[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
Vacuum cleaner fixed the problem for me. My Thinkpad x201i was reaching 100C temperature regularly after only a few minutes of full load. I removed keyboard and cleaned the cpu cooler with a vacuum cleaner. Maybe it could be done by cleaning the cpu cooler venhole only from the outside. Now I never reach temperatures over 85C even with closed lid in the docking station and after prolonged time on full load. Standard cpu temperature is ~ 60C. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

+1 on Vacuum cleaner fix! Thinkfan still has to disengage for high loads, but during summer it got to the point where the T410 would regularly throttle the CPU down to 1.2GHz cause of to much heat.

Hi, I have the same problem on my TP R60. Adding (127, 66, 32767) at the end to /etc/thinkfan.conf lead me to have the fan running at disengaed by auto. This results in seltem having temparute over 85°C. Further I found, that the VID is to high by default. If I set the governer to userspace 1.833GHz and reduce the VID using wrmsr -p0 [1] 0x0199 0x0b20 The temparature goes not over 65°C. The governer ondemand switches the MSR 0x199 between 0x0613, 0x081c, and 0x0b28. This 0x0b28 should be reduced to 0x0b20 and every thing would fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
I did another run without thinkfan and manually set the speed to disengaged Top was 100°C and 4972rpm. I watched the output of the script closely and I notived, that around 95°C the CPU throtteling kicks in and lowers the Speed from 2,6GHz to 1,2GHz. At atound 85°C it goes again to 2,6GHz. So the CPU goes faster and slower as temperature rises and falls. I guess I can kill my system faster by using GPU in addition (by just browsing the web...) I assume that eventually at 95°C the thremal throtteling of the CPU speed is a tick to late and the fans dont respond in addition not quite as swiftly to deliver those 4970tpm that causes the 100°C. Which leads to the emergency shutdown. From my point of view, the system is in constant thermal edge as it has to lower its speed due to overheating. I would love to see the system not exceed the temperature which would lead to speed throtteling. Which leads to the question, can a faster fan speed meet such a desired temperature and the ultimate question, why does the fan not go faster? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
Found this bug and I think I have something to say, or watch this topic. I am using a T430 with Nvidia display. When I first installed Ubuntu 12.04 I feel that the fan is really blowing out hot air, but I can't comment on the fan speed. After I installed Bumblebee (https://wiki.ubuntu.com/Bumblebee) (a replacement for Nvidia Optimus), it seems to be able to switch off the Nvidia card so that the temperature is lowered greatly. But if I run `optirun glxgears` for about two minutes, the display card is working and the temperature rises, according to `/sys/class/thermal/thermal_zone0`, to at most `55000` (55 deg Celsius?) and the fan speed is around `3800`. Normally the temperature should be 45 and fan speed 3400. I am not really sure, but do all of you have the problem because of the Nvidia card being kept on? I don't seem to get the problem normally. (Well, the hard disk DOES get hot... but the fans doesn't seem to really help, though it seems a little bit hotter than in Windows?) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[I am not a dev] I would say that the report is not imcomplete, but rather fixed. I had this bug for a long time, but since oneric there are no problems at all.

