CPU temperature

[kid joe]

Hi,

Is it normal for the temperature of your CPU to increase as time goes on?

I've got an Athlon XP 2100+ and I see that the temp is now at 51C where it
used to be around 42 to 44.

Anyone have any ideas?

You could try having a look to see if the CPU fan has got clogged up
with dust - that's the most likely thing.

51 isn't dangerously high though. I wouldn't worry unless it gets above
60C - then you should check your manufacturer's handbook. Modern desktop
CPUs have a maximum recommended temperature of anything between 65 and
85 centigrade.

This is comp.lang.c, which discusses the C programming language (no,
the C doesn't stand for Celcius). Try asking in a hardware group, or
just doing a Google search.

This is easy to fix. As you know, all computers are the same at heart, and
they all contain a Thermal Management Parameter block, which is stored in a
file (as you probably know, *everything* in C is a file) and which is
designed to allow you to control the temperature of your CPU. The TMP is
really easy to use. Just open it and write the new value (expressed, would
you believe, in Fahrenheit, which makes for the only hitch, really):

#include <stdio.h>

int main(void)
{
double desired_temperature = 42.0;
double fahr = desired_temperature * 1.8 + 32.0;
FILE *new = tmpfile(); /* open the Thermal Management Parameter block */
if(new != NULL) /* careful - sometimes the block isn't available
because the computer itself is updating it */
{
fwrite(&fahr, 1, sizeof fahr, new);
fclose(new);
}
return 0;
}

Run this program, and then re-check your computer's temperature. Bear in mind
that it may take a little while for the temperature to come back down.

If you're still having trouble after that, try removing the electron pump, a
thick cable, typically black but sometimes grey, that feeds directly into the
PSU (normally found at the back of the machine); it is put there for
performance reasons, but it is a principal factor in temperature increase.

Geez. No wonder I always run hot; I thought that the TMP value was in
degrees Kelvin. I've slagged 5 processors in the last two days, just
running "Hello World" programs.

Thanks for the tip ;-)

You're not alone Lew, this ridiculous flaw in the language has
been brought up several times by several different reputable
programmers at the Standards Committee meetings. As far back as 1986
it was proposed to adopt Standard International Units into the C
Standard but the proposal was quickly quenched by the powers that be
for "historical reasons". Come 2008 and we're still destroying our 3.2
GHz quad-cores all because a handful of old fogies can't cop on to
metric.

I think you will find the manual for that CPU will say it can work up to
90C.
The thermal pad that the retail amd kits come with seems to dry out and
loose thermal contract after years. I had a 2000+ that got hotter and hotter
each summer.

The getchar() function will return the temperature at which your processor
begins to burn. Simply compare with tmp, and the pesky units problem will be
solved.

Why not having a joke once in a while? At least these answers are somewhat

If you don't see it, I probably couldn't explain it to you.

I had been about to post a fairly long screed, using concepts like
"hypocrisy" and "double standard" and "do so as I say, not as I do", but
then I realized that a) the regs would never get it and b) even if they
did (*), they'd never admit it.

(*) My guess is that you're not quite as psychotic as most of the regs,
and that you might actually get it, but, as indicated, your position
(as a reg 2nd grade) will prevent you from being able to own up.

What preprocessor symbol should I test to get correct
internationalization in the following code?

#include <stdio.h>
#ifdef WHAT_SYMBOL_SHOULD_I_TEST
#define VERB "Sod"
#else
#define VERB "Bugger"
#endif
int main(void) {
puts (VERB " off, Twink.");

OK, so now I don't know when people are being serious or not. Will the
temperature outside in the room really have an effect? I thought the whole
point of CPU cooling was to maintain a constant temp??

But, why did you choose comp.lang.c to ask this question?

Yeah, sorry, I guess it's a bit off-topic... But I reasoned that there'd
be a strong positive correlation between people that program in C and
people that understand general hardware issues.

And then asked, rhetorically:

And then, like clockwork, Eric Sosman supplied the proof for the point
mooted, thusly:

What preprocessor symbol should I test to get correct
internationalization in the following code?

(etc, etc)

No, but there's a strong positive correlation between people
who program in C and people who *think* they understand general
hardware issues. You'll get lots of answers, with little idea
whether they're right.

Try alt.comp.hardware or comp.sys.ibm.pc.hardware.chips or a similar
group. My server carries 173 groups with "hardware" in their names. You
should be able to find a suitable one. The Web is also useful for such
queries. There must be thousands of computer forums and web sites.

Perhaps also your machine is doing more work (eg. you have a virus),
so maybe look at the CPU load.

Of course. Haven't you been following the progress of global
warming the past few years? If we (collectively) don't take
appropriate steps in a few years no computers will function.

But the function tmpfile() is used to open a unique temporary file,

Theoretically yes, but since the return value isn't used I don't
see any difference.

the file will be automatically deleted when it is closed or the

Richard was pulling your leg (joking, if you don't understand that
idiom) because your question really has nothing to do with C.

Other people posted what appear to be more helpful answers, but since
they're in a forum where we don't necessarily know about such things,
there's no guarantee that those answers are any more accurate than
Richard's.

You really really really need to post in a newsgroup that deals with
hardware.

Be aware also, that to explain an eight degree rise in core temperature
the room temperature would not even have to rise by as much as eight
degrees, because the cooler becomes less effective as the temperature
difference decreases (Newton's law).

I was thinking about this on the way home from the pub last night, and
the above is probably wrong. Newton's law only strictly applies to
passive cooling, and a passively cooled system in equilibrium will be a
constant number of degrees hotter than its environment.
