Fan goes turbo the moment I turn on computer

Dell Dimension 8200. Been a nice quiet computer for 6 years. A few days
ago, when I was out, I'm told fan that cools CPU decided to start
blowing furiously. Then I'm told computer shut itself down.

I didn't find any thermal messages in system log. Computer boots and
runs, but fan blows furiously the moment I push the power button to turn
it on.

Ran Dell Diagnostics. It passed all tests. But there wasn't a test for
the fan.

If it was a thermal problem, something getting hot, wouldn't it take at
least a few seconds for something to get hot to trigger the fan? But
this fan blows furiously the moment I turn on the computer.

Could it be a faulty temperature sensor somewhere? I wonder where the
temperature sensor is. Is it built into the CPU itself?

Chips (CPU, chipset, video processor) heat up incredably fast. Fans
do not normally send any "dianostics" to Windows unless you install a
monitoring software. Not famialar with DELLs PC but my motherbaord
(Asus) has such software. If you find none, you can try thrid party
softwre like SpeedFan.

After 6 years you may have a half a zillion dust bunnies in there so
I recommend a good cleaning first. Use a compressor if you have
one, canned air if you don't.

Do outdoors:
1) remove cover
2) shoot air through power supply from inside & outside
(a too hot PS is will turn off a system in a second or two)
3) shoot air into every fan you see (CPU, Vid Card, case fans..)
4) repeat as needed till 99% of the crud is gone.

Now what happens when you boot?

By the way, by fan going "turbo" means its out-of-ballance
causing the ruckus (and in dire need of cleaning and/or
replacement.

Say, for example, that the mechanical method used to hold the CPU
cooler, to the top of the CPU, snaps. When the cooler no longer
makes contact, the CPU would get hot instantly. Fortunately,
Intel processors have two forms of overheat protection.
THERMTRIP is a signal from the processor, which can be tied
to the power supply ON/OFF control. If the processor case temp
gets too hot, THERMTRIP will instantly turn off the computer.
That is what saves the processor from destruction.

Have a look inside the PC. Check the assembly that affixes to the
top of the CPU. It could be loose. In the case of some clever
designs of past years, some "robust" plastic was used to hold
cooler assemblies, and some of these designs have snapped, in
a small percentage of cases. I don't know how Dell designs
theirs, so have a look.

What does this have to do with the OS? NOTHING. This is a purely
hardware related question and is out of place in THIS group.

It's called "left lobe mouthatosis" - just be thankful we

David can't hear either, so our responses fall on deaf and

Ah yes, I do see on the fan what looks suspiciously like a thermal
couple sticking into the air stream. That must be the part that's gone
bad. I'll try replacing the fan.

How about trying to move you off topic post elsewhere as well?

Oh, and the response goes DOWN HERE, top poster

Ignore him. He has obviously finished his homework early today. His entire

Your question is very welcome here, except by one brain dead school kid who
has never contributed anything useful. Do yourself a favour and killfile
the little turd.

And yet even YOU can't deny that this question has absolutely NOTHING
to do with XP OS, which is what the group is about (see that word in
the title?). So you back into your corner snarling and calling me
names instead. THAT is the action of a juvenile. I don't pull my
punches and, to use a common phrase, call a spade a spade. If you
would open your eyes and use your brain you woud realize these posts I
complain about are off topic but you choose to turn a blind eye to it.
Go ahead, live in your own little world where you follow only the
rules YOU decide are correct, and to hell with the rest of society.

I tremble at the thought of your response.

Oh, and the reply goes down HERE, top poster. That's one more little
polite rule of USENET netiquette you don't obey.

I neither deny or affirm anything. According to the general usage and
acceptance of the posts in this group, the only juvenile "living in his own
little world" is you. No one else seems to have the slightest problem with
the content of all the posts that you (and *only* you) seem to have
unilaterally* decided are unacceptable. You just can't get into that
childish brain of yours that no one else gives a flying **** what you think.
The newsgroup name is microsoft.public.windowsxp.hardware. To the rest of
the world that means that this is as good a place to post questions about
hardware as any.

"Call a spade a spade". So you are a racist as well as a child.

*You might have to borrow daddy's dictionary to look that one up. I doubt
you will find it in "My first dictionary".

Look again - I didn't top post. My response was underneath the point to
which it applied, exactly where it should be.

No. This is now a colloquialism and not generally considered racist;
at leas not anymore.

In my experience, by the way, racists are generally the ones who
accuse others of being racist.

All that bluster yet you still never could refute that the FANS in the
case have nothing to do with XP. Sad, really

That particular colloquialism is most certainly considered racist. It would
get you sacked if you used it in a work environment.

But a school child has so little experience, it is a non comment.

You seem to be somewhat confused. You are confusing me with someone who
gives a shit. Like the rest of the planet, I don't.

So what if its nothing to do with XP? It has everything to do with
hardware. That makes this the most suitable newsgroup to post it. It
bothers you. It doesn't bother me or anyone else. Learn to live with it.

This discussion is closed - but like the sckool kid you are, I'm sure you'll
have the last word.
 
We saw this problem with XP and Windows Server 2003. The same PC fan works fine with Vista on the same PC. My guess is that it is related with OS and fan manufactures software.

Yes, ask in a hardware newsgroup. Since this *is* a hardware newsgroup a
better plan woud be to just ignore our resident ****wit.
