CPU Temperature WAY too hot (Pentium D 830)

Hi,

This was originally posted on the alt.comp.hardware forum but I am
copying it here for more help:

Here is my original message:

**********

Hi,

My computer specs are as follows:

OSes: Windows XP Pro
Motherboard: ASUS P5ND2-SLI
Processor: Intel Pentium D 830 3.0GHz (not overclocked)
Hard Drive: 250GB SATA
RAM: 2x 512MB DDR 667MHz
Video Card: ATI Radeon X1300 PRO
Optical Drive: Pioneer DVR-110D DVD-RW
USB: 4x USB 2.0
Sound Card: 7.1 Channel
Ethernet Adapter: Intel 10/100/1000 Gigabit

I dont know but I think my Pentium D 830 is too hot. Upon startup
(after being left off for about 10 hours), the CPU temperature is
around 45C (celsius) and steadily rises to about 70C. Even when I'm
not doing anything on the computer the temperature varies from 70C -
75C. When I am doing stuff, playing games, browsing the net, etc. the
temperature is around 75C - 81C. When I am doing big multitasking, the
temperature varies from 81C -86C. Is this normal? I know Pentium D
chips are hot but are they supposed to be this hot?

I checked the temperatures using ASUS PC PROBE 2

Thanks

All the replies stated that the CPU temperature was way out of whack
and that I needed to lower it immediately or my CPU would fry. Here is
one example of the response I got after posting:

**********
Sounds pretty hot to me. The processor will throttle itself if it gets
too
hot, so you shouldn't damage the processor running it this hot, but
you will
shorten its lifetime! Have a read through this:

http://www.heatsink-guide.com/maxtemp.htm

Open the case and clear all the dust and debris fromt he CPU heatsink.
Its
also worth running with the side off your case for a while to see if
the air
temperature inside the case is pushing the CPU temperature up. If
running
for a while with the side off makes the CPU cooler, then you need some
case
fans, or better air flow through your case.

***********

I gave them a report of my fans here:

1) Power Supply Fan
2) GPU Fan (on the graphics card)
3) CPU Fan @ around 4115RPM
4) Case Fan (attached on the inside of the case)

It apparently wasn't enough help to determine the cause. I checked the
temperatures using 4 tools: PC PROBE, the BIOS, SpeedFan, and EVEREST
Home Edition. BIOS, PC PROBE, and SpeedFan gave me the same results
but EVEREST readings were about 30C cooler. I later determined that
the readings on EVEREST were wrong.

Here are the fan settings on PC PROBE:

Enabled?-------Sensor Name---------Current Value----------Threshold

Yes--------------CPU-----------------------4115 RPM---------------1000
RPM
No---------------CHASSIS----------------0 RPM---------------------1000
RPM
No----------------POWER------------------0 RPM--------------------1000
RPM

Apparently, there was nothing wrong with these settings. I also
noticed a slight sound of what sounded like a wire caught in the fan
(I think..... not sure). I described it in this post:

*********
I have noticed something though. Before from
when I got the sytem to 3 months ago there was a sound of something (i
am assuming its a fan) that revved up and down. Now, the fan noise is
consistent and stays the same. Maybe, just maybe the system was a bit
louder before.

I honestly dont know. What do you think? I checked on the ASUS page
for my motherboard and there is nothing about cooling issues or
anything.

No one was able to find the cause yet, so I uploaded some pictures to
help. Here are the links:

IMPORTANT NOTE: These links dont work by clicking on them. If you do,
you will get a "403 Forbidden
You must supply a local referer to get URL '/*.JPG' from this

by using links. To solve this problem you have to cut and paste the
links into the browser for them to work.

This is the feedback I got from the people after seeing the images:

They did not work previously doing as you suggested but the
following links do work.

The side fan is installed backwards, BUT while it might help
to do that, I don't expect it to help enough.

I can't see the finer details, is there ample air intake?
If there is not, flipping the side fan will have more of a
benefit but you ought to also find a way to get more front
intake to cool the HDDs better.

I was also interested in the inside front wall of the case,
directly behind the "front of case" shots you linked above,
since there is a double wall of plastic then metal, there is
a double opportunity for the case to impede airflow.

