@Samuel Tai, thanks for your prompt attention to this matter.
Please note that I was the second user this month posting about this issue. This forum is invaluable to the TRUENAS community. My comment was to add value to the original March 2021 post in that the suggested solution does not solve the issue in all cases.
Will happily start a new thread after I get a chance look at a few items. Searching and reading a few other (mostly older) posts did not turn up an obvious answer. For clarification, my system(s) are set to use English and I did not look at any elements (other than cpu and disk) in the Reporting tab in my Test system.
But my comment was made to correct an error, in that the suggested settings from 03/2021 DO NOT fix the problem in all cases.
I understand that SATA is not SAS. My other X10SL7-F system is using SATA drives on the SAS controller and the temps are being reported. Again, I did not look at any other values on my Production system in the Reporting tab (was not in 'testing mode').
Supermicro specifies the X10SL7-F controller as a "SAS2 (6Gbps) via LSI 2308". A link to some info on the 2308 here:

While I did peek at the controller settings once, I made no changes. I do not think mine is currently configured as a RAID, but (now that I see it is possible) I will look more closely (after current burn-in activities complete). I have had my test system filled with a number of older drives and was able to make pools and vdeves at will with no issues.
FWIW, I have an HP204 SAS controller and cables on order to try my hand at 12 Gbps SAS for my next system.
At present I've reached 9.8 Gbps over DAC through my Mikrotik CRS305 transferring from 6 5400 rpm SATA drives on 6 Gbps SAS (?) interfaces. Is this indicative of a problem? My 10G quest has been a challenge with an odd mix of 1-10+ year old gear (mostly used). But it is fun to me.