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
May be, in the past that was something that helped me, you should check your startup-logfiles for messages that indicate problems with the graphic driver. I am not expert, so I can not tell you exactly what I did, but it turned out that Ubuntu used a fall back graphics driver instead of the real one, which caused the system to be slower and also caused the overheating. I can not remember exactly, but in one Ubuntu version I googled the error message and found instructions to fix it. In another version I just learned about the xorg-edgers-ppa with the newest versions of graphic drivers (and also fresh kernels). That helped very much and I am running them ever since (but on my x201 I do not have over heating without xorg-edgers) You may also check, if your system is using Thinkpad-ACPI instead of ACPI. This should happen automatically. Otherwise you need to enforce it on system startup. Do not ask me exactly where, just google it, that was what I did. What also helps temporarily: Remove the battery if you work on AC. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
I've been testing the following work around:
1) Set the thinkpad_acpi module to allow manual fan control (put the following
in /etc/rc.local and run as root):
rmmod thinkpad_acpi
modprobe thinkpad_acpi fan_control=1
2) Run a script from cron every five mins to set the fan to disengaged if temp
exceeds 80C
cat /usr/local/bin/temp_mon.sh
#!/bin/bash
temp=`grep temp /proc/acpi/ibm/thermal | awk '{print $2}'`
if [ ! -f /var/run/temp_mon.state ] ; then
echo auto /var/run/temp_mon.state
fi
state=`cat /var/run/temp_mon.state`
if [ $temp -gt 80 ]; then
echo -n 'level disengaged' /proc/acpi/ibm/fan
if [ $state != disengaged ]; then
logger Fan state changed to disengaged
echo disengaged /var/run/temp_mon.state
fi
else
echo -n 'level auto' /proc/acpi/ibm/fan
if [ $state != auto ]; then
logger Fan state changed to auto
echo auto /var/run/temp_mon.state
fi
fi
3) put the following in /etc/cron.d/temp_mon
*/5 * * * * root /var/run/temp_mon.state
4) Test with something like yes /dev/null and watch for
temparature/fan changes.
This isn't ideal, but it does allow a compromise between fans always
spinning and thermal shutdown. Let me know if you see any issues with
the script (code at https://github.com/theothertom/thinkpad-temp_mon)

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
Something has changed in the newest Ubuntu 12.04 kernel. Now it is possible to set up Thermal Management to Balanced when on A/C power in BIOS without making Ubuntu unbootable. This setting solves the overheating problem but you will loose some performance. Details below (Thinkpad T500). 1. Running stress -c 2 -i 2 -m 2 for several minutes now. 2. Temperature is not exceeding 65 degrees Celsius. 3. Thinkfan is on default settings. 4. CPU Frequency Governor is switching frequency between 800 MHz and 2660 MHz in about every second. I think point 5. helps. When Thermal Management is set to Maximum Performance you always run on 2660 MHz when on A/C and under heavy load. This eventually leads to emergency thermal shutdown. The problem is still not 100% solved. In Windows you can easily set up Thermal Management to Maximum Performance and never suffer from overheating.

For the record; this problem has gotten worse for me in Ubuntu 12.04. Ubuntu bug-logs are filled with silly cleaning operations from admins (fix released/confirmed/closed bla bla bla post) compared to the actual interest and severity. If some of that time pushing buttons were spent at fixing things we could see an ~50% increase in production of Ubuntu. This is of course not entirely fair, at times it seems very competent persons are at the job. Though often they vanish in thin air after a few posts. An honest option would also be to add; now closing due to missing staff (by happy helping random admin guy/girl, I might be an carpenter so you know, cheers!).

