  • CPU temperature running high.

    From David@21:1/5 to All on Sat May 3 16:02:44 2025
    HW monitor reports them going over 80C

    Whilst this is in range (allegedly) it is a lot higher than I remember.
    I was expecting somewhere over 40C.

    Shutting down now to investigate.

    Possible new paste for CPU heat sink.

    Possible new CPU cooler.

    Possible glitch in the variable fan speed.

    All good fun.

    Cheers

    Peak CPU temps are about 95C nowadays, at which point they throttle in order
    to keep the temps under control. I would not worry about getting to 80C if it's working hard. Modern CPUs are thermally limited, ie they can burn more power doing stuff than the package can handle, so they turbo until things
    get too hot and then throttle back.

    Some basic stuff like Windows updates are 'hard work' and involve the CPU turboing up a lot.

    If it's going much above 100C then something is wrong.

    If it was hot and supposedly not doing very much, take a look at task
    manager and see if Windows updates / virus checker / rogue browser tabs are eating all your CPU.

    On some motherboards you can mess around in the BIOS and adjust the
    "cooling profile" so that the fan starts working harder at a lower
    temperature.

    That is the next stop.
    IIRC I have a cooling profile to keep the fans quiet, and a "silent"
    case fan.

    It is so long since I built this that I can't remember quite what the settings were.

    Probably worth renewing the paste anyway, as a maintenance measure.

    Interesting.
    I noted a slow down in Chrome, and checked the temperatures which were up
    in the 80s.

    I had recently started PAN and Windows live Mail.

    I stopped both, and the temperatures went down again.

    Obviously I have started PAN again.

    Watching now before I try WLM again.

    Still need to try and get the cooling more efficient.

    Cheers

    Also ...(dumb question alert !!!) I am assuming that the CPU fan is
    connected to the CPU fan header on the MOBO - mine has 3 or 4 headers
    which all look the same to me

    As far as I know.
    Been running fine for years and only recently showing problems.
    All 3 cores below 50C just now after idling over night.

    I've found number crunching (maxing out all cores) will overheat a
    desktop PC, as they seemed to be designed assuming they will not get
    sustained full load, like a server. So I get bigger coolers.
