Very true, but some machines, like thinkpads we have some interfaces 
exposed to us to see if fans are working and we can check that against 
the CPU temperature as we load the CPU + GPU.

batch test if possible.

I'd like to be able to see if we can force it to go critical which I 
think is a failure case - a machine should not burn so hot it shuts down.
