The CPU thermal zones should only start throttling down,
When the active devices for cooling are not enough..

But your problem is different
You just put it in the closet, were it cannot get some "fresh air"  

Any CPU without the capability to cool down, will go till emergency shutdown, in this case will happen around 85C.

I have a alwinner A20 board, with cpus at 1GHz, if I push it up, they start heating,
And each time even more, until a crash, or a fire, or anything else happen..
And I am talking about a CPU that uses very low power..


But I replied because of another thing..
The zone that reach higher temps are the Zone0( CPU )
Zone1( GPU ) is usually with less temperature( this obviously, if you are not using the Graphics for GPUComputing, etc.. ).
