In normal usage, the LCD display located on the CPU block shows the current temperature of the coolant liquid, the speed of the fan, and the pump speed, as you can see in Figure 9. It also shows the current operating mode: Quiet, Performance, or Extreme.
When we tested the cooler, we set it to "quiet" mode for the idle test, and then in "extreme" mode for the full CPU test, but the system kept the fan and the pump at the same speed in both tests.
Using the buttons located on the CPU block, you can navigate through the product menus. There are two menus: Display and Settings. On the display menu, shown in Figures 10 and 11, you can change the color of the LCD backlight, set this backlight to blink slowly, and turn the LCD data orientation to mach the position you have actually mounted it. The LCD backlight can be set to one of the six available colors, turned off, or you can set it to change the color according to the temperature of the liquid.
On the Setting menu, you can set the display to show the temperature in Celsius or Fahrenheit, set the operating mode (Quiet, Performance or Extreme), and re-load the factory defaults.
