Getting a lot of these types of errors since the update to 13.0 U6.8:
WARNING
I took these as warnings until a loud beep was constant last night around 2am - turning off the NAS of course remedied the noise, but when I was upgrading disks I noticed the same warnings but never saw the CPU fan spin.
I suspect it could just be the CPU fan and thermal grease issue (dried out). I see many people complaining online about this similarly though.
What make you think it is related to 13.0 U6.8 and not a failing fan or cooling? If the CPU fan connector spins other fans, the CPU cooler fan failed or is failing.
Been seeing same errors for many but on different versions (some goes back to 2022).
Maybe I have it backwards like most: if getting those errors, it is the cpu fan (or cpu fan port) that failed if cpu fan is not spinning. It’s not about the TrueNAS version, just that people note when it first happens what TrueNAS version they are on.
Anyway, ordering a new CPU cooler (1151) for my NAS running intel i5-9600K processor.
