Using a FLIR AX8 to test a PI 3 full load temperature

A live thermal stream of a PI 3 in operation under load using the FLIR AX8 Thermal imaging Industrial Camera

There has been a lot of talk on the Internet in various communities and forums about what temperature the PI 3 really runs at when "Under Stress" or "Normal" operation

As I have a FLIR AX8 Industrial Thermal Camera to hand, so I thought I would video the live stream from the camera and make some observations of my own.

Please be aware the camera is not designed for "Close Ups" so there is a little parallax error when I get really close but this does not distract from my surprise when observing the results

I perform a test with the PI under a normal load which is not taxing the device much at all and then I run a 32 thread prime number sysbench test to heat things up a bit... wow what a difference.

I conclude the test by looking as close as I can while retaining some focus to let you see how the temperature gradient of the main chip can deceive you and given there is only one sensor on the PI CPU chip, it must NOT be in the middle as you will see. ... https://www.youtube.com/watch?v=89r6xueqkUU
