My DellM90 Precision run Ubuntu 10.10, 2.6.35-22 kernel. Fun speed is always at the max value and this is boring... the "sensor-detect" return the following: To load everything that is needed, add this to /etc/modules: #----cut here---- # Chip drivers coretemp #----cut here---- If you have some drivers built into your kernel, the list above will contain too many modules. Skip the appropriate ones! Do you want to add these lines automatically to /etc/modules? (yes/NO)y Successful! Monitoring programs won't work until the needed modules are loaded. You may want to run '/etc/init.d/module-init-tools start' to load them. Unloading i2c-dev... OK Unloading i2c-i801... OK root@connardoia:~# /etc/init.d/module-init-tools start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service module-init-tools start now I don't know what I have to do... what are the needed modules that I have to load? thank you, Gianni Thank you for your work!

Do you want to add these lines automatically to /etc/modules? (yes/NO)y
Successful!

Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/module-init-tools start'
to load them.

Unloading i2c-dev... OK
Unloading i2c-i801... OK

root@connardoia:~# /etc/init.d/module-init-tools start
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service module-init-tools start

now I don't know what I have to do...
what are the needed modules that I have to load?

thank you, Gianni

However, the fglrx driver failed to work resulting in sluggish desktop performance. Thus, I wait until 10.10 release and will report on the k10temp module again. info update: the kernel installed flawlessly.

I was thinking to wait until the next release of ubuntu, which comes with a kernel version that should include the module. As you correctly assumed, it is indeed a text-readable file. I'd rather prefer getting experience in kernel compiling on a non-essential system ;-) Thank you again for pointing towards the PPA kernel - never about its existence (fairly new to this part of reality :-) ). Also I found a correlating discussion going regarding variances in reported temperatures based on kernel version on the ubuntu forums. Cf. http://ubuntuforums.org/showthread.php?t=1569161 Linerd,

That means you would have to compile a new kernel that includes this. That's well beyond the scope of what I've done before. Try opening the k10temp.c file in a text editor. If the file is readable in a text editor, then it is indeed a source file and you'll need to compile a new kernel that includes it. This page should be of some help for compiling. https://help.ubuntu.com/community/Kernel/Compile OK, I just found something better. You can try adding the kernel team's PPA to your system and they currently have the 2.6.35 kernel available which should contain the module you need. You can add the PPA to your system from the terminal with [term]sudo add-apt-repository ppa:kernel-ppa sudo apt-get update[/term] You can then install a new kernel through synaptic, or at the time of this writing: [term]sudo apt-get install linux-headers-2.6.35-20 linux-headers-2.6.35-20-generic linux-image-2.6.35-20-generic[/term] I'm pretty sure the file you downloaded is a source file for the module.

I am running into problems though. The module is not part of my kernel. I have to install it - k10temp.c I can download the file but what do I do with it? How do I reference it correctly in /etc/modules? Do I have to add the full path or just k10temp? I never have worked with kernel mode files yet. Please explain a little bit on what to do. Thank you ever so much! Cheers Thank you for this great tutorial!

I am having problems. You Say "Add the recommended lines to /etc/modules." My recommended module is k10temp which is not included in my kernel as of yet. Kernel version 2.6.32 On the http://www.lm-sensors.org/wiki/Devices website to downloading the k10temp module they give me a kernel mode file - k10temp.c Here is the problem: What do I do with it? Just place the file into a directory? Which directory? And do I have to include the full path into /etc/modules or merely k10temp? Please explain the process in some detail. Thank you ever so much! Soenke Soenke Thank you for the tutorial!

It could also be caused by bad bearings in the fan itself. I've never hear of swappiness causing fan noise. I guess it could cause some increased CPU load which could lead to increased fan speed on a regulated system.

Your motherboard may also have sensors, but lm_sensors doesn't know how to talk to them. It may be that you're just out of luck on this one. Usually there will be a screen in your BIOS setup that will display the current temperatures if you do have sensors. That's perhaps the best way to know if you even have a chance of getting this to work. One of my computers has a cheap Chaintech motherboard with no sensors. I ended up buying a manual fan controller that fits in a 3.5" bay to quiet the fans down. Not all motherboards have the sensors required for fan control.
