[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Thomas]

I know it is long time since this was opened, however herewith I want to
declare that this problem still exists nowadays in all Thinkpad line and
it is not related to Linux.

From all what I have learned so far there is only one conclusion:

Lenovo is gapping its fans to keep their products at low noise
intentionally with the penalty of lower performance. This problem is
getting annoying as more powerful a CPU is as it needs more cooling. No
Linux OS is controlling the fans by default and it is obvious it is not
Ubuntu or any other fault. It is simply Lenovo is hindering any OS to
use higher fan speeds.

JFYI in my situation the maximum disengaged fan in a Thinkpad Extreme is
about 7800 rpm, however highest auto level is at 4800 rpm. thinkpad_acpi
is offering level 7 max which equals to this 4800 rpm. Please note
thinkpad_acpi is depending on registers which only offer levels but no
fixed speed.

For me personally this is a bad design decision and will go into the
equation of vendor choice for the next purchase but who cares.

PS: As a last there is a pulse setup thinkable which keeps the desired
fan rpm at a certain level by alternating between full and highest, but
this is a far off topic here.

  [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

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?).

[Seth Arnold]

John, note that the 'high -> won't fix' comes from importing Red Hat's
bugzilla statuses.

Furthermore, this bug has been such a dumping ground that it's probably
best to ignore this bug entirely and file a new issue if you're still
seeing problems.

Thanks

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?).

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[R. Steve McKown]

In response to #161.  Since 14.04 at least both my X201 Core i5 and X230
Core i7 no longer reach thermal shutdown.  It appears that the reason is
that the CPUs are more aggressively down-clocked as temperature rises.

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Redfred Garett]

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.

Can any of you old timers tell if this bug will break my new Thinkpad
X201S? And I should buy Windows 10 instead?

  [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

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?).

[JohnWashington]

penalvch: do look more closely.  Ellieviolet46 is clearly a link
spammer.  If you go to the site she recommends, for a few $$ she'll
write you an essay! :)

And she's done the same on two other Launchpad bugs.  Sadly it seems
there's no way to stop this kind of thing or even report it.  See bug
45419.  And see how long THAT bug has been open and weep.  Perhaps it
will help if more people tick the 'me too' on it, for surely it affects
every one of us.

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?).

  [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

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?).

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Andre]

Lenovo R61i, type 7650, Intel Core Duo T5450, Ubuntu 14.04: my fan is
always stuck around 3000RPM, whatever the temperature. I've reached
75/80°C, which is relatively hot, considering lmsensors shows 85°C as
crit temp.

[Seth Arnold]

Anders, you can try installing the 'thermald' package; it might be a
reasonable bandaid.

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?).

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Anders Hall]

Stopped using x201. However a friend i support has x201 with 14.04 and
it still breaks badly.

because the real bug is that the bios does not speed up the fan
correctly when it does get too hot.

status:Fix Released → Confirmed

As usual faulty arguments are reason enough to dismiss bugs. It works on
Windows. It has worked better on various releases. However, no fix has
ever been released. No work (technical) has ever been made to solve this
bug. It is for sure in the design of Ubuntu and Linux drivers. The
fixes work for minor loads, though not for heavy stress on the
computer. Noise in relation to fixes is another issue.

Cheers

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Mark]

@Philipp: With my solution which works for, there is no need to run
the fan on disengaged. At the moment e.g. the fan is not running at all
and I am happy with 44° Celsius which rather low. But when I am
stressing the system more, the temperature hardly ever rises above 60°
Celsius. Then the fan is running, but definitely not on full speed.
Before that I was seldomly below 80° and I often had the system quickly
rising towards 100°. Unfortunately I can not say what really did the
trick. But I am quite sure the Bios can only contributed with a small
factor. I updated the Bios months before the other things and there was
only a little improvement. I rather suspect that installing the
installing i965-va-driver and a newer kernel did something. I suspect
this, because the overheating mostly only happened when I was doing
things which stressed the gpu (watching movies, encoding video). At
least in my installation the i965-va-driver was never installed by
default.

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?).

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Phillip Susi]

That driver allows using the GPU for video encoding/decoding, which
reduces the load on the cpu during those activities, and thus, the heat
it generates.  A heavy load will still cause it to overheat because the
real bug is that the bios does not speed up the fan correctly when it
does get too hot.

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Mark]

Incomplete is a nice decription for no one is caring.. Fact is that in
(K)Ubuntu's default installation this bug appears and is very annoying.
For me it is also a fact, that the problem can be solved, by the
procedure I have described. Unfortunately I can not tell which one did
the fix. But it means the default installation for Thinkpads can be
fixed.

  [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

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?).

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[JohnWashington]

 It isn't don't care so much as it is that the bug lies in the laptop's
bios, not linux.

I'm not competent to say whether it's in the bios, but for the sake of
discussion I can accept that.  But it's noticeable that some of the
reports here are indicating that things were better in the past, then
got worse with later revisions of Ubuntu.  Doesn't that indicate that,
regardless of where the bug lies, there is the possibility of working
around it outside the bios?  Phillip, I don't feel you should dismiss
Mark so hastily.

That all said, clearly it's a problem that will be difficult for
developers to reproduce, and which factors such as exact hardware
revision, bios revision, thickness of fluff in the fan duct (!) and much
else will all influence.  Good accurate reporting will be needed.

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Phillip Susi]

As others have noted, the workaround is to set the fan to disengaged
mode so that it runs at full speed.  As for it previously being worse;
in some cases it sounds like there may have been less dust in the fan at
an earlier time, and in others, various changes over time may have
caused the cpu to work harder and generate more heat.  The bios is
supposed to respond to more heat by ramping up the fan speed, but
reports indicate this is broken and the bios won't go over 4000 rpm
unless you override it with the disengaged state.

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?).

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Mark]

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.

[Jean Jordaan]

Thinkpad X201i, was running fine for a couple of years under 10.10,
upgraded to 12.04, now the machine is overheating and shutting down
regularly.

Overheating experienced while running test suites or while watching
video, Skype video calls, or Firefox Flash plugin activity.

  [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

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?).

[Jean Jordaan]

@penalvch, mine is not a new report, just a data point on this issue
ongoing since 2011-04-06, and before that on Bug #370173 since
2009-05-01, still unresolved.

I suspect opening a new (duplicate) bug will not help matters. That said
`apport-collect` wouldn't let me add info to this report, so I added my
info at https://bugs.launchpad.net/ubuntu/+source/linux-lts-
raring/+bug/1254576

To trigger this issue I installed Ubuntu 12.04, updated to the present.

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Alexander List]

I have been working since my first comment on this bug using the fan
speed set to max, with the result that my fan is no de facto dead and I
had to get a replacement heatsink assembly ...

I will happily test using the instructions for Jamie above, so we can
get this fixed before Saucy release ...

[Tristan Nakagawa]

I can confirm this is still happening on Ubuntu 13.04 x64 on my Thinkpad
R500. The thinkfan improves, but doesn't solve the issue, so does
cleaning the inside from dust.

I will try to install the new ubuntu release.

  [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

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?).

[Kernel-packages] [Bug 751689] Re: [Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'

[Christopher M. Penalver]

Jamie Strandboge, this bug was reported a while ago and there hasn't
been any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications-Accessories-Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux replace-with-bug-number

Also, could you please test the latest upstream kernel available following 
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional 
upstream developers to examine the issue. Please do not test the daily folder, 
but the one all the way at the bottom. Once you've tested the upstream kernel, 
please comment on which kernel version specifically you tested. If this bug is 
fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For 
example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next 
to the word Tags located at the bottom of the bug description. As well, please 
remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
