Raspberry Pi Operating Temperature Comparison (A+, B+, Zero, Pi 2, Pi 3)

Thanks to Gareth Halfacree, whom took a series of photographs of the Raspberry Pi processor under heavy load, I think. Note there's no load on the GPU in these photographs. You can see how potentially hot each processor chip of the Raspberry Pi get. These are at stock processing speeds with no overclock and using sysbench to push the CPU.

    Hi Clem, It will be guesswork, because not all characteristics are know, but this online tool is useful: Calculating heat sinks Usually I plug in approximate values if they are not known (there are some…

    That's actually really good. Those ceramic heatsinks are (literally) cool : ) I actually have one here for another project, but unfortunately 22x22mm : ( will see if it fits. ( MPC222225T - AMEC THERMASOL…

    Hello,

     

       Is that in degrees Centigrade?

    That is some serious power emission.

    I would add a heat sink and a fan.  I would definitely not put it into one of those tiny RPi shells.

    12degC is actually the lowest temperature allowed by health and safety for working conditions in the UK

    Damn ...it felt like that sometimes when I was there ... and that was in summer.

     

    Surely you mean an inside temperature as anyone outside would get that on many days.
