a configured color, occupancy, and lighting time

Once you have selected your desired lighting effect, you can see how it will look in the upper right pane. If you which to change attributes such as the speed, direction, and colors you can do this on the lower portion of the screen.
