CPU fan no longer seen (at zero RPM)

This is with Aida64 Extreme v6.80 on Windows 10 x64 with an MSI x570 mobo.  I use "FanControl" by Mercier (excellent!) for all of the many fans in my PC.  So many that I don't need the paired Noctua NH-U12A CPU cooler fans to be running under most desktop conditions.  But at zero RPM, Aida64 no longer senses their presence.  So the System Stability Test graph doesn't show them or even offer them in its Preferences list.  If I do get them to appear, they disappear eg. from the graph when their speed drops to zero RPM.

[LATER  This happens with several chassis fans too.]

Yes, I'm afraid that's how it works with AIDA64 since an unconnected motherboard fan header and a fan header with a connected but not currently spinning fan appears similarly to software.  So when AIDA64 cannot sense a meaningful RPM readout for a fan header, it will assume there's no fan connected to that fan header.
