    Hi all, after a HDD failure, I'm trying to get my VPCSE Vaio working.
    I took the chance to investigate on the fan noise produced by the PC at the slightest increase of load, like a taking off airplane...
    I noticed that the internal temperatures seems quite high to me.
    The Speedfan utility reports (with the PC in idle):
    43º for the HDD (that's fine)
    61º as Temp1
    55º for the GPU
    60º for the cores 0 and 1
    Under load I saw it going almost instantly up to 75-80º, which seems quite high to me.
    Beside the noise, I have some instability on the AMD video driver, which gets quite often reset by Win7.
    Do you think that the temperature is too high?
    What could I do to fix it? I guess disassembly the entire PC is the only way, that's not too scaring, but removing the heatsink on a laptop is something I have never done...

    When the fan is going full blast, is the air blowing out strongly? You should be able to feel it at least 4 inches away. If not, you need to clean the air vents and/or lubricate the fan shaft with grease.

    Is the air blowing out hot? If not, then the heatsink is not making proper contact with the CPU and GPU. You'll need to change the thermal paste.

    Hi again, I have tried to check those two thing but it is not as easy as it seems...
    The problem is that the back of the screen, when opened, covers almost completely the air output (great design, really...) and it is almost impossible to feel the air flow even with the fan at max speed.
    You can see it in this image:

    the central part of the back of the screen slides in front of the air output

    as you can see in this other image.

    So, the air is coming out, yes. It is hot... well, not at 80º for sure, but it is not cold either. I can tell you that the laptop is extremely clean, it has been used very little in the last two years and I seriously doubt that there is any dust or that the fan needs grease (it is turning... I can hear it, a lot!).
    What I would like to understand is if these temperatures for a I7 are normal, because I have the feeling that there is some problem in the contact between the CPU/GPU and the heatsink, but I would like to avoid dismounting the entire computer just to see that everything is ok.
