I have compared two moode player. Both at latest moode release.
One has a SoC temperature of 63.3°C and shows "No throttling has occured". (Pi3B 1.2 1GB with Audiophonics ES9023 DAC)
The other one is at 60.1°C and shows "Soft temperature limit has occurred" (Pi3B+ 1.3 1GB with HiFiBerry DAC+)
Both are running HIRES files for the last 2-3 hours in a pretty warm room and do have a external linear power supply.
At which thresholds a throttling occurs?
Could this mean the throttling occurred somewhere shortly in the last 1-3 hours? Or is it active right now? Than I do not get that the lower temperated one is throttled and the higher temperated not.
Would be thankful to get more info on that message and what it actually means.
:"Soft temperature limit has occurred" means it has occurred at least once since the last time the Pi was booted. Just what the threshold is for a soft temperature limit to occur depends on the model Pi and version of its firmware. I haven't found a current tabulation of the limits but in the past there were posts on the Raspberry Pi Forum complaining that at some version of the firmware the limit for the Pi 3B+ was lower (60 deg-C) than the previous limit (70 deg-C).
See the Raspberry Pi Documentation about vcgencmd which is the command moOde uses to get throttling info from the Pi. There's also documentation of the thresholds for the fan case to activate its fan.