Some of the pictures are a bit too close and too fuzzy to
get a good idea, but it might also be the dark colors of the
case.

It looks a little bit like it's really clogged with dust?
That might be the problem.

What about a rear case exhaust fan, below the PSU exhaust
fan? That is recommended by Intel & AMD... and the case
should have one, ideally.

Overall I would say the case "might" not have very good
front intake, but mostly it looks like dust in the heatsink
is to blame.

I replied:

*********

OK, as a first step, this is what I will do over the weekend: First, I
will open up the case, bundle up the wires a little more neatly, clean
out all the dust, and possibly, install the side fan the correct way.
After, without closing the case I will run the computer to see if the
temperatures are reduced. If they are, I will see if I get the same
results with the side of the case closed. Will it help? Also, I
checked and there is no rear exhaust fan. If cleaning everything
doesn't help, I guess I will have to add some more fans and maybe a
better cooler (Zalman it seems is good) for the CPU. I will report to
you everything I find on Monday (or maybe earlier). thanks for the
help, everyone (especially kony)

**********

They replied:

**********

Bundling wires would be mostly a vanity thing, since you
have the window, as it is not a serious impact on cooling,
nor are parallel ATA cables as some in the past have falsely
assumed (unless they're literally draped overtop of a
heatsink).

Dust, definitely clean it out. Cleaning out the CPU 'sink
is priority #1. If it is as bad as the picture suggested,
that may completely resolve the problem, but even if it
does, I would still consider flipping the side panel fan
around if you feel there is enough front intake to keep the
HDD(s) cool enough, since flipping that fan will impact the
airflow past the drive rack.

A good (better) heatsink would keep the CPU cooler, but the
retail 'sink is sufficient in keeping the CPU significantly
cooler than it is, especially at the (low) room temps you
reported. Replacing the heatsink would be better tailored
to reducing noise, if you felt the retail heatsink was too
loud.

**********
So pretty much they say this is what I have to do:

1) Get a can of compressed air, blow all the dust out
2) Remove the heat sink. Blow dust out of heat sink and fan.
3) Scrape off all the old thermal paste
4) Apply a new coat of thermal paste
5) Reattach heat sink
6) Start the computer without closing case to see if the temperature
goes down
7) Now close the case and see what the temperature is, if it went
down, problem solved!

As an extra precaution, I am also going to bundle the wires. This
sounds simple to do, but I really need help and step by step
instructions for the removing heatsink---scraping thermal paste-----
applying new thermal paste-----reattaching heatsink part. Thats where
I leave it off to you guys.

Thanks

Oh by the way, if you want to see the original thread go to:
http://groups.google.ca/group/alt.co...51c934e2dfcdaa

I have the same PentD 830 processor but on an Intel D955XBK mb. I also
had temperature problems with it at first.

My only thoughts are that the thermal paste is improperly applied. Too
much paste is just as bad as too little. When the paste instructions say
to properly clean the surface and use a little bit they really really
mean it. I used Arctic Silver 5 which has very specific instructions on
how much paste, how to clean the surface and how it apply it for the
PentD processor.

Doing this allowed me to run around 65-70 degC max during stress tests
and video rendering.

Secondly, I had my local machine shop (I'm lucky, it's down the hall),
mill out a new hole in my aluminum side panel so I could install a 90
CFM 120mm fan (http://www.thermaltakeusa.com/dcfans/led/bluesmart.htm)
in the side. The new fan and heat sink fan line up so the new fan blows
outside air directly to the heat sink fan.

This dropped the temps to about 55 degC max during stress tests and
video rendering. During idle I'm at 30-35 degC or even lower.

BTW, your voltages look really screwy, but someone smarter than me will
have to comment on that.

Thanks. I'll clean out the dust first and then take the next step from
there. I'll check on the voltages. I didn't change the voltages, these
are the default.

I checked the voltages....Apparently they are normal.

Oh, I cleaned out all the dust. Now, the CPU is around 45C and idle
and doesn't go over 52C no matter what I do. Is this stable?

Thanks for all the help
