Raspberry Pi: thermal images
There are some heatsinks for the Raspberry Pi and I wanted to evaluate if I need one.
So I decided to take some thermal images of it under typical load. I used my FLIR camera. Here are the first results.
After 10min in idle mode (96% idle): 39°C CPU temperature
After 50min in idle mode (96% idle): 42.4°C CPU temperature
The hottest spot is not the CPU, but the companion chip.
In the next days I will post some thermal images of the Rasp.Pi working under heavy load.
Update: 27.01.13:
Here is the stress test thermal shot: Link
[...] Here’s a great thermal imaging sequence that uncovers some interesting details about the Raspberry Pi from Zipfelmaus.com. [...]
[...] The finishing is not perfect, I am not very skilled in plastic works. At first, temperature reached 58ºC. After making some holes on top of the SoC, temperature lowered to 50ºC. I suspect that the Lan chip is hotter than the SoC, as you can see in this post: http://www.zipfelmaus.com/blog/raspberry-pi-thermal-images/ [...]
