V+12 voltage in enclosure Internal is out of spec. (10.72 V).
I am getting since yesterday this error message, repeatedly: V+12 voltage in enclosure Internal is out of spec. (10.72 V). Nothing changed, no recent update, I am running 6.6.1 since near 4 mont...

Unfortunately, that's most likely impossible to tell for sure. If the voltage is out of spec, then it's a problem, even if it appears to be working. If it's not out spec, then it should work without issue.
Now, what's out of spec? Good question. If you really want to explore in that direction, I would first try to measure the actual voltage as Sandshark suggested. If you consider PSU tolerance, then 11.4V seems to be the minimum 'in spec': https://www.lifewire.com/power-supply-voltage-tolerances-2624583
Though I do not know for sure what is the minimum voltage on the 12V that the different components would "accept", I personnaly wouldn't feel comfortable if it's not within the standard PSU tolerance. Then the components are not designed to work it, and you may encounter random issues. Not exactly what you want with your data storage.

The new brick did not fix my issue
I get low voltages as of 10.40V !
Have I to worry about it, sensor issue ? Power issue somewhere else ?
I'd really appreciate some help

Unfortunately, that's not an easy thing to do. The voltages are accessible on the rear of the SATA backplane if you want to disassemble it and check with a volt meter.
If it keeps working fine, it's probably just a sensor issue.

For now, I see no issues on the NAS at all, no hangs, no fails
