Joel,
I would suggest you contact some materials type people. From my limited
understanding, it isn't so much how cold these things get (maybe your
application is outside this assumption), rather how the temperature is cycled.
The heat up and cool down rate will determine the thermal stress to which this
source is subjected. If you were placing the source in liquid Nitrogen and then
putting it in liquid water or a flame the stress would be much more significant
than maintaining the temperature or allowing it to heat gradually.
The Materials people should be able to help you.
