Corsair RGB Fans not working

If you’re having trouble getting iCUE to detect your Corsair RGB fans, here are a few things you can try to fix the issue.

1. Check hardware compatibility

First, check the minimum system requirements for ICUE on the Corsair website. If your system meets or exceeds those requirements, you should be able to use ICUE without any issues. If your system does not meet the minimum requirements, you may need to upgrade your hardware to use ICUE.

Second, check to see any updates available for your motherboard or CPU. If there are, install those updates and then try using ICUE again. Sometimes, new updates can enable compatibility with ICUE that wasn’t there before.
