Go to gamer-debate.com, enter your CPU description and you'll get a page that tells you technical details on your CPU including maximum operating temp. Having been there, I can say that most overclockers are doing gradual damage to their CPU. Some of the hottest and notoriously fastest CPU's have lower maximum operating temps than you would expect. For example, the i7-3039k Sandy Bridge Extreme processor, with 6 cores and 12 logical threads, known to be fast, has a maximum temp of 65C, or 149F.
That a far cry from the 95C (201F). There is a reason that more expensive versions of processors from the same family have lower clock speeds. Its because of heat building up in the processor due to its increase in mass and an increase in TDP (Total Draw Power). Every watt is 3.413 additional BTU's of heat. A BTU of heat raises 1 lb of water 1 degree F. If a CPU's TDP is 105 watts, that is 105 x 3.413 = 358 BTU's per hour. When the CPU is being pushed, several cores are processing and temperature rises exponentially because the activity demand and power draw has risen exponentially, the heat sink, its contact, and its transfer of heat better be as immediate and as exponential as the demand requires. In this regard, more heat removal is better, more care and conservatism is better.
