The temperature will get higher and higher (yes, higher than usually) .-) > Is there a security to that will increase > the fan speed automatically? No. If it's in manual mode, it's in manual mode. I don't think the SMC controller will take care of that (I just tried it now, maybe there is a protection). > The CPU will just reset using its > internal temperature protection? > Probably the system will first slow down (throttle), and then hang if the temperature is too high.

So I'm quite sure the CPU won't burn, as it has a temperature sensor integrated in the chip. For the GPU, I don't know, but I suppose (and hope) it is the same.
