I accept all that.  I expect the power supply itself to be fairly
robust.  I was quite happy that it lasted as long as it did.

My concern is more for the other components in the system being
subject to the on-and-off heating and cooling of the circuits.  In an
earlier age of computing, this could cause the solder points, the PCBs
themselves and even the chips to crack, and thereby malfunction at
random.

I had heard of this happening around ten years ago, and it happened to
one of the learning machines we used at UCSD - the Terak workstations
we used to take Ken Bowles' Intro to Pascal class.  One of the systems
had a chip that cracked and it took Terak about four months to figure
it out.

All moot at this point.  I was just curious if this might have an
effect on the way ffmpeg really exercises the CPU cores and possibly
the disks as well.  It is one of the few apps I've used hat takes
advantage of all cores available.

Thanks..
