I just hope you're right about the CPUs burning up - it doesn't happen when machines are running OGR calculations, so I suspect that you just ran into a particularly badly built example.

no, it was a stock Intel motherboard, CPU, CPU fan in a standard (i.e. not cheap) case with reasonably sized power supply (i.e. 300 watts). It has the standard number of fans.
With modern CPUs one needs a great deal of care installing the heat sink to avoid overheating. A standard CPU fan is not equivalent to a competently built computer. A modern bios has the capability to switch the computer off if it detects overheating. Unfortunately this capability is often off by default, or is deliberately switched off by shoddy assemblers who do not care whether they have installed functional CPU cooling -- and they usually have not. I recently built a computer for my son. Went through two CPU cooling systems before I got satisfactory cooling with the third system Then after the a few months the rather small and fragile plastic motherboard clip that held the extremely massive cooling system against the CPU cracked, impairing cooling efficiency, and I had to take the system apart and McGyver a clip out of inductor wire. Since it has worked fine. Modern cpu cooling systems are so massive that we need metal to metal clips all the way through the mother board, but today's motherboards still come with these frail little crappy plastic clips suitable only for old style fans. --digsig James A.
