ASUS Crosshair X670E Hero - CPU OPT fan display on sensor panel stops working

[djf720]

On the sensor panel, the fan reading "CPU OPT" works fine on application start-up after reboot. After about 2-3 minutes the fan reading reverts to 0 RPM and stays there. If I install Armory Crate, it shows the fan speed OK. Restarting the application does not fix the issue. Updating the BIOS and ASUS drivers does not fix the issue. This has been occurring with successive AIDA updates.

Computer details attached.

Try to enable Embedded Controller (EC) bank switching in AIDA64 / main menu / File / Preferences / Stability.  Let me know if it helps.
