Mobile phones don't have fan yet they don't have issues with overheating. Maybe it is the heat that is overrated unless you compute 7/24.

- MikusR 9y agoThey do so have issues with overheating. Thats why they heavily throttle.
- oliwarner 9y agoIt's the 40nm process of the BCM2837 SoC in the Raspi3 that really makes it so [comparatively] hot. That's stone-age lithography there. Modern phone SoCs are not only etched down at "10nm" (FinFET et al, making things seem smaller too), they also get to sink their heat into adjacent and highly conductive components like the screen and battery. Raspi3 has air on one side, and a [comparatively] thick PCB on the other. Thermally speaking, they're in different worlds.
- userbinator 9y agothey also get to sink their heat into adjacent and highly conductive components like the screen and battery. ...and the user's hand. That's a huge amount of thermal mass.
- jamesfmilne 9y ago... which is connected to a huge liquid cooling system!
- LordKano 9y ago> they also get to sink their heat into adjacent and highly conductive components like the screen and battery. And the screen provides a much larger surface area for both conductive and convective heat transfer than that little IC. His question is sort of like asking "If my Prius can get 60MPG, why can't your Hummer?"
- GuB-42 9y agoThey do, it is just that they get throttled before the temperature gets too high. Just look at all the issues with the Snapdragon 810.
- vanderZwan 9y agoMine does get very hot when I Skype, which then often starts to stutter. And putting it on a block of frozen ice (with a plastic bag around it) to cool it fixes that issue too.
