OS 6.6.1 on Ultra 6 - Temperature readings incorrect
This looks to be a bug in 6.6.1 using my Ultra 6 (legacy) NAS. And I can't make sense of what is wrong: We have a ducted air conditioned house at around 25 degrees ambient My "CPU temperature" s...
Thanks for the detailed response Skywalker!
But I ran the stress test on the CPU, which would manifest in an increased temperature sooner on the 35 degree "floor" than the system temperature (the load on the CPU raises the CPU temp, which in turn raised the system temp).
As you can see, the temperature increased FIRST on the ~50 degree "system" temp as soon as I ran the test, while the bottom "CPU Temp" remained at 35 and lagged the increase.
With 25 degree ambient, 32-37 degree Hard disk drives, the NAS in a mostly sealed cabinet (with gaps at the seams and an exhaust fan), it just still seems there is something confusing?
While your system temp was rising, the DTS reading likely went from something below 10C, and eventually past the 35C artificial floor. So yes, the CPU is may be getting hotter while the we continue to show 35C. As I mentioned before, DTS readings are less accurate (with a downward skew) the further they are from their high threshold; so a DTS reading of 32C, or 22C, is essentially gibberish. And the D510 CPU in particular is even less accurate at lower temperatures than most other Intel CPUs, so the readings may not be totally accurate until they reach 60-70C, which is still well within the safe range for this chip. There are no swapped temp sensor labels, or anything of that sort.
Does this 'floor' temperature for the CPU also apply to the RN516?
Yes, it's applied across the board to every Intel CPU.
