I have the latest Aida64. 6.33.5700. I'm using an ASrock extreme wifi 6E mobo. The 2 fans I normally use show up okay in Aida64. So I don't have a problem, but I noticed when I plugged in a fan in another header to check the speed, it didn't show up in Aida 64, but it did show up in the BIOS.
It's the CHA_FAN4 that is missing.
