XPS 9360 CPU temperature

  • Hi guys,

    I'm getting temperature threshold warning and after installed lmsensors I have realized that under not heavy CPU usage (10-15%) temperature is about 55º.

    When launching virtualbox temperature is about 85º...

    I'm worried about this. 

    How should I proceed?

    Regards,

    __Julio

  • I'd like to get more info on regular temp too, my laptop is burning 90% of the time (3 chrome tabs & htop opened, that's it).

  • Yes, me too ! I'd like to know what to do: (here for XPS 13 9350 DE running ubuntu 16.04)

    as soon as I do some CPU intensive task (video encoding, raytracing) the CPU temp raises immediately to 95°-100°C

    And I do get some worrying warning messages in dmesg and in /var/log/mcelog:

    MCE 0

  • following up: I finally called dell support, telling that my temperature reaches 100° as soon as I launch some heavy computation. They changed motherboard + heatsink and now it's much better: under stress, temperature will usually stabilize

    at 85° instead of 100°.

    This makes me conclude that

    1. 100° is NOT ok

    2. Dell knows that some laptops have temp issues

  • After replacement, do you see the throttling events anymore?

    My stabilized peak CPU temperatures average between 85C and 90C, but spikes can approach 100C relatively often which triggers throttling. I reach throttling temperatures periodically during cpu-intensive tasks/builds/games.

  • I have also asked directly to DELL support, they have said that it is normal, but I cannot agree with everyday Dmesg warnings like this:

    [lun jun 26 22:24:46 2017] CPU1: Package temperature above threshold, cpu clock throttled (total events = 7570)

    [lun jun 26 22:24:46 2017] CPU2: Package temperature above threshold, cpu clock throttled (total events = 7570)

    [lun jun 26 22:24:46 2017] CPU0: Package temperature above threshold, cpu clock throttled (total events = 7570)

    Any forum senior member can share it's opinion. I have bought the "best" notebook to avoid this kind of issues and at now my feeling is I have taken the wrong decision...

  • @julioarguello

    I had these warnings regularly in dmesg too, but after they changed the motherboard + heatsink

    these warnings have disappeared. It's only one week, so maybe I should make more tests to be sure.

    The worse temp I had was when using kdenlive for rendering to mp4 files. The temp was steadily between 97° and 100° (I think the warnings occurred when reaching 101] or more, which happened every 5-10 mins during the computation).

    After Dell service last week, temps is about 85° for the same computation, and I have no warnings.

    Of course I need to make more tests...

    Fingers crossed...

  • Thanks @vns35,

    The TJUNTION temperature in the specs is 100º (ark.intel.com/.../Intel-Core-i7-7500U-Processor-4M-Cache-up-to-3_50-GHz-)

    According to the definition (www.intel.co.uk/.../000005597.html):

    "Tjunction Max is the maximum temperature the cores can reach before thermal throttling is activated. Thermal throttling happens when the processor exceeds the maximum temperature. The processor shuts itself off in order to prevent permanent damage. Tjunction Max (Tj Max) is also referred to as TCC Activation Temperature in certain processor datasheets."

    So, in my case reaching temperatures over 100º after a single compilation is not normal.

  • FTR I gave up with the device: issues with virtualisation, bad Ubuntu experience and burning temps.

    Dell support was a pain to talk to (I had ~4 different people I had to explain my problem to and mail chains with 10+ people, that was ridiculous).

    All the while paying for the pro insurance / support.

    I wasted a month, had to buy another device in urgence for a business trip and now it's sitting on my desk reminding me of the waste of time and money. Until I waste more time selling something I haven't use for half the price.

  • @julioarguello

    it's good that you found these specs. I agree with you that reaching 100° so quickly is not normal.

    if you have mce installed, you can also check

    cat /var/log/mcelog

  • @Julioarguello and lsenta,

    Send me friend requests with your service tags. We'll work together to find solutions for you both.

    I may want to obtain product captures on this if more owners come forward. However, my assumption is that this is not a very wide spread issue. New reports may just need to be handled on a case-by-case bases by calling Dell technical support.

    If I find that this is more wide spread and potential product captures reveal a problem, I can escalate that and get a solution from Dell engineering. I would probably need at least 5 units captured in order to make that case. A successful case would result in the creation of a knowledge base article with ID number that I could then share with the Community, in order that owners can get support more quickly.

    I may need Community help to make that case.

  • In case it can help, here is the temperature graph, BEFORE and AFTER Dell service change motherboard + heatsink. You can see a heavy computation (kdenlive) start at the middle of the graph.

    (same computation in both cases)

    Before: Temp reaches immediately 100°.

    After: Temp reaches 85°

  • I would like to participate and see if my XPS 13 has any temperature issues
