MTBF is quite well tied to a contract purchasing when you buy large quantities of components for manufacturing. Intel don't know where people are going to use their products and the range of environments they get exposed to can't be easily equated for.
I know Intel has been working for some time on the idea of high temperature data centres, this will impact the MTBF of all components but you can always calculate the cost of the losses vs the cost of the cooling: http://www.datacenterdynamics.com/focus/archive/2012/08/inte...
