RE: [MLUG - DISCUSSION] Very Hot Athlon 2000, what to do

["Hargus, Duane" <EMAIL:PROTECTED>]

Sorry to jump in so late, just got back from a float trip.  How would one
K2/550 amd work?  Can't get it to stay cool, tried 3 fans, and mother board
supposedly has the capability of monitoring temps and specs (leastways will
show it in the bios.)  By overheating, I mean cooking temps, around 85 to 90
degrees Celsius.  I am getting tired of messing around with it.

Sounds like it's time for an experiment! :-)
Now, how to generate the heat without having to risk an expensive CPU? I'm
sure I can think of something...

Well, my previous explination was a little vague.  Yes you can use air to
cool
the pelters but you need a lot of air which means either large fans or small
loud ones.  From Ian's post he said it was already loud so adding an 80mm
fan
that spins at 6000 would make it even louder.  You are right on the heat
being
disapated in proportion to the air temp.  I'm not sure about your assumption
that you can force heat into the heat sink but most of the reviews I've read
about pelters is that you can't get a good enough heat sink fan combo to
make it
work.  I'm not saying it can't be done but it is an expensive experiment.

> Well, then why can they get away with using those things with an air
cooled
system on those DC powered electric coolers? Sorry, but I'm not convinced
that
it's as simple as that. Wouldn't the heat disapated by the heat sink be in
proportion to the difference between it and the ambiant temperature of the
air
around it, and it thermal conducting properties. I would imagine that as
long as
you could provide sufficent case ventalation, you could "Draw" the heat out
of
the heat sink. Why is that not the case?

have to ventilate your case, as opposed to pumping air through a small hose.
CFM
vs GPM. :-)
> I still think that if you had a decent air flow, you'd get better results
with
one than with out, water or not, because of the thermal potential that the
junction device forces into the heat sink. Sure it generates a small amount
of
heat it's self, but no where near the amount that the CPU would produce. I
think
it might be worthwhile to try one with a decent copper heat sink that can
draw
the heat off the device. That's just what I think.
