    Only 3 days old but the 1440x900 bugged me too much so I worked a deal for a display model with a 1920x1200 screen. Everything is fine except now my temps for the gpu are about 10 degrees higher under load, no big deal but still...should I reseat gpu with some AS5? Anyways 63 maxxed to 73 maxxed now at same rez 1280x800 testing. I know 75 is fine but what are you guys seeing for your temps?

    reseating the GPU is not a minor operation, requires complete disassembly of the notebook. Did you try propping up the back of the notebook just slightly (book, pack of playing cards, anything like that is more than enough)? 73 isn't too bad but it's on the warm side compared to some I've seen.

    I wouldn't recommend using AS5 or any other thermal paste on the GPU as it comes with a thermal pad.

    It does? :confused: I think he means refixing the heatpipe to the GPU with some new thermal paste, not actually removing the GPU (which, I believe is soldered to the motherboard).

    The heatpipe for the CPU and GPU is easily removed by removing the access cover on the bottom. 10 minutes in and out. BUT (as BobXX stated), since the GPU uses a thermal pad and not compound, the two are not interchangeable...the pad is much thicker than the AS5 compound would be.

    But, if you have some AS5, it certainly wouldn't hurt to apply some to the CPU (after cleaning off the factory crap, of course!).

    under the normal access is the CPU and Chipset. Do not remove the pad on the chipset. There is a gap between the chipset and heatsink . I just did a 24 hour test replacing the heat pad with AS5 and can tell you the paste never squished on the chipset leaving it thick there with NO pressure between the heartsink and chipset chip. over time this will cause issues!!!!!!!!!!!!

    That is NOT the GPU, it's the CPU and chipset. The GPU is further to your left and closer to the front when your looking at the laptop. It requires complete disassembly to get to it. You can see the GPU heatsink on the left behind the dvd drive.
