Having read a number of posts regarding cpu temperatures and " should I worry if my cpu heats over 50 degrees" etc, I'd like to point out that my S1XP has hit 85 degrees during an hours worth of Doom3 or Far Cry. The processors critical temperature is 100 degrees, though the system is designed to shut itself off at 90, which has never occurred (yet).
However I am now setting my powe management settings to Fan level '4', which keeps the temperature down to a maximum of 75 degrees by lowering the cpu speed occasionally.
Sony have said to me that 85 degrees is within spec for this system, but I'm not taking the risk!
I would say you're right not to take the risk, you paid a lot for that notebook.
