AMD cpu fairlure

Test what? Both fans are working now. The PS is putting out correct power.
The light on
mobo is green. But nothing happens. No POST. I don't have a cpu to stick
on the board.
I don't want to buy one just to test it with. Unless the owner tells me
they want to spend the
money for a new cpu to test it with, not sure where to got from here with
it.

the only other fan in this computer.

Perhaps you should actually test it...

That was actually exactly what THG was attempting to illustrate ... the
ineffectiveness of the (then) current generation of Athlon boards to
properly shut down in the case of cataclysmic failure of the CPU cooler
(i.e. if it fell off ... which has happened) The article was written
September 17, 2001

You can view it he

However, after discovering this problem and notifying AMD great efforts were
made to prevent this ... and hence newer generation of motherboards have
been updated to handle such situations. A follow up article was posted on
October 29, 2001 outlining THG's talks with AMD and the updated standards
for thermal protection required by AMD for new boards.

"Thermal Death" is now not a problem with new Athlon boards, nor many made
after AMD updated their standards for thermal overload.

Hope this helps clarify a bit.

Yanking the heatsink off a running processor is not the same thing
as a fan failure. Even if a heatsink is yanked off a running Athlon XP,
the on chip thermal sensor would probably cause almost all (if not all)
relatively new motherboards to shut the system down without damage.
The motherboard in his test was probably a very early motherboard
that may have claimed monitoring of the on chip sensor, however I
guess it did not monitor it rapidly enough.

When an AMD cpu goes due to fan failure, does it usually take out
mainboard??

thanks




it can cause thermal damage to the mainboard, yes.

Indeed! Take a look at the Toms Hardware Guide video where they take the
HSF
off a running Athlon, now that gets a bit warm, to say the least.
