GRT816S shuts down on its own will

[bsg]

My GRT 816S laptop shuts down suddenly while I'm using it, plus it's extremely hot. and it's nine months old only.
I've just set the screen luminosity to a lower value and it seems to shut down a bit less.

the temperature reaches 92°C.

Can you feel any air exhaust from the fan?
My GRV516G iP4 2.4GHz desktop CPU reaches max 65°C under sustained load.
I think >90°C is result of a cooling deficiency.

I can feel air coming out from the bottom fan, but anyway this is a severe cooling deficiency and hopefuly the machine is going to vaio link within a few days.
