    Question Jaunty Frying my motherboard????

    Hello - I have to say this sounds a bit odd but it's what I'm seeing so here goes ... I had 8.04 running on a home-made machine built around an Intel DG965WH (Core2Duo) motherboard. It was ok but I had some issues with browsing so thought I'd try an upgrade to see if it resolved them (as an aside - it looks as though it has!).

    As its a homemade box, I thought it a good idea to monitor temperature so have set up the sensors-applet gadget in my desktop panel, monitoring the CPUs and two of my discs.

    So I upgraded initially to 8.10 and straightaway noticed that the CPU temperatures were much higher than I was used to seeing: previously they had been in the 40s or occasionally 50s when pushed. Now they were going up into the 60s and 70s. Carrying on with the upgrade into 9.04 this has continued: if I let it alone, the temperature on both cores is going well into the 70s, which is not sustainable, I think.

    CPU usage is 100% on both cores: if I throttle it back by stopping tracker-indexer then the temperature drops back to around 50.

    This is not an ambient temperature problem - the disc temperatures are behaving as before, around 40.

    What seems really odd is that I have regularly pushed the CPUs to 100% before - I often use this box for processing video files - and have never seen the temp go over 70. So what's going on?

    1 - as a short term fix, what's the easiest way to stop tracker-indexer from running up each time I start?

    2 - is it possible that a change in the OS has affected the way that fans for example are being controlled?

    3 - is it possible that the temperature readings are not correct?

    Any clues much appreciated.

    THX.

    This is not a solution per se but I encountered the same problem
    right after I upgraded to a fresh install of Jaunty. The culprit
    here is the runaway tracker-indexer especially in the first minutes
    after boot. My solution was to purge tracker and replaced it with
    beagle. I "heard" that beagle has its own issues too, so I'd
    keep an eye on the processes for about a week. It's ok now.
    No hyperactive processes or overworked cpu's.

    Thanks. I have disabled (rather than uninstalled) tracker - not installed beagle or anything else because TBH my use of the desktop is fairly light (this is more of a server that I happen to want to interact with from time to time).

    I'm still puzzled about the temperature thing, though, and I'm now nervous about working it hard...

    Any other thoughts out there?

    So, disabling tracker has at least allowed me to keen the machine turned on and perform one of its functions - file serving, which is undemanding on the CPUs.

    But the other thing I want to do is to crunch video files, and sure enough every time I give it some real work to do the core temperature shoots up to 70C or more.

    This is definitely hotter than it ran under 8.04.

    Any suggestions? I am guessing that the fans are no longer being controlled as they used to be?

    Help much appreciated before I find myself having to do something drastic...

    TIA

    Have you tried monitoring your temperatures with Xsensor instead of sensor-applet ?

    Well, I just tried Xsensors and got the blank screen that others have reported ... but in any case, as I understand it, this is just another UI to sensors ... if I run that from the command line, I get the same temperatures as are being shown to me by sensor-applet, which I guess isn't surprising if they are just different interfaces to the same underlying sensors. SO even if I do persuade XSensors to talk to me, its just going to give the same numbers?

    Any other ideas as to why I'm running so much hotter than before I upgraded?

    TIA

    Ceejay:

    Have you checked the monitoring, fans, etc. related parameters in your BIOS ?

    I am now running Jaunty on the machine I am typing this on and I was previously using most of the other previous Ubuntu versions on and if anything Xsensors shows the CPU and M/B temperatures lower than when running previous versions of Ubuntu !!!

    Hi

    thanks for the response. Yes, I've had a look in the BIOS - there isn't a lot to play with there, but it seems to be correctly set up. I have made a few changes to see what happens but no obvious effect.

    What is really striking me is the very obvious and immediate change in temperatures as I went from 8.04 to 8.10 (as an intermediate step to 9.04). I'm wondering whether its a specific issue with my motherboard (Intel DG965WH) ... in which case it might take me a while before I find someone else with the same setup!

    Thanks

    Did I ask if your BIOS is on the latest and greatest version ?

    No, I don't think you did ask if I had the latest BIOS ... but if you had, it would have been a good question, thanks for reminding me!

    I had a look and sure enough there is a significantly newer BIOS. As always the release notes don't list anything that exactly matches, but there is something just close enough to make you think its worth a try!

    So I have now updated the BIOS to the latest and greatest ... and its made precisely no difference.

    More ideas?

    ATM I've got a box which I don't feel at all confident about leaving running overnight running intensive rendering batch jobs, which I would like to be able to do!!

    TIA
