[RC5] CPU Temperature

Related anecdote: 

We used to run dnetc on all of the company's Windows 2000 workstations. We
had a few oddball machines (Celeron boxes, nonetheless!) that started
freezing up inexplicably. Suspecting heat problem, we removed dnetc, and the
problem went away. Rather than try to identify boxes on our network that
have marginal cooling out of hundreds of workstations, we decided to remove
dnetc from everything except IT workstations. Needless to say, my key rate
has fallen through the floor.

Now that 90% of our boxes are PIII or Athalons, with temperature alarms, I
might be able to convince management to start dnetc back up, but I doubt it.

You perchance got a source for it?

There are many better products than the white grease...in fact, if you use a
high quality paste like arctic silver II, you'll drop the temp by several
degrees, with the same fan/heatsink.
NONE of the computer sites i have seen recommend using the white grease
anymore, simply because it isn't very good.

Generally, when I have a chip overheat, it stops operating till it cools
down, or starts brainfarting, usually in the IO department. How do I know?
Fans clog with dirt from time to time, making cooling poor to non-existent.
Blow out your CPU fan assy from time to time, like every 6 months...Ive seen
this problem on machines at work as well, where the box sits on the floor
and collects rug dirt, hair, and other debris.

I have been running dnetc for a while now and I am curious about how much it
raises my CPU's temperature.  I have a Celeron 800 which runs at about 55C
without dnetc running and 83C with dnetc running.  I do have 4 IDE devices
and a floppy drive in the case.  Is this temperature too high for the CPU,
because I don't want to cause any damage to it.  
I know my hard drives get very warm from constant use but I can't move them
around because of lack of space.  Any suggestions?
There are booster fans that occupy an ISA slot that might be of assistance.
Also,the fan assy on the CPU should have a nice smear of white conductive
heatsink grease applied before the fan assy is mounted. This white grease is
available at radio shack for a buck for a small tube. Just ask for "heatsink
Thats worked for me just fine.
