I've run CM4 at over 100degC, they still work fine. Lifetime is reduced but it gives some idea of how robust these things actually are. They will even run to 125.That seems at odds with the "under typical loads Raspberry Pi 5 will run cooler than a similarly loaded Raspberry Pi 4" from the same link.https://www.raspberrypi.com/news/heatin ... erry-pi-5/Without any cooling in place, the Raspberry Pi 5’s CPU idle temperature is around 65°C when sitting out in the open air on the lab bench.
Both my Pi 4B and 3B are reporting just below 40C at idle, just running the desktop.
That 65C is over 60% higher than either, hardly "cooler", so maybe they are saying temperature creeps up slower from the baseline on a Pi 5 as workload increases, but it's got a hefty baseline to start with.
Thinner silicon tracking, higher clock speeds, and I am not surprised temperatures are higher. If the 85C it limits to is perfectly okay for the chip's lifetime that's not problematic - Though it's sometimes hard to convince oneself of that.
