Operating Temperature limit testing on LP V1?

Has anyone run operating temperature tests in an environmental chamber on the LattePanda V1 4GB/64GB? The temperature specifications are -10C to +50C. I'm going to run a chamber profile that tests to those limits on a couple of boards while monitoring for continued operation and hot spots (with FLIR and thermocouples). Then I want to run a margin test that will step the chamber temperature to about -20C and to +60C to see where it stops working (assuming it worked at the specs of -10C and +50C.

I'm curious if anyone has done any of that, your results, and what happens when the board begins to fail. I am interested in the Intel / Windows part specifically, not Arduino.
