ThinkPad Fan Control error


Please check this link for detailed information on how to control thinkpad fan speed.There are some automated scripts which can help you to control the speed.

Due to slow fan speed your thinkpad might get overheated. This is a bug. I found a very useful shell script to control the fan speed.

Hope this helps you.

    I was able to install tpfand and tpfan-admin by following the instructions posted here. However, I'm unable to finish all the instructions.

    After installing ThinkPad Fan Control I referred to the instructions again and did this:

    Now in the terminal again: Code:

    sudo gedit /usr/lib/python2.6/dist-packages/tpfand/

    A text file (gedit) opens up but the file is blank so I can't continue to the next step which is:

    Find the lines 170-174 and replace:

    self.product_id = None
    self.product_name = None
    self.product_pretty_vendor = None
    self.product_pretty_name = None
    self.product_pretty_id = None

    In addition, when I click on ThinkPad Fan Control this message appears despite being able to install tpfand:

    ThinkPad Fan Control error message

    Also, when I try sudo thinkfan I get this message:

    WARNING: Using default temperature inputs in /proc/acpi/ibm/thermal.
    WARNING: You have not provided any correction values for any sensor, and your fan will only start at 55 °C. This can be dangerous for your hard drive.

    I found this post on how to control ThinkPad fan speed for T430, but I got confused on steps 6 and 7 so I aborted my experiment to do it.

    Is there a way to solve this? I hope someone can help me.

    I'm using ThinkPad R61i 12.04 64-bit, Intel T5870 4GB RAM, 160 GB HDD.

    Thank you for this, however I'm confused on how to follow the steps from the article since I'm not that knowledgeable in Ubuntu.

    Thank you. Can I ask for clarification though? I've created /etc/modprobe.d/thinkpad-acpi.conf and added options thinkpad_acpi fan_control=1 to a blank sheet of gedit file, saved it and closed the window. I'm not sure though what Then reload the module means. Should I open the .conf file again or /proc/acpi/ibm/fan and /proc/acpi/ibm/fan? I don't know what I should do with the code ># modprobe -r thinkpad-acpi ># modprobe thinkpad-acpi Change the value of level ># echo level 7 > /proc/acpi/ibm/fan

    Once you set the fan_control to 1. You need to reload thinkpad-acpi module. So run modprobe -r thinkpad-acpi modprobe thinkpad-acpi commands. After reloading set the fan speed to level 7 using echo level 7 > /proc/acpi/ibm/fan

    This is result of running the first command: [email protected]:~$ modprobe -r thinkpad-acpi FATAL: Error removing thinkpad_acpi (/lib/modules/3.2.0-29-generic/kernel/drivers/platform/x86/t‌​hinkpad_acpi.ko): Operation not permitted [email protected]:~$

    You should run that command with root login.
