[Bug 751689] Re: Thinkpad x201* overheats due to slow fans when on 'auto'
I have the same experiences as commetdog in comment #30 and Gert van Dijk in comment #20 The only way I can actually get the CPU cool is by running the fan at full-speed (~6000RPM). The other fan speeds only slow the heat increase. I've patched thinkfan to allow level 127 (full-speed), and (thus far) added the following to thinkfan.conf: ... (7, 54, 85) (127, 75, 32767) This means that once we hit 85C, the fan goes to full speed, and does not come back down until we're at or below 75C. And, as a general rule, those are the only two rules that get exercised by my system (T61p). ** Summary changed: - Thinkpad x201* overheats due to slow fans when on 'auto' + Thinkpads overheat due to slow fans when on 'auto' -- 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 can confirm the problem on Ubuntu 10.10 on a Lenovo W500 with kernel 2.6.35-30-generic-pae-tuxonice (and every other recent kernel I've tried). Can't boot with BIOS AC setting on Balanced, which would allow frequency scaling to kick in at lower temp to keep things cool. Temp climbs up to 90C under full CPU load, because fan never goes to disengaged mode (~4900 RPM) when set to auto.

Since yesterday I started to use thinkfan with the patch applied from the Debian bug report. This does the trick for now, but I really would like to see a fix for level auto in thinkpad-acpi. @Mikhail: It seems common that level 7 (seems the highest) is indeed only halfway the full speed of the fan on a T61p. This has been the case ever since I got this laptop for Linux (3 years now) and is also described on the Thinkwiki webpage somewhere.

