Change the above to read "MANY systems" instead of "MANY processors".  As
you have noted, it is the bad cooling design that causes the problem...not
the processor.

So, you are saying that if I run the GIMPS torture test and my system
overheats then there "may" be a defect in the GIMPS software?

I think (hope) you mean *could*.

FWIW, I have a Dual Xeon 2.80GHz system with 2GB of RAM.  It runs my DNS
server, web server, etc.  I also run VMware and normally have at least 2
virtual machines running.  One an XP VM the other some variant of Linux.  At
times I run a RHELv4 team with 4 systems plus the XP.  During the day time I
limit GIMPS to running on 2 CPUs (hyper-threading enabled) and nice value at
19.  At night, a cron job runs and gives GIMPS all 4 CPUs and a negative
nice value.  On some summer days, since my wife is rather slim, I don't turn
on the A/C until the room temp is above 30.  My system is on 24/7.  Never
had a heat issue.  But, I do check my fans and dust out the system on a
regular basis.  Need to do that when you live in Taipei and you have 3 house
cats.

Sorry, I don't buy into your theory that overheating may be hinting at
"software with defects".  IMHO, if that were the case the virus/hackers of
the world would be putting out "defective" code with the goal of burning up
everyones systems.  :-)
