The maximum recommended temperature for the Intel Core i5-2435M is 100 degrees Celsius.
You can double check this information at:
As long as the processor does not run above 100 degrees Celsius, it will be running under thermal specifications.
If the processor runs above 100 degrees Celsius, and the processor came pre-installed on your MacBook* system, I would suggest contacting them for any warranty option.
So I will watch my CPU temperature and when it's over 100 degrees Celsius I will contact Apples customer service.
But just for my curiosity; will the temperature drop when I disable Hyperthreading (because the CPU is more idle than before) or if I disable Turboboost (no automatic overclocking)?
