    Hello,
    I am owner of the Acer 3820TG-434G64n (i5-430m, ATI HD5650) and I'm getting really high temps in load.

    My CPU is going to 100 °C then underclock itself until it reached around 85 °C.
    My GPU is going to 110 °C and sometimes it crash my system.

    I'm going to open the laptop and clear it from dust. Do you guys think, that changing the thermal grease will have significant effect? Or is cleaning from dust enough?

    Thank you.

    You are going to need to open it anyway, so there's no reason to stop half way - do both.
    These are factory assembled so it's extremely unlikely that you would do a more sloppy job than Acer applying the paste and if you buy a quality thermal compound you will improve the temps even more.

    Given your temps, any thermal paste you had on the CPU/GPU is fried. While its open I would do both. I heartily recommend IC Diamond 7 for the 3820TG. It dropped my temps 10C. Don't get your hopes up too high until you see some significant drop in temps because those temps are quite high and may indicate a loss of the cooling fluid in the heat sink to transfer heat properly. Do you get a hair dryer effect from your vents?

    I do miss my old 3820TG at times.

    Hello guys,
    thank you for reply. I used Arctic Cooling MX-2 and the temperatures dropped.

    Thank you once again :)