[Bug 751689] Re: Thinkpad x201* overheats due to slow fans when on 'auto'
This issue is occuring for me since a very long time; using Windows the fans have a much higher speed setting compared to using Linux and the thinkpad-acpi driver. However, since the use of Maverick I experience a lot more automatic shutdowns, triggered by thinkpad-acpi, due to overheating. Before, I was using Karmic and also experienced it sometimes. When monitoring the temperatures manually and setting a fan speed accordingly the CPU is cooled properly, but thinkpad-acpi never triggers higher CPU fan speeds even when 95 °C! That is, in my opinion, a bug. I'm having this issue on my T61p - C2D T9300 w/ Nvidia QuadroFX 570M. Both need quite a lot of cooling, especially when using the docking station (less ventilation, more isolation on the bottom). That's why I don't think this issue is specific for one Thinkpad model, but occuring as soon as you start using thinkpad-acpi, also in older versions of Ubuntu. And yes, it's a universe piece of software not part of the core of Ubuntu, but this should really be fixed as it might cause hardware failures. I think running a user space software daemon as a workaround is rather 'dirty'. More hardware related, but still not justifying the behaviour of thinkpad-acpi: I noticed there was an awful lot of thermal grease on both the CPU and the GPU for the integrated heatsink/fan in my Thinkpad, I cleaned it, replaced this with a proper amount of thermal grease and temperatures are 10 °C lower since then. -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: Thinkpad x201* overheats due to slow fans when on 'auto'
@Andy, as stated, this is not a change in behavior-- maverick had the same problem of not spinning the fan high enough (only 4500rpm) when temperatures were particularly high. The difference between maverick and natty is that maverick tends to run ~8C cooler so you hit the critical 100C shutdown less frequently (but still hit it). The BIOS/EC should be handling this, and indeed it does adjust the fan speed between 0 and 4500rpm just fine. The problem is that it doesn't spin up the fans to a fast enough speed (they are capable of ~6500rpm) when under very high temperatures. Also, when Advanced Thermal Management in the BIOS is set to 'Maximum Performance' (the apparent default for this machine when on AC) the problem is especially aggravated since frequency scaling doesn't seem to occur. When Advanced Thermal Management is set to 'Balanced' (the default when on battery), cpu frequency scaling does occur, which helps with overheating but there are still cases where the CPUs are at their lowest frequency and the fans at their BIOS/EC maximum speed (ie 4500rpm) where the temperature still goes up and you hit 100C. I have an up to date BIOS/EC according to the Lenovo website. The 'Maximum Performance' vs 'Balanced' might be as designed, but clearly there is a problem when the lowest cpu frequency and the highest fan rpm in the default install is not enough to keep the machine from hitting 100C. While the fix should probably be with Lenovo, perhaps there is something we could do in the driver when i7s hit 85C we should spin up to level 7 (otoh solution). ** Changed in: linux (Ubuntu Natty) Status: Incomplete = Confirmed -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I went poking around the BIOS (I also have the most up to date BIOS for my x201s: 1.34) and noticed something called 'Advanced Thermal Management'. It was set to 'Maximum Performance' when on A/C. I changed this to 'Balanced' (which is what is used on battery) and the situation is considerably improved, but not solved. I have gathered more information: Fan speeds (observed by setting the level manually in /proc/acpi/ibm/fan): auto: ~4500rpm max (but may be lower depending on temperature) level 6: ~4500rpm level 7: ~5300rpm disengaged: ~6500 CPU speeds: lowest: 1199 MHz highest: 2134 MHz To monitor: $ watch -n 0.5 'cat /proc/acpi/ibm/thermal ; cat /proc/acpi/ibm/fan | egrep (speed|level): ; cat /proc/cpuinfo | grep MHz' Eg: $ watch -n 0.5 'cat /proc/acpi/ibm/thermal ; cat /proc/acpi/ibm/fan | egrep (speed|level): ; cat /proc/cpuinfo | grep MHz' temperatures: 65 0 0 0 0 0 0 0 speed: 4501 level: auto cpu MHz : 1199.000 cpu MHz : 1199.000 cpu MHz : 1199.000 cpu MHz : 1199.000 Kernel thermal zones: aiui, this controls cpu scaling: $ cat /sys/class/thermal/thermal_zone0/trip_point_* 10 critical 91500 passive When set to 'balanced', the BIOS will scale the CPU back way before 91.5C (at 83C it immediately scales back to 1199 MHz). The trip point appears to not mean anything (except to suggest that things aren't critical until we are at 91.5). I turned thinkfan off and set the fan to 'auto' (the default) and I then went about trying to stress the machine: $ apt-get install stress $ stress -c 8 -i 8 -m 8 -d 8 With this load, the system was able to manage itself ok. The fan ever only got up to 4500rpm, but when the temperature got to 83C, the cpu scaling kicked in and the temp dropped to 72C. After a bit the CPUs would go back to 2134MHz and the temperature would raise again, then the cpus would be scaled back, and on and on. So 'stress' was not good enough. What was good enough was doing 3 builds of kde4libs/amd64 concurrently (in an ecryptfs encrypted HOME). After a rather long while (ie all the dependencies are installed, configure is done, the .moc files are generated and the compilation kicks goes for several minutes), the 4500rpm speed of the fans with the CPUs all at their lowest speed is not enough and the temperature very slowly rises. For now, I am adjusting thinkfan to run at level 6 (ie, the fan speed equivalent of 'auto') starting at 70C and level 7 at 85C and above (ie run the fan at the highest controlled speed (but still higher than 'auto') when the temperature is still rising after the cores are running at their lowest speed). This configuration has not been extensively tested, but I will report back if level 7 is not sufficient and the fans need to go disengaged. -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In other words, don't blame me if thinkfan breaks your system. :) -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 751689] Re: Thinkpad x201* overheats due to slow fans when on 'auto'
It looks like thinkpads have a non standard ACPI device that handles the fan control, among other things. That is where /proc/acpi/ibm comes from. It is implemented in the kernel in drivers/platform/x86/thinkpad_acpi.c, and has some comments pointing to: http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Marking critical. I have hit this bug recently in both Natty and Maverick. I'm marking critical, as this affects a) server uptime, and b) possibly can cause real-life physical damage. ** Changed in: linux (Ubuntu) Importance: Undecided = Critical ** Also affects: linux (Ubuntu Maverick) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Natty) Importance: Critical Status: Confirmed ** Changed in: linux (Ubuntu Maverick) Status: New = Confirmed ** Changed in: linux (Ubuntu Maverick) Importance: Undecided = Critical -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: Thinkpad x201* overheats due to slow fans when on 'auto'
Just confirmed in maverick that a) the same test case does not raise the temperature quite as high but b) the fan speed is still not correctly set. In other words, with the fans set to 'auto' in maverick, the fan speed still never rose above ~4500 rpm even though the temperatures were very high (~90C). -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751689] Re: Thinkpad x201* overheats due to slow fans when on 'auto'
** Description changed: 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?).

So the immediate solution is what? I chucked this into my /etc/rc.local file before exit 0: rmmod thinkpad_acpi modprobe thinkpad_acpi fan_control=1 echo level 7 /proc/acpi/ibm/fan # echo level disengaged /proc/acpi/ibm/fan # this is being problematic # echo level auto /proc/acpi/ibm/fan I ekpt the other settings just in case. -- 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: Thinkpad x201* overheats due to slow fans when on 'auto' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
