In the next section, you will find the list of error icons you may see on your iCUE ELITE CPU cooler LCD screen, their meanings, and potential ways to fix the issues.
iCUE ELITE CPU Cooler LCD Error Icons
The LCD screen attached to your iCUE ELITE CPU cooler usually shows two error icons: a square icon with a spinning impeller and a triangle with an exclamation mark.
Error Icon #1: A Square Icon with a Spinning Impeller
If your iCUE ELITE CPU cooler LCD screen shows a red square with a spinning impeller inside (see the image below), it means there is something wrong with the pump. The Commander CORE is not receiving any tachometer signal from the pump. In other words, there is a communication problem between the Commander CORE system and the pump’s tachometer.
- Commander CORE: It’s a control unit inside your CPU cooler responsible for monitoring and controlling the operations related to system cooling, such as pump speed.
- Tachometer: It measures the rotation speed of the pump. The tachometer is integrated into the pump of your CPU cooler and provides crucial information related to the pump speed.
The tachometer reading is transferred via a digital signal to the Commander CORE. The signal is used by Commander CORE to ensure that the pump is functioning correctly.
If the signal does not reach Commander CORE, you are likely to see an error icon with a rotating impeller.
What could be causing the problem: If you are seeing this error icon on your iCUE ELITE CPU cooler LCD screen, there is a chance that the pump’s tachometer sensor is damaged. It can happen if you plug in the LCD when your PC is turned on.
The error icon might also appear if the pins connecting the LCD module to the Commander CORE are not fully seated. You would also want to ensure the LCD cap is in full contact with the 8-pin. Lastly, you might want to check if any of the pins are damaged.
There are a couple of solutions you can try to resolve the communication problem. If any of them works, great! However, if the problem persists, you may need to reach out to customer support.
Solutions to this problem:
Solution #1: Check the Pins
First things first, you would want to make sure the 20 pins connecting the LCD module to the Commander CORE are not damaged. Carefully observe the pins. Even a single damaged pin can cause issues with communication between the LCD screen and the Commander CORE.
If the pins are damaged, you will need to replace this part. However, if there is no damage, blow some air toward the pins to remove any dust and then check if the error icon is gone. If the problem persists, you would want to try other solutions.
Solution #2: Make Sure the Pins Are Fully Seated
If you are seeing the error icon – a spinning impeller inside a square – on your LCD module, make sure all 20 pins that go from the LCD module to the Commander CORE are properly seated. The white stripe on the plug should align with the white stripe on the Commander CORE housing.
Solution #3: Push the LCD Cap a Little
You might see the error icon if the LCD cap is not in full contact with the 8-pin. To ensure it’s not causing the error, give the LCD cap a slight push. Please do not perform this when the cooler is powered on. It can damage the device. You should therefore turn off your iCUE ELITE CPU cooler before pushing the LCD cap.
If none of the above solutions worked out in your favor, there might be a problem with the hardware which needs to be checked by a professional. You should reach out to Corsair customer support to get it repaired.
Error Icon #2: A Square Icon With an Exclamation Mark
Another error icon that you may see on your iCUE ELITE CPU cooler LED module is a square icon with an exclamation mark. It means there’s some problem, but that’s not related to the pump. The error icon means general fault error, which, according to Corsair, typically occurs when the LCD module does not receive any data from the Commander CORE.
Fortunately, there are a few ways to rectify this error. Check out the solutions below and test them one by one until you find the one that works for you.
Solutions to this problem:
Solution #1: Update your Commander CORE’s Firmware
The issue has been majorly reported by users who bought the iCUE ELITE Cooler LCD Display upgrade kit. Probably, the Commander CORE has not been updated to the firmware version that supports the LED module.
You should therefore update the firmware to fix the issue. For this, connect the Commander CORE to the PC and use iCUE to install the latest firmware for your Commander CORE.
If updating the firmware does not work, try other solutions mentioned below.
Solution #2: Check if the Pins Are Not Properly Connected
If you are still seeing the exclamation mark error icon on the LCD module, probably the pins are not fully seated. Make sure all 20-pins that go from the LCD module to the Commander CORE are properly seated. The white stripe on the plug should align with the white stripe on the Commander CORE housing.
Solution #3: Check if the LCD Cap Connection Is Loose
If the LCD cap is not making full contact with the 8-pin, you may encounter an error icon. To verify if this is the cause of the error, gently push the LCD cap. However, it’s important to note that this should not be done while the cooler is powered on, as it can potentially damage the device. Hence, prior to pushing the LCD cap, make sure to turn off your iCUE ELITE CPU cooler.
Solution #4: Power Cycle Your CPU Cooler
If the above solutions did not work out in your favor, try power cycling your CPU cooler. It will reset the system which could fix the error. Unplug your PST from the outlet. Now, press the power button a few times to ensure that no residual power is left in the device. Finally, plug your system back in and reboot the device.
After power cycling your CPU cooler, check if the LCD module still has the error icon
Solution #5: Uninstall iCUE
Before reaching out to customer support, the last thing you can try is uninstalling iCUE. It will remove registry keys. After uninstalling iCUE, remove all files within the %APPDATA% folder. After this, perform a clean installation of iCUE.
The LCD module connected to your iCUE ELITE CPU cooler should not repeat the error. However, if the problem persists, it could be a hardware fault that needs to be checked by a technician.
