upgraded to 11.1 and fan is going nuts

I have a dell Latitude D630. I upgraded from 11.0 to 11.1 yesterday and since then my fan has been going nuts.

As soon as the nVidia splash screen comes up, my fan kicks in, runs for about 5 seconds, stops for about 1 second, runs for 5 seconds, stops for 1 second, and so on and so on.

I look at kpowersave and see both cpus at about 800mhz occasionally spiking up to 2000 but only briefly

i have tried setting my cpu profile to powersave from dynamic but it does not seem to have an affect.

The laptop feels cool, and i even powered it off for like 15min and then turned it on to make sure it was starting cool.

Is this an acpi problem?

Not sure… but I do know that the Nvidia and fan control has been
an issue for a LONG time. While it is true that Nvidia has made
their drivers better, than didn’t prevent them from releasing
GPUs that meltdown… btw… you HAVE one of them (it’s just
a matter of time). We’re on our SECOND motherboard on our
D630… two burnt up GPUs. Make sure you’re running the latest
BIOS from Dell (if you care about ATTEMPTING to not burn it up,
it only mitigates the problem… it WILL burn up eventually).

So… having the fan come on early and often, etc… may be
a good thing.

Hrm this might be the problem

cat /proc/acpi/processor/CPU0/throttling
state count: 8
active state: T0
state available: T0 to T7
states:
*T0: 100%
T1: 87%
T2: 75%
T3: 62%
T4: 50%
T5: 37%
T6: 25%
T7: 12%

cat /proc/acpi/processor/CPU1/throttling
state count: 8
active state: T0
state available: T0 to T7
states:
*T0: 100%
T1: 87%
T2: 75%
T3: 62%
T4: 50%
T5: 37%
T6: 25%
T7: 12%

Does that mean both my cpus are set to 100% utilization? kpowersaved still says they’re both only using 800mhz. I tried to set the cpu policy to ‘powersave’ and it’s still using the T0 state.

i followed your clue about previous problems with nvidia and grabbed a beta driver taht someone else mentioned fixed their fan problem. sure enough my fan has gone quiet again! thanks

Please can you tell the rest of us where you found it? It’s driving me NUTS!

I am having exactly the same problem you describe with the following configuration:

  • Dell XMS 1330m
  • Video card nVidia Corporation GeForce 8400M GS
  • openSuse 11.1
    -> nvidia driver x11-video-nvidiaG02 and nvidia-gfxG02-kmp-default

Could you please details the steps you have followed to fix that problem?

Thanks!

bug #465655 was raised and almost immediately closed as it turns out that the mentioened driver will fix the issue and will be in the repo soon.

yesterday, executed zypper up and the new driver is installed and fixes the fan problem.

Has anyone found a solution to reduce the speed of the fan on nVidia graphics card to a normal level? This problem still exists, I have the following configuration:

openSUSE 11.1
nVidia 9800GTX
x11-video-nvidiaG02 180.44-0.1-x86_64 (latest version)

I have a fan problem on an FX5200. At startup, it screams like a fire siren. It does that for a few minutes then quiets down. Then a few minutes later, it quiets to a near-normal level. This is only on startup when “cold.” If I restart, or shut down and immediately restart, I don’t get the racing fan.

I installed 11.2 in January on my Dell Studio 15.
It was going fine but today I’ve noticed that the fan is on all the time. I am sure this was not the case up to a few weeks ago (I am not using the new laptop much, cause I still have all my stuff in the old one). This is so annoying that I would have noticed it.
My feeling is that an update last week (or maybe 2 weeks ago) created the problem.

Even if top gives CPU usage of a few % and sensors gives low temperatures (temp1= 26.8 C and temp2= 44 C), the fan is still on (it never switches off). The output of cat /proc/acpi/processor/CPU0/throttling (which I do not know what it is, btw) is exactly like above.

Any hint?
