Intel Core Duo / Santa Rosa: Fan always at max. speed until nvidia-glx-new was installed

Bug #228358 reported by Gerd Bavendiek on 2008-05-08
Affects Status Importance Assigned to Milestone
linux (Ubuntu)

Bug Description

Binary package hint: kernel-image-2.6.24-16-generic-di


this is a Fujitsu Siemens Lifebook E8410 with Intel 965PM (aka Santa Rosa) and Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz and 4 GB RAM running latest Hardy Kernel x86_64 as of today (08-05-08).

This CPU fan goes max as soon as GRUB has taken over control. It stays max until the kernel is shut down. Being back in the BIOS the fan goes down.

cpufreq works well. Depending on the load frequency varies from 800 to 2500. The fan is always running max.

This was not the case as long as Vista was running.

There seems to be a workaround: After I installed nvidia-glx-new, the fan goes down as soon as the X-Server is started !!!

Some details:

Linux lulu 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008 x86_64 GNU/Linux

Description: Ubuntu 8.04
Release: 8.04

  Version table:

I will give more details, if the issue is worked on.

Kind regards

I also have a problem with the nvidia videocard fan running at 100% all the time.
I'm not sure how this relates to above since mine is a desktop and it is only the videocard fan that is really loud. The system fan is quiet so not an issue for me.

There are lots of links on the web to the nvidia fan issues.
Does this need to be reported as a separate bug just for nvidia cards?

I've been manually changing it like this when logged in: nvclock -f -F 60
I was going to try to write a script to throttle the fan back when logged-out, since it goes back to 100% when you log out.

My system is:
Linux version 2.6.24-16-rt (buildd@palmer) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP PREEMPT RT Thu Apr 10 15:15:40 UTC 2008 (Ubuntu 2.6.24-4.6-generic)

  Installed: 169.12+

Video Card is NVIDIA 6600GT.

There hasn't been any recent activity in this bug report and we were wondering if this is still an issue? The Ubuntu kernel team is actively working on the upcoming Intrepid Ibex 8.10 release. If you could please test the latest Alpha release for Intrepid it would be much appreciated - . Please let us know your results. If the issue still exists, please also provide the appropriate debugging information as outlined at . Thanks in advance.

I do still have the issue, but it is managed by a script that polls the temperature every 30 seconds and adjusts the fan speed accordingly using nvclock.
Sorry, but I cannot test Intrepid, the computer with the issue needs to be relatively stable.

I do not have that particular Fujitsu Lifebook E8410 any longer. So I can't retest with 8.10.
Sorry - Gerd

Hi Guys,

Thanks for the udpates. Geoff123, please let us know your results if and when you are able to test Intrepid.

Also, just a note that the kernel team will be issuing a request for testing the lastest kernel for Intrepid in the next few days. Please just disregard that request for the time being as you've already expressed you're unable to test at the moment. Thanks.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.


2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Sorry I must have missed the prior emails. I am now using Intrepid and still have this problem. I am still managing it by using the nvclock script. Please let me know what other information you might need.
Kernel is:
Linux version (root@blaster) (gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu11) ) #1 SMP PREEMPT Sun Nov 30 09:14:44 EST 2008 (Ubuntu 2.6.27-7.16-generic)
I compiled it but only minimal changes to get the "low-latency desktop" and "1000hz" settings.
Thanks, Geoff
