Thinkpad Fan Control

Hi guys, I am a recent convert from Ubuntu now running Tumbleweed/gnome on a Thinkpad T400 with AMD graphics. Almost everything is working great, and I am absolutely loving GNOME 3. After much fiddling around I finally gave up on trying to install the proprietary AMD driver and stuck with the FOSS version, despite the serious flickering issues. My only problem is that after about 30 minutes of heavy usage (full screen flash video will do it 100% of the time) the temp will reach 100*c and then the laptop will automatically shutdown without the fan ever kicking on. Under Ubuntu I never had these issues, but I was also able to use the proprietary AMD driver.

I have tried installing tpfand and tpfan-admin, and while they run with no issues I can’t seem to change the fan speed. Even running “echo level 7 > /proc/acpi/ibm/fan” does nothing. Is there any support for fan speed control on the IBM/Lenovo Thinkpads?

Here is the relevant log snip:

I posted a response to your question in the Laptop forum. Please don’t ask the same question in more than one forum.

Thank You,

buddy, I understand it’s not so cool that people post all over the place and its definitely super nice you provide a reply, but if you do it like this, without a link to where you have put your reply, it makes things a bit complicated for those of us searching for the answer… this is just a brutal cutoff and now I gotta go back to searching. ok to be grumpy when being helpful, but go all the way and post the link next time PLEASE! :wink: Share your brains! thanks!

Let me say that we discourage double posting of the same question, I am unlikely to cross link the requests, we have a wonderful search system for all posted problems, you and every user may post a new question for any problem you wish and as a Global Moderator, here in the forums, we have the last word on the subject.

Thank You for using openSUSE,
