    Objectively speaking, 90 degrees C is very hot for a graphics card. 80 degrees C or lower would be ideal. Look into possibly under-clocking it to keep the temps down, or checking your paste job.

    That said, you're asking about a very old computer, not many left.

    Hi

    Thanks for your reply.
    Since I find it quite high, but normal in some users I have seen on other forums.
    I have replaced it 2 weeks ago, since I had the card's chip replaced.
    I replaced the thermal pads, they seemed to be 1mm so I replaced them with 1mm Arctic ones.
    I also reapplied thermal paste using MX4

    Temperatures when gaming are 90ºC, that's the max it gets and around 63-67 on idle when working with the computer.

    So I wonder if this is normal for this machine and what other users have. However it will difficult as you said since not many people use this computer anymore, but it's a good one after all.

    Thanks

    It might be normal for the machine, I have tested notebooks with GPU temps that high before. However, the high temperatures are not a good thing as far as the components lasting a long time.

    Underclocking the GPU is a possibility to reduce the temps, as I noted.

    Hi

    Thank you very much.
    I actually tried Speedfan and see if I can control the fans from there, but seems they are not controllable (or I am doing something wrong)

    As soon as you exit a game, the temperature instantly drops to 75ºC. So this actually makes me wonder if the readings are correct at all.

    How could I improve the cooling system here or any other tricks I can try?
    I would like to not need to underclock the graphics card at all.

    Thanks

    Some choices for improving the thermal performance:
    --Reapply thermal paste (or try a different kind of thermal paste)
    --Use a notebook cooling pad
    --Increase the fan RPM (not possible with a lot of notebooks)
    --Undervolt/underclock the component

    What you should try is using GPU-Z to log your GPU's temperatures. Run your game for 20-30 minutes and then stop the logging. You can attach the log here and I'll take a look.
    This way we can see if the GPU is throttling back its clocks when it gets to its highest temperature.
