10C says nothing. Is it from 190C to 180C under -120C ambient?

The delta between ambient(case) temperature and the CPU temperature would help more. If the delta for TRUE is e.g. 33C, and this drops it to 23C..... Then again, if the delta is 95C and this drops it to 85C, then the performance increase isn't THAT remarkable.

Oh and for the hypocrites, and as you can see, my values are intended not to be practical, so don't even think about picking on that.
