Hi,

First off, Thank you very much for Stella Linux. Its an awesome fork. It makes a lot of sense to guys like me who just need to have a RHEL like OS + Something that will let me play youtube videos, songs etc out of the box.

There's only one nagging issue I have and that is my laptop fan keeps jumping fro 2400+ to 0 on and off.

Temperature varies between 34C to 45C.

I had mentioned the same earlier on the forum. I tried the stuff suggested in the links, but that was not of much help.

I have a Thinkpad T430 with 3rd Gen i5, Intel HD 4000 Graphics ONLY.

************************************************************ *******************
I Do Not have nvidia graphics at all. Only Intel HD 4000.
************************************************************ *******************

Anyone here facing similar issues? Please let me know.

Also, the fan rotations mentioned above are reported by sensors (lm_sensors package. I have run the sensor-detect script and then only reporting the temperature here.).

Laptop also seems to be unusually warm.

I have tried Debian Wheezy XFCE and noticed the same Fan rotation issue.

Is the fan rotation and the high temperature (45 and sometimes 48C) something I should really worry about?

If not, I am more than glad.

Please let me know.

Hello,

Some BIOSes have features re fan speed and so on, not sure what the Thinkpad provides.
You can check out this page, see if anything there helps:
http://www.thinkwiki.org/wiki/How_to_control_fan_speed

The temperature of the CPU seems ok, if could even go a bit higher and still be safe.

Hi nux,

Thanks for the update.

I had tried the link but didn't help much.

To test if this happens with any other distro, I tried it with Debian and Ubuntu.

Ubuntu would make the fan spin at 3600 and temp would jump at 59C.

Debian Wheezy xfce (7.6) would report the fan spins and temp around the same time as Stella Linux.

I'll try installing Stella again this week.

Once again, thank you for Stella Linux. It's the best one.

What I would try is to install thinkfan and see if I can do anything with that one.
I do not have it in my repo, but I see someone has built a package for it already:

Do you know where we can find a version of TLP for CentOS7? This would probably be useful for Thinkpad owners. http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-man agement.html
Or
http://sourceforge.net/projects/tp4xfancontrol/files/tp4xfan control/
I have an X61 Thinkpad, so am interested as well.

Added tlp to my repo, try it out and let me know if it actually works.

I have installed CentOS7 on Thinkpad X61
Installed both packages: tlp & tlp-rdw
One thing I noticed is that usually there is a way to enable using systemctl
systemctl enable t[TAB] does not show the tlp service and /etc does not show config files. Not sure how to setup
sudo tlp start works but I think this is the SysV way to start it.

Since a lot of linux users use Thinkpads, I would request a few more packages that I don't think are part of the repos and 3rd party repos or yet available for 7.

1) tp_smapi http://www.thinkwiki.org/wiki/Tp_smapi
2) akmod-tp_smapi http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-man agement.html Under Fedora area
3) akmod-acpi_call http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-man agement.html Under Fedora area
4) thinkfan http://thinkfan.sourceforge.net/
5) HDAPS http://www.thinkwiki.org/wiki/HDAPS
6) laptop-mode-tools is an alternative to TLP https://github.com/rickysarraf/laptop-mode-tools
7) Another fan control alternative https://github.com/hspak/simpfand
Cool Thinkgui https://github.com/krzemin/thinkgui Linux GUI for ThinkPad laptops
9) tpb http://savannah.nongnu.org/projects/tpb/

@ pmux

Hello
The fan turning on and off seems normal. The kernel has a governor to control that, based on max temp settings. Like Nux said above, your temps are not bad.
Real expensive laptops might have variable fan speed controllers, but most I've seen are either on or off types.

Stella 6.5
Check your system for cpuspeed.
rpm -qi cpuspeed
See if it is running
chkconfig | grep cpu
cpuspeed 0:off 1:on 2:on 3:on 4:on 5:on 6:off

There is documentation to explain the options you have. You can do things like set the temp where the CPU goes to minimum speed and such.
cpuspeed -h
man cpuspeed

--------

@ Anonymo
I don't know if it would make any difference on your system, but have you tried enabling cpupower service? (or maybe it's already enabled?) You can tweak some settings.
systemctl start cpupower.service
cpupower frequency-info
man cpupower

Thank you for the suggestion. I will try it. I'm also making suggestions because CentOS 7 can be a great desktop/laptop and Thinkpads are what a lot of users have.

Good job! Smile
Those of us without thinkpads will have to follow your lead. We have no way to test anything.
