I have the same issue, Samsung 850 Pro.

 

So, just to clarify.... my 850 Pro is probably OK and not actually overheating all of the sudden... it never ran above 45ish prior to this update. Should I attempt to mitigate the error or wait until the update and just assume all is fine until then?

 

It's probably fine. The true temp is 100 minus whatever you see in the UI. So if the UI shows 65, the real temp is 35.

OK, all looks good then. 35 as per normal

I have the same issue with my Samsung EVO SSD. Its showing 75 degrees where used to show like 30.

Question is which is correct?  Hit with some heat and see if the temp goes up or down.  Prob will go down.  We're preparing -rc13 release to correct this.

This is why i suggested that they change it to a user selectable option. As there are too many scenarios now.

UnRaid Admins should be able to select a non-default SMART attribute per drive

My Samsung Cache Disk is showing 76 Celsius. I've put the server to sleep now....

Add me to the list of  Samsung SSD 850 EVO 500GB owners who now has a 73C overheat warning.  Is there anything we can do in the meantime other than lift the heat thresholds to suppress the alerts?

my temps look fine here ... my 850evo is an UAD actually ...

 

My two cache disks (Intel SSDSC2BW120H6) now showing 65C (before rc12 it was around 30C)

My 2 SSD show high temp in Dashboard, but UD shows normal temp.

I don't know if this is only related to rc12 but my dmesg gets filled with:

[  454.808118] ACPI Error: SMBus/IPMI/GenericSerialBus write requires Buffer of length 66, found length 32 (20170531/exfield-427)
[  454.808125] ACPI Error: Method parse/execution failed \_SB.PMI0._PMM, AE_AML_BUFFER_LIMIT (20170531/psparse-550)

EDIT:

Just found reports in rc8 with this issue.

Thanks John

 

Edit:

 

This only partially solved the issue.

 

Now I wont get error when running "sensors" manually but I still get the error every 10 seconds. Is there any new mechanism that tries to read ACPI interface?

Solved: 

Had for some reason "acpi_power_meter" module loaded. When I removed this it all worked as expected.

Since this release my SSDs (not that hot in reality) are reporting as 68/69ºC ... and I can't bring up their normal SMART attributes.

 

smartctl correctly reports line 190 as 31ºC

 

smartctl -a /dev/sdf

190 Airflow_Temperature_Cel 0x0000   100   100   000    Old_age   Offline      -       31

 

Another Samsung SSD 850 EVO 500GB temp reading error, both of mine now have a 74C overheat warning and never went over 30C before update.

Everybody who sees high temperatures (specifically on Samsung drives), it is a known issue and will be corrected in rc13.

 

I have a Hitachi drive "HTS543232A7A384" showing as 75 on the dashboard but the smart attributes shows 25...
