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.

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

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.

Unbelievable! A full "good few" hours after the initial objections, in

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

It's just amazing how much nonsense the people in this group will spout.
Can't you all either answer the question seriously or say nothing?

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.");
	    return 0;
	}

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, like clockwork, Eric Sosman supplied the proof for the point

     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.

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.

No, it's not that clever.  Your refrigerator has temperature sensors and 
uses feedback to to only reduce the temperature until it reaches the 
desired point, and many laptops also do this (in order to reduce battery 
usage and noise) but almost all desktop coolers just reduce temperature 
as much as they can, so yes, the external temperature can cause this.

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).

Also be aware that the sensor temperature is not the core temperature, 
and the safe maxima described by Antoninus are core temperatures.  Unless 
you have a CPU with an on-die sensor, the core might be ten or twenty 
degrees hotter than the sensor.

My advice is: (1) clean your fans once a year or so*, (B) don't block the 
vents. (C) don't even think about it unless you get crashes.

* Don't use compressed air - it's not air, it's usually a pollutant 
petrochemical.  Just close your eyes and blow!

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

Hey, It should be

But the function tmpfile() is used to open a unique temporary file,
the file will be automatically deleted when it is closed or the
program terminates. It does nothing with temperature of CPU.

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

Oh dear, are you sure? I just ordered Fahrenheit 451 to learn

Perhaps, but it's not likely to matter.

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.

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.
