    Hello.

    A friend of mine purchased my previous laptop, the G73JW.

    He doesn't play much, and have been using it mostly as a media pc recently.

    For the last 2 months he has complained about the laptop just shutting down in the middle of media streaming and that it gets very hot.

    Thermal readings when idle in windows shows

    CPU, all cores at 70-80 degrees
    GPU, 55 - 60 degrees

    We suspected faulty fans and disassembled the thing. The fans worked it seemed, and running furmark without any cover showed GPU to max out at 83 degrees and rock stable.

    Assembling it again and the GPU reached 96 degrees before I hit ESC on furmark.

    So the fans are alright supposedly and the dust is removed.

    What can cause this? Bad contact between heatsink and CPU/GPU? Software? Bios/motherboard issues?

    I have already emailed the vendor about this problem and probably need to send it to repairs.

    If the fans are working fine and everything is clean, then it probably is degraded thermal paste. however, your issue sounds like dust clogged heatsinks, you mentioned you checked the fans, but did you also check the heatsinks?

    We didn't dissasemble it down so much that we saw the entire heatsink, but we did remove the visible dust that we could see from above and by the fans.

    There wasn't that much dust so it didn't strike me as a main cause. Could try to blow some pressured air through the vents back and see if that clears it up.

    Do so, you could be surprised at the amount of dust that can come out of there. If the fans are full of dust, then that means that you probably dust bunnies everywhere in the heatsinks, if you see very little dust in the fan, doesn't mean the heatsinks are clean, but it means that compressed gas will remove most of it.

    how You remove dust? Blow one can of air into rear vents.Than open bottom cover and blow dust from inside.

    If you can completely remove off the heatsinks then you can make it a new one,
    what I did for my toshiba f20 heatsink is, took the heatsink out and kept it dumped inside a water bowl for some time the the dust particles was floating, and I opend the tap and kept the vents washing throughout the water ( I mean the heatsink vents)
