I'd still call that a bit extreme. For example, the thermal 
specification for 3 of 4 available Core2 Duo that runs at 2.13GHz is 
61.4C, and the remaining one has it set to a bit over 60C. Which means 
that at 61.4C, Intel Thermal Monitor should kick in and use SpeedStep to 
slow down the CPU and prevent overheating.

Intel's mobile Core2 Duo versions usually have that parameter at 105C 
because they don't have integrated heat spreaders.

Core2 Quad Q8400 (non-overclocked, 2.66GHz, thermal spec: 71.4C; in a 
heated room) runs at 33C / 24C (winter/summer) here.
