For me the issue is fixed in Saucy, by doing a few things. I am not sure if it is the combination or one of them did the trick: - Installing: intel-microcode -> Update of the CPU-Firmware - running thinfan with the attached configuration (note: you must look for more detailed installation instructions on the net, the sensor settings are for a X201 only. You need to adjust them for other machines) - installing i965-va-driver - I also have updated my Bios to the latest version. But this was a while ago and did not help. But it may contribute to it.
Before that I had an average temperature of 80 and quite often sudden peaks leading to 100 and a shutdown. Now I have a permanent temperature below 60 and only a few peeks above. What I am sure of is that it did not help to have thinkfan installed, did not help alone. I have to note that I am running a x201 and have an SSD. Switching from a hardrive to SSD did not change a thing. So I assume this "solution" works also with a harddrive. Before having this solution it helped to remove the battery to prevent the overheating from happening. ** Attachment added: "thinkfan.conf" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+attachment/3942865/+files/thinkfan.conf -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto' Status in “linux” package in Ubuntu: Incomplete Status in “linux” source package in Maverick: Won't Fix Status in “linux” source package in Natty: Won't Fix Status in “linux” source package in Precise: Confirmed Status in “thinkfan” package in Debian: Fix Released Status in “linux” package in Fedora: Unknown Bug description: On my Thinkpad x201s with an i7, if I utilize all of the CPUs/hyperthreads, the machine can be made to overheat very quickly. This is because of the default level setting of 'auto' in /proc/acpi/ibm/fan. On 'auto', the fan only ever goes up to around 4500rpm, while in 'disengaged' mode it can go as high as 6400rpm. At 4500rpm, the CPU continues to climb until the system is forcibly shutdown at 100C. If I reload thinkpad_acpi like so: $ sudo rmmod thinkpad_acpi $ sudo modprobe thinkpad_acpi fan_control=1 Then I can set the fan to disengaged mode manually: echo "level disengaged" > /proc/acpi/ibm/fan With this setting, I can utilize all of the CPUs for an extended time and not surpass 85C, still pretty hot but well under the 100C range. Furthermore, setting to level '7' (the supposed max fan speed) runs the fan at ~5300, well below the maximum fan speed. In maverick this did not seem to be as much of a problem (perhaps because of the lack of the big kernel lock in natty?).
