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

2 Mar 2016

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.

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

Hi Chris

Where are these being tested.... 12 Deg for the low, either someone is being a scrooge and not heating the workplace in winter or these are right out of the fridge

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 example thermal resistances given, but not for BGA,
so I just looked at a random BGA product datasheet, although the one I looked at was not 14x14mm, but was slightly larger : (
Basically we keep hitting the issue of lack of datasheets / user manuals for the BCM chip : (
I don't have a tool to measure (I could try a thermocouple or the low-res home-made thermal array cam), but might end up relying
on the temperature reported by the chip for now. Still need to download and get the image onto the microSD..

Any guess of how well (specific cooling maybe) this should work?
