Tip: Before moving to the lengthy solutions, try reinstalling the fan or lighting hub and checking for loose or faulty cables.

Change The Fan Type

When using the iCUE software to customize the lightning in Corsair fans, there are multiple types of fan types, and you have to select the type you are using on your PC. By default, the software is designed to autodetect your fan type. You only have to plug in your fans, and they get automatically lit up.

But sometimes, this glitch in the software requires you to select the right fan type yourself. This technique helped solve the issue for many users on the Corsair community platform. Follow the steps below to do it:

  1. Launch iCUE Software: Open the iCUE software > Click the pump from the top of the Window > Go to “Lightning Setup.” > Click “Run Wizard” > “Next” > “Next” again.

Check The Power Supply

The issue can also be caused due to an insufficient power supply. Therefore, it is recommended that the power supply cables be checked to ensure they provide enough power to the fan. Additionally, check for any signs of wear or damage to the cables and replace them if necessary. Many users on the Windows 10 forums also claimed that a faulty PSU was why their RGB fans couldn’t light up.

WARNING: A low-quality power supply or cables can cause the voltage to drop, leading to the failure of the fan to light up. It is important to use a high-quality power supply designed for gaming or high-performance computers.

Last Words

These were all the valid solutions you needed to know to fix your Corsair fans not lighting up. As this issue lies with the iCUE software most of the time, it’s important to check for and install updates for your Corsair fan to ensure it’s running with the latest features and fixes.

One more potential cause to consider when troubleshooting the issue is conflicts with other software or hardware installed on the computer. This can occur when two or more programs or devices simultaneously try to use the same resources, such as the USB ports or the graphics card.
