 |
|
Hi. I am wondering. How long does one thermal paste/grease last for a
Pentium III 600 Mhz CPU (Katami/Slot 1)? I noticed that a year ago I
had to clean the CPU's old grease/paste and put a new supply. After a
year, my computer started crashing when in stress (e.g., compiling and
getting too hot; 106 degrees(F)).
I do a lot of compiling on this machine. My room can get very hot during
summer times (85 degrees(F)). I didn't have this problem until a few days
ago, and in the past few months, it has been very hot so it didn't just
get hotter. Even during cooler hours (at night), my computer will still
crash due to enornmous stress and heat it produces. I am wondering if
thermal paste/grease is supposed to last years.
Thank you in advance.

You might just have to accept that sometimes it is simply too hot in
your room for your computer. My apartment often hits 33'C when I am away
during the day and the cooling system for my computer just can't do
the job when the ambient temp is that high - I have to fire up the
air conditioner and wait until the temp comes down to at least 30'C. |

Yep, both power supply fan and CPU fan. Temperatures are similiar before and
after the problem started. It is the same exact problem last year before I
put a new supply of thermal paste/grease for the CPU.

Hmm, the weather and my room was hot last month too. I only get problems
if I do something intensive like compile, run cpuburn, etc. Right now, the
CPU temperature is 102 degrees(F) idled.

Still crashes even at night and the CPU temperature is in the 90s.

I would not give it more than 6 months. That is what you get whit synthetic
pastes. After changing the paste for the third time I desided to try peanut
butter. The crease in it keeps it conductive for years. Watch the chunky
varietes though.

Agreed. Also, are you overclocking ? If so, may need to slow back down.

Used correctly it lasts decades. More likely the rest of your cooling
system is underdimensioned or some other component is failing, e.g.
the PSU.

Really? And how would you know that? I don't know about thermal paste
but I know that thermal tape crap doesn't last long. I remember taking
off an old T-Bird 1.3ghz cpu where I had used the provided tape
instead of grease and the tape was completely gone (dissolved from
heat). |

Fans do work. Checked about three months for pile of dusts. I don't like
overclocking due to more problems, so no.

First people get annoyed when you quote temps in °F - it's not considered
suitable for scientific work. Are you sure your CPU is only at 106°F
(~41°C)? The Katmai 600MHz was one of the hottest CPUs for its day - it
was basically an overclocked part by Intel. Then again absolute temps from
mbrd monitors are not a good measure due to calibration differences. WHat
you need to look at is relative temps: working vs. not working?
Was that CPU a retail version with the Intel installed heatsink/fan? I
still have my retail PIII 450 and it runs at 65°C on a warmish day - say
25-30°C room ambient. I've never touched the thermal grease on it because
it looks like it is still a paste - the stuff that I can see anyway. The
lower cost thermal pastes *do* tend to separate out and bleed the
oil/grease away, particularly for the cache chips which do not actually
make direct contact with the heatsink plate - IOW the thermal paste
actually fills an air gap.

You might want to take a look at the phase change thermal interface
materials that AMD recommends for their current CPUs. Other than that
maybe a better thermal grease would work better and make sure you don't use
too much. Also, have you checked the heatsink fins are not clogged with
dust?

Tape and grease is not suitable to be removed and re-attached.
If the cooler and the power-semiconductor (CPU) are planar
enough the grease/pad will be streteched so thin that they are
invisible.
Apart from that I have now been doing electronics for over 20
years and the 80 or 90C a CPU heats up is nothing special.
Many power semiconductors are rated for up to 200C and they
are mounted using termal grease. Problems with this stuff
only happen if cooler and semiconductor are moved or if there
is a significant gap between cooler and semiconductor, which
causes "pumpout" in temperature-changes.
Power semiconductor technology is nothing new and is
well understood today.

Arno

Hmm, I didn't know that. Maybe that is why I had so many problems with heat
and CPU stress. I remember buying it the first time (yes, I even tried another
CPU) that my games and anything intensive (like CPUburn) crashed like heck.
This was on an ASUS P3B-F motherboard before swiching to my old DFI motheboard
(the one I have now). Identical symptoms.

The BIOS and softwares were the identical. Right now, almost idled
temperatures 98.6 degrees(F)/38.0 degrees(C) with:
load average: 0.12, 0.17, 0.11 ... Not working temperatures were listed in
my original posts. I don't want to compile or do anything intensive to crash
again. The system has been up for 2 days so far, pretty much idling. :)
Before the problems came back up from my compile, I had 160+ days uptime.

Fins seem to look fine. I am thinking it is the grease since it is a
repeat of the last time the grease had to be recreated.

That should not happen. Thermal grease only works well when there
is no air-gap and the surfaces are pretty smooth. Otherwise
you need to use a thermal pad that has worse thermal conductivity
but is designed to bridge a gap, i.e. will work for a longer time
in this situation. Also you have to use a pad of the kind and
thickness.
The problem is that if there is any significant gap, the grease will
dry out and shrink, which makes it ineffective. You cannot correct
this problem with better grease.
