If you do not hesitate to step in to a world of ignorance and Stockholm syndrome then you might want to read this thread.

At the end you'll find posts telling that OS X update 10.6.7 have fixed all problems.

Still you might wonder how anyone could consider cpu temperatures at 99 °C to be fixed.

If in doubt you should recall those magical words from Apple "it is not a flaw... it is an feature"

FYI Core i7 Sandy Bridge mobile processors max temperature (as told by Intel) is 100 °C and way before reaching the maximum temperature the CPU starts to lower its clock speed.

Apple have decided to add a substantial one (1) degree Celsius marginal between thermal shutdown and operating temperature.

Happy macbooking!
