I'd imagine you have doubled the power input, and the heat output of the cpu, and I'm wondering how long it itself will survive, not to mention the power regulation circuitry for the cpu with its at least doubled current drain. Heat management in a laptop is probably the highest paid engineering job at the laptop makers R&D shop, and much of that stuff is designed right down to the gnats eyebrow for cooling. I think in the interests of decent life for both the laptop and its battery, I'd put it back to the factory speed. The laptop is too valuable to cook trying to make up some bragging rights, do that to a $300 dollar Wallmart box instead. >I am now wondering if the patch applied to use ACPI rather than PST > structure is not breaking processor fan and internal fan usage of > the system which could increase the overall temperature of the > system.
