Thread: Heat problem

    Default Heat problem

    I'm running Suse 11.1 on a Foxconn motherboard equipped with an AMD Athlon 64 3200+ (AM2). Every time when the screen saver appears, the processor temperature runs sky high, I hear the CPU-fan accellerate but it cannot prevend the CPU from reaching its temperature limit and the computer from switching off. 'My computer' indicates a normal working temperature of about 25 degrees C, but when switching off it has risen to 75. I assume real temperature will be at least 10 degrees higher. What can be the reason and how can I change this unwanted behaviour?

    Which screensaver? and does it do it with all?


    First thing I would look at is your heatsink and fan, make sure they are
    seated properly and that there is good contact ( thermal paste ) you should
    not see a temp increase by that much no matter what may be running in the
    background.

    How do you know that the temp is that high. how are you monitoring it?


    What runs when the screensaver starts?

    everything baskitcaise/Mark wrote is important...this is additional:

    until you know what is going wrong: pick a different screen saver or
    turn off screen saver completely..

    screen savers came into existence a million years ago when all we had
    were cathode ray tubes which would "burn in" any image which was
    constantly displayed....that doesn't happen anymore and therefore
    screen savers are nothing more than energy wasters, requiring lots of
    cycles to draw pretty/moving pix..

    i suggest you pick "blank screen" as your screen saver and help save
    the planet..

    and, clean out the cat hair and cob webs in your cabinet--and, i have
    to put *new* thermal compound/grease/paste between the heat sink and
    CPU about every two years--READ how to do it, more is NOT
    better.....here is some info for you:

    ymmv!

    Also make sure "cool&quiet" is enabled in BIOS.
