They never built any Smartphone that does not throttle under full load?
Sorry, my misunderstanding. I thought you said ptitseb had been using it at max speed without it throttling, but now that I reread you only mention that it didn't immediately throttle, not that it doesn't eventually. I'd be interested to know how long it does take: is it minutes? Hours? What is the max clock speed it can run at that doesn't produce more heat than the case itself can absorb?Well, I am pretty sure it will be impossible to keep it running for an extended period of time with full CPU strength
My Pixel 2 just shuts down. Of course, this was with a vent-mounted holder while I was driving with maps up in the middle of winter and the heater cranked as high as it would go, so that may be on me.They all throttle when the CPU reaches critical temperature
Bro, plastic also conducts heat, albeit slower
Ok, let me ask different: there is no modern Smartphone that has a thermal solution that is powerful enough to run the CPU for a long time under full load? Like a normal PC can for instance? Or asked the other way round: all modern Smartphone CPUs are basicly to powerful to be built in such small devices?Of course they throttle. They all throttle when the CPU reaches critical temperature. But until that happens, they will heat themselves up - and they can get pretty warm in your hands

Normal PCs can't even, at least with the stock cooler. I updated the cooler on my six year old 65W Pentium server with a modern day 110W cooler and now it mostly doesn't throttle, but it does still momentarily drop the clock to half, according to my script that checks temps and clocks once per second.Like a normal PC can for instance?
If the tape contacts both the USB shield and the heatsink nothing prevents adding an exterior "USB" radiator.
Just a dummy copper plug (that doesn't short out the USB 5V) with fins.
Could even make a larger version that powers a tiny fan from the USB port but I doubt it'd be necessary.
Want to do a build or play heavier games? Plop that radiator into the USB port.
Need to store the Pyra away or just surfing the web, remove the external radiator.
It'd be similar to water-cooled laptop docks.
...but something much smaller than the Asus GX800.
Well, how big should be a cooling soluion to handle a recent high end Snapdragon SoC for instance? Would it fit in a 10" Tablet at least?
That's easily achieved/designed. The crux is to design the cooling solution, so that that stable point occurs at a desirable temperature - say somewhere below the SoC's temp.-cap.To be able to FULLY cool the SoC, the emitted heat has to be AT LEAST as much heat than the SoC produces.
(and of course the heatpipe needs to be capable enough to move the needed amount of heat from the SoC to the heatsink).