Lenovo T500, Core2 T9550 2.66GHz, Ubuntu 12.04. On AC power: - running CPU intensive processes (stress, virtualbox etc.) causes T500 to do thermal shutdown in about 2 minutes, - BIOS setting balanced on AC power prevents OS from booting, - manually setting fan speed to disengaged doesn't solve the problem, so this is not fan-speed related. On battery power CPU doesn't overheat at all, even with ondemand frequency scheduler enabled. In Windows 7 running CPU intensive processes (gaming etc.) for many hours doesn't cause such problems, so it is not hardware related. In my opinion there is something wrong with CPU frequency scheduling support in GNU/Linux. High temperature should throttle CPU frequency or force using thermal-friendly frequency scheduler. Temporary workaround. Use indicator-cpufreq to throttle CPU frequency when using CPU intensive applications. Thinkfan may be also useful. When you can hear high fan speed (disengaged mode), manually throttle CPU frequency one step down. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The bug still affects ubuntu users with the latest release 12.04. My PC reboots after one minute of high CPU usage due to excessive heat ( 100°C). But I'm not sure it's only a problem with fan control. I found several interesting things: * whatever is the fan speed (disengaged and set manually to full speed with level 127) my PC still reboots after several minutes of high CPU (I didn't have this problem before 11.10) * a full battery lasts half of the time (2h to 3h), compared to what it was with ubuntu 11.10 (~5h) * looking with powertop, I see * in frequency stats: the turbo mode of both CPU are usually equal to 33% (without no high CPU usage from my applications) * in device stats: lot of my PCI Device are running at 100%, which seems important So I think we deal here with several bugs, one about the fan, but also one possibly with ASPM, which seems disabled on my computer: $ dmesg | grep ASPM [0.160380] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it Finally, I cannot say about openint the laptop and trying to remove the dust, as the computer belong to my work with guaranty yada yada. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
I also had this problem repeatingly with different versions of Kubuntu. As it turns out, the reason for this, is not the fan, but rather a problem with the intel graphics driver which is not loaded correctly. On Kubuntu I always notice it when there is a problem to activate Desktop Effects. Currently I am running Oneric and with Oneric adding blacklist intel_ips to the /etc/modprobe.d/blacklist.conf did the trick. Unfortunately I do not remember where I exactly found this trick. But it helps. Instead of having a basic 80-90 °C and sometimes more when the overheating appeared my CPU now has between 50-60°C, sometimes more, but overheating has not been a problem since then on my Thinkpad X201. I guess it will be again with the next Precise release, because new release of (K)Ubuntu always break a lot and need months until they are stable again. But for now everything is fine. I have to add that I am also running the Xorg-edgers ppa https://launchpad.net/~xorg- edgers/+archive/ppa and a fresh kernel from there. But this alone did not help.

Confirmed that this bug exists in 3.2.0-17-generic. When /proc/acpi/ibm/fan is set to auto, my x201 will overheat when running a kernel compile. The fan RPM will not increase automatically as the temperature increases. ** Also affects: linux (Ubuntu Precise) Importance: Critical Assignee: Andy Whitcroft (apw) Status: Confirmed ** Changed in: linux (Ubuntu Precise) Status: Confirmed = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
This appears to affect me on an X220 i7, 11.10 Oneiric. This bug seems to relate to the OS and not firmware for me. I was on 11.04 previously and did not have a problem. During high-load the fan would spin to a high RPM (don't know how fast since I never had reason to check it but certainly faster than on 11.10). After upgrading to 11.10 I almost instantly found that the laptop becomes too hot to hold during high-load. Agree with others finding that auto mode will only run the fan at around ~4500rpm whereas disengaged will go to ~6300rpm. 4500rpm will allow the CPU to reach ~99/100C. 6300rpm will keep it 80C while running the same workload. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I agree with KC: I didn't have this problem with 11.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
This bug has broken my Lenovo T400. I have noticed it, but didn't expect it to be this bad. I left my machine on and went to sleep, in the morning, the screen was frozen. I turned it of, but then my video card didn't work anymore. I have do disassemble my laptop and re-flow the video card using a heat gun. Until fixed, I will be controlling my fan manually. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
I had this problem on Maverick on a ThinkPad X201 tablet (computer overheating and rebooting), and as a workaround kept my computer underclocked (using the CPU frequency scaling applet for the GNOME panel). After using that way for a while (maybe for a few months to a year), I tried again a few months ago with normal CPU settings. The rebooting problem was fixed (presumably by some update): the CPU speed would now be throttled when the computer overheats (kicks in at about 82 degrees C), avoiding a reboot (when it hits 100 degrees). (Of course, the underlying problem of slow fans remains.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 751689] Re: ThinkPads overheat due to slow fans when on 'auto'
I didn't see that problem but once the fan speed had some sort of glitch and went up to some extreme loud level (way more than 5000 RPM) and then it just fell back to 0 RPM (sensors) while the temperature was at the 45°C range. Usually my x40 just sits around with 0 RPM and it's not that clean since it's been in use quite some time. No problems getting even near to overheating with that device. Well, maybe that's another thing in summer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
