Thinkpad T500 fan control, what is best way to control
Hello,
I have had my thinkpad for just a few short months and, it must be that we are heading into summer, but I am starting to finally run into some overheating issues especially when compiling software for awhile, i.e. kernel. My question would be, "Is it best to let the built in thermal management take care of the issue, and I just need to know what to tweak, or to put on a script solution such as the tp-fancontrol script? The computer takes about 5-10 minutes to overheat and the message I get in /var/log/messages is "logger: ACPI group thermal_zone / action THM1 is not defined" then it shuts down. So, any pointers in the right direction would be appreciated. I am running slackware-current x86_64 on a Lenovo Thinkpad T500. Thanks for your help, Troy |
Please post the output of following commands:
Code:
ls -1 /proc/acpi/thermal_zone/THM1 What is you Slackware version ? Which kernel do you use ? Is this kernel shipped with Slackware or compiled by yourself ? [EDIT]And yes, you can try one of the scripts proposed on this page. Some people are not happy with built-in thermal management and try either to slow down their CPU and/or GPU or to accelerate their fan. |
Sure Didier,
Here is the output Quote:

Also, running slackware current x86_64 up to date from 5/19, so I guess right at the moment slackware 13.1 Also, I have the most current bios installed as well. Thanks, Troy |
Well, I have the same output on my Thinkpad T61 (very similar to T500 only older), but the temperature (45°) but that's normal as my machine is almost idle.
Only to make sure, please send output of following command too: Code:
zcat /proc/config.gz|grep CONFIG_ACPI Code:
bash-4.1$ zcat /proc/config.gz|grep CONFIG_ACPI |
Didier,
Looks mostly similar. Here is mine: Quote:

Thanks, Troy |
I have theses lines and you don't only because some features are available only on kernel newer than yours (I'm running 2.6.35-rc1 at present) so that's normal.
I'm running out of ideas so may be you could try one of those scripts. Maybe you can check fan speed first to see if it increases when temperature does. You can "cat /proc/acpi/ibm/fan" for that. |
I use tp_fancontrol script on my T42 BUT it doesn't say it supports anything like T500 so be very very careful what you run or you could kill your cpu.

Didier,
Thanks for the suggestion. Running a kernel compile and watching the tmp of TMP1 and the speed in the fan file, even as the temperature reaches 96 degrees the fan has only gone up 50 rpm. At it seems to hover around 3000 and 3050 rpm, which obviously is not going fast enough. When I add Quote:

Dive, thanks for the suggestion, that is why I am trying to avoid doing any scripts because I don't see where the T500 is directly supported by any of them. I was just hoping for any suggestions from anyone that may have it working without having to resort to the scripts out there, with summer and code needing to be written, might not be any other option. Hopefully somebody else may have a suggestion. Thanks so far for the ones I have received. --Troy |
Do you have the fan module loaded?
