Cold weather failure Jetson Nano

My project is a field robot using a Jetson Nano. Been working on since spring 2019

I can control it at limited distance via ssh (secure shell).

Wanted to test new devices outside…went smoothly for a while then started acting erratic.

Decide to power reset… fan came on at high speed and could not control.

Pushing the robot inside I tried power reset and fan still came on at high speed.

After robot warmed up things went back to normal.

Has anyone been down this road before?

Should I be looking for an industrial sbc and if so any recommendations ?

Also should I be looking at peripherals causing issues?

Thanks!
