What are the most vunerable parts of the motherboard relating to heat ?

  1. I am starting to wonder:

    1. What are the most vunerable parts of the motherboard relating to heat ?

    I see cpu chips survive 100 degrees celcius... I see gpu chips survive 90
    degrees celcius.

    However it seems the motherboard dies easily after 1 year of running at 55
    degrees or so during summer time.

    Why is it that the motherboard can't handle higher temperatures ?

    Which components on the motherboard are most likely to fail first because of
    heat ?

    2. Would it be possible for motherboard manufacturer's to make more
    heat-reliable motherboards ?

    Or is there some kind of problem ?

    Maybe it's not the motherboard manufacturers problem ?

    Maybe the people who make the little thingies have their heads in their
    butts and are making crappy shit.

    Please make better shit :)

    Bye,
    Skybuck.

    Probably electrolytic caps - they are usually the first to fail; heat
    causes them to dry out.

    Voltage regs with poor heatsinks will often be next.

    Some North Bridge chips also run hot and are not always fitted with
    heatsinks/fans.
    Yes...

    It's demand v cost.

    I guess there is 'limited demand' for this; although anyone who has
    served in Iraq, trying to get IT kit to work without air-con can see a
    demand.... ;-)

    There are also many industries (oil + gas, surveying + exploration,
    nautical etc.) who would benefit from 'ruggedised' PCs.

    Domestic /commercial PCs expect to operate within 'reasonable' temp
    limits - it's specified in the manual.

  3. 55 degrees was the temperature of the motherboard.. outside it was at most
    25.5 degrees celcius or so.

    I am also starting to wonder. Were you born retarded or did it result
    from an accident?
