I'm wondering if anyone here has some insights on how to keep my CPU a
little bit cooler without anything drastic (moding my case, for example). I
have an Athlon XP 1800+ running at 68 C at the moment. Strictly speaking,
it isn't idle, but it may as well be, and that is obviously way too hot no
matter what it's doing. During a long POV render... well, I just finished a
7 minute render, and the temp is up around 77. It wasn't always like this,
either. This is actually a fairly recent development. So, I'm asking all
of you if anyone has any ideas
a) why it might be running so much hotter (I added a new DVD/CD-RW drive
about a month ago, but that shouldn't be a problem), and
b) what can I do about it?
I've got a pretty nice Antec case, it's fairly large with two exhaust fans
in addition to the power supply fans. I've got room in the fron for two
intake fans, but I'm not sure if that would make much difference. I just
opened it up, and there are no real obvous obstructions. Things are a
little bit dusty, but I've seen much worse. Any input would be much
appreciated!

Hi Barron:
Sounds to me like the CPU cooler is running at less RPM than needed,
prehaps it's broken or hopefully only obstructed (mine needs cleaning
every 6 months: the problems of a hairy dog... ;).

I have no problem with PII 233 but facing such POV related problem I would
start from http://www.google.com/search?q=CPU+is+too+hot or
http://www.google.com/search?q=Athlon+is+too+hot

Either the heat sink needs cleaning, or the fan is slowing down, or
the heat sink isn't making good thermal contact with the CPU.
Clean the heat sink, make sure the fan is running, and put some
thermal compound between the heat sink and the CPU.

clean the heatsink, make sure the fan is working correctly, make sure the
heatsink is in proper contact with the CPU - it should be hot to the touch
(if you remove it, clean & reapply thermal goop), run it with the case open
and see if it makes a drastic difference.
first I suggest you get a second opinion on the temperature, your mobo may
be giving duff readings.

It should also be noted that the standard heatsinks for these are often
less that the best. You might look around for a better one. I seem to
remember on that is all copper veins and about twice the size of the
normal one. More surface area = more dissipation.

Thankyou for your input everyone. The problem seems to have been resolved.
There was a TON of dust in the heatsink, so I just cleaned that out, put on
a resh layer of thermal paste (Arctic Silver III, pricy stuff), and things
seem to be back under control. It idles around 122, 123 F (50-51 C), and
during a 7 minute test render it got up to 55... Too hot for a purist, but
then it has always run a little hot. At least I don't have to worry about
it melting if I let it render overnight or something. In responce to
Patric, yes I am using a better heatsink, a Volcano 6 CU+, if that means
anything to you. It's not all copper, but it is quite a bit larger than the
one AMD sent me. Voided the warranty by using it, too... Finally, I'd like
to extend my condolances to ABX, and admiration for putting up with what
must be astronomical render times on that P233!

Thats not to bad, My other halfs PC runs the CPU fan depending upon CPU
temp. It sits around 45 degrees C no matter what its doing. I would feed it
something big and let it cook overnight, if for no other reason than to bed
the thermal paste in.

As do we all :P
