CPU temperature

English Hardware
#1

My Intel processor has dual core and 1.6 ghz freq (each core 800mhz). When I’m on openSUSE 11.4, the temperature widget I have on my desktop indicates, after 3 hours of activity, 63 degrees and sometimes even 71 degrees. Before that time limit, it goes around 55 degrees. I think it’s pretty hot, since I don’t use its brain too much. I just surf the Internet, write, deal with files. I don’t play 3d games or mess up with sophisticated graphic programs.

I’m just curious if that’s a normal temperature for the poor proc.

Hello could you see which application use more your CPU. See with ALT+F2.

#3

Hi
Are you sure each core is only 800MHz…? :wink:

Can you check whether your running at on-demand or performance with cpufreq-info


cpufreq-info

You may need to install cpufrequtils package.

#4

Does it include cpufreq.h(a library which is written in C) on it?

Here you will find it http://rpm.pbone.net/index.php3](http://www.rpmfind.net/linux/rpm2html/search.php?query=cpufrequtils-32bit(x86-32))

#5

Hi
Please explain what does a development file have to do with checking if the cpu frequency is set to run at full speed (performance) or step down (on-demand)?

#6

Dear Stamos,

I fail to see what Alt-F2 helps here. On my system it shows a tiny window with an empty text field. Nothing about how “could you see which application use more your CPU”.

I also fail to see what your question about cpufreq. h has to do with the topic here. When you want to ask off-topic questions, please start a new topic.
BTW cpufreq.h is NOT a library, but a header file.

#7

I ask about if it includes. Nothing else. Anyway if my question is wrong tell me, it is wrong and I will understand.

#8

Sorry Henk but is it illegal to ask?

If I had more usage in my processor I go to ALT+F2 and then see which program has more usage.

#9

I do not know what you mean with “illegal”. According to Greek law, Netherlands law, other laws? This is not a juridical question. We want to keep discussion here as clean as possible to have a line running as straight as possible from the question to the solution. Questions that pop-up in peoples mind while reading the thread, but that have nothing to do with the topic should go in a different thread. That is good usage of most forums, not law.

And you failed again to explain how Alt-F2 tells something about CPU usage. I told you what I get. Why don’t you explain what you get when you do Alt-F2?

#10

Thank you so much for all your swift replies!

Anyway, this is not so long after I turned on my system. I said I had the temperature issue after 3 hours of activity. Now it’s about 55 degrees.

#11

Hi
So it’s an intel atom device? What about the output from;


acpi -V

What is the trip info?

#12

OFF-TOPIC:

The Linux Kernel is written is Perl, not C++!

#13

When I want to see my processor activities, I choose ALT+F2(In KDE) and then I go here to system monitor and see which of all processings “eat” more CPU usage.

#14

I do not say that it is written in C++, I say only which programming languages I use, Linux Kernel is in different language written. Do not confuse what I write. My signature is completely clear, I do not write on it that Linux kernel is written in C++.

OFF TOPIC.

#15

If you are trying to help someone, then you can’t just say ALT+F2 and expect that to help. It does not help if you do not then provide the command. Or point to them the ICON that must be pressed.

You need to then tell them the command to type after pressing ALT+F2. OK ? Please, what command do you recommend to type next ? OR point to them the ICON that is to be pressed AFTER typing <ALT><F2>.

Do you know the command? If so, why not provide it? Or why not point to the ICON. … such a post is not helpful without that as the icon is easy to miss.

Edit - and frankly, if you are referring to KDE, then IMHO using ALT+F2 is NOT a quick way to provide the system monitor. You gave a less helpful command. < CTRL >< ESC > takes one directly there.

#16

When I do Alt-F2, I get:

Nothing about “eating” CPU usage.

#17

To be more clear, it would have been more understandable if you had shown a pix like this to follow after pressing ALT + F2 (in KDE) :

Boy is Linus Torvalds going to be surprised when he learns this! The Linux
kernel is mostly in C. The part that isn’t is written in assembly language for
the appropriate processor family. The only high-level language is C - no Perl,
and absolutely no C++.

#19

Ha, I really hope the comment on the Linux Kernel being written in Perl was ironic…

Anyway, let’s not follow stamostolias attempts to drag yet another thread into offtopic. We have a task at hand here.

#20

@stamostolias, your posts are ruining this thread.They make it unintelligible. I’ve removed them to make the thread readable. Please don’t post any more in this thread. That removes 14 out of 18 posts that are just smoke in the eyes of the OP.
