Fans in general? I've had very little trouble with CPU fans
(fortunately - and perhaps I'm lucky) but I find failed PSU fans and
noisy (vibrating) case fans to be just about the commonest faults

hi folks,
thanks for all the responses regarding my Frodo-style
cpu-slaying with prime95!
Mary, it's great that your dell laptop throttles back the cpu when it
overheats. that's smarter than my P4 desktop with Asus motherboard,
and also smarter than the toshiba 'satellite' laptop. if you

Crazy thought here, but what if prime95 only ran at x% speed? For
example, put some hlts in there and see how that affects the CPU temp. I
think for those of us that run Prime95 on laptops find it unnerving when
the fans are running full blast all the time, and it would be cool to
have a cooler ru
As others have already mentioned, those machines would probably have died
even without Prime95. The way I have always looked at it, Prime95 generally
causes those types of (pre-existing) problems to manifest _before_ the
warranty expires, rather than after. This feature is certainly not a Bad

I'd wager that in most of those instances, the computer would have died
without Prime95's help.
Faulty CPU fans in particular... whether they conk out after a short
while or eventually, a bad fan is a ticking time bomb. Prime95 may have
shortened the life span a bit, but it was doomed. :)

here are some instances where i have damaged computers
by (capriciously?) running prime95!
1 - i just got my wife's toshiba laptop back from toshiba warranty
service. running prime95 for ~6 months on it caused the fan to die,
and then the laptop would overheat & shutdown even without prime95

You only need to do the trial factoring on the P3. P-1 testing on the
P4 also uses the
I would say it is defiantly worth it, since it looks like your P4 is not
doing P-1 by doing this first elsewhere you may find a factor during P-1 and
save your self a whole 33M LL test.
Quite simple, stop your clients, add the worktodo line for your next 33M
exponent to your Linux client.
