If you have a Corsair iCUE Elite CPU Cooler with LCD display and are getting error messages on the LCD it may not be immediately obvious what those errors mean. We’ve provided this resource page to help you decipher the error code meanings.
You should see one of two icons when there is an error:
Pump Error – Pump Not Working Properly
General Fault Error – Issue Not Related To Pump
Pump Error
This Pump Error shows a red square with circular edges and a broken sinning impeller missing a single blade. There is an exclamation mark in the bottom right corner indicating an error.
Meaning: This error code indicates that your pump is not working properly. You should immediately turn the system off and run troubleshooting procedures or you risk burning out a component due to overheating. Corsair recommends following these diagnostic procedures to see if you can fix the error:
==================
- Push down on the 20-pin that goes from the LCD module to the Commander CORE to make sure it is fully seated; the white stripe on the plug should align with the white stripe on the Commander CORE housing.
- You also want to check the 20-pin to see if any of the pins are damaged.
- Give the LCD cap a light push to make sure it is in full contact with the 8-pin.
- NOTE: Make sure that you only do this when the cooler is powered off, since the pump loop is sensitive to voltage inrush and can be damaged if you push the cap when the power is on.
Please note that if you plug in the LCD while your PC is on, you may have damaged the pump’s tachometer sensor, which will lead to the error. In this case, contact Customer Support and we will provide further assistance.
==================
General Fault Error
The general fault error will show up as an exclamation point inside of a triangle. This error code means that something is wrong with your AIO cooler but the pump is working normally (this error covers all types of errors that are not related to the pump). Most of the time this error has to do with information not properly being sent to the LCD and/or possible issues with firmware updates that are needed, etc. (especially if you bought the LCD as part of an upgrade kit).
Corsair recommends the following troubleshooting steps be taken first:
Try the following to see if any of the steps solves the issue:
==================
- Push down on the 20-pin that goes from the LCD module to the Commander CORE to make sure it is fully seated; the white stripe on the plug should align with the white stripe on the Commander CORE housing.
- You also want to check the 20-pin to see if any of the pins are damaged.
- Give the LCD cap a light push to make sure it is in full contact with the 8-pin.
- NOTE: Make sure that you only do this when the cooler is powered off, since the pump loop is sensitive to voltage inrush and can be damaged if you push the cap when the power is on.
- If you have another PC, connect the Commander CORE to that PC and use iCUE to force update the Commander CORE firmware to the latest version.
- If you have checked the connections and are on the latest firmware, try a full power cycle by unplugging your PSU from the outlet, press the power button several times to ensure the power is fully discharged, then plug your system back in and reboot.
- As a last resort, do a full uninstallation of iCUE to remove registry keys and all files from your %APPDATA% folder, then perform a clean installation of iCUE.
- NOTE: You can save your current iCUE profiles by exporting the profiles onto your computer and then importing them again once you perform a clean reinstallation of iCUE.
