    Notebook cooling (busted thermal pad)

    Just recently I went through upgrading the processor in my 6860fx. After having 1 chip come DOA then getting an x9000, I've taken out the heatsink quite a few times.

    There is another chip about the same size as the cpu that is also connected to the heatsink by a thermal pad. Is this the GPU? and if so, would it be safe to apply some AS5 to it to keep it cool. The thermal pad on it is getting worn out, and sometimes folds over itself when I put the heatsink back on, causing a huge airpocket. I'm thinking that this is the gpu since I've seen a considerable jump in my gpu temps on Everest.

    It used to idle at about 40C and go up to about 70C under load.
    Now it idles at about 55-60C and goes up to 80-85C under load.

    its not the gpu. the gpu is on the other side of the notebook.
    this might help, dunno why your gpu temp are up

    that would be the northbridge, and does not affect the GPU cooling. just make sure the laptop is raised and that thermal pad is on properly.

    Nope, that's your chipset. The thermal pad on my chipset ripped the first time I removed the heatsink. Since I didn't have a spare pad laying around I just tossed some AS5 on there. I put more than you'd normally put on a cpu since the gap is a little larger. It's been......many months since then. No BSOD because of that. Chipset hangs around 50C, cpu and gpu temps haven't changed much because of that, nor should they.

    Edit: Well as narsail said, it's the northbridge (wth is that?). I'll just go be delusional by myself and call it a chipset.

    Don't feel bad because it is a chipset; it's the PM965 northbridge. It links your cpu, memory, southbridge, and GPU. It won't directly cause your GPU to heat up. But because the heat isn't being drawn away from the northbridge it could cause the motherboard to overheat. This will cause high temp readings on the internal die thermal sensors and/or external motherboard thermal sensors.

    The result could be an interrupt, enable throttling, or forced system shutdown.

    Dear All,

    Seem like i can't find the place to buy a copper sheet with 1mm thickness. Can anyone sell one to me please. desperately looking for one. Thanks
