The temperature depends on the rating of the CPU and is marked on the chip as a part of the ID. number. . If AMD say your chip limit is 85C. that is the MAX that it could safely run at but it is not recommended.
If you overclock you will get a higher running temperature but it still should not exceed the max. .would not recomend running any higher than 75% of the MAX rating of the CPU
There is a big difference between nominal operating temperature and what is an absolute maximum limit. 85 degrees is the temperature above which the chip will suffer permanent damage.
However it is always wise to run at much lower temperatures. This is partly because chips are more efficient at lower temperatures. It is also so that you have a good margin of safety.
For example, last summer some systems got dangerously close to their limits because the ambient temperature was so high. And of course you always have the problem of heat sinks gradually becoming clogged with dust. A processor running at 65 degrees under ideal conditions could rise markedly with a change in the weather.
Also there is considerable variation between different motherboards as far as temperature sensing goes. The temperatures reported are rarely excact.
Thanks for the feedback chaps, but as I said my system core temperature appears to be 55C to 60C with a system temperature of 30C thats 50% higher than overclockers ceiling. Just in case you're wondering I also have a ultra efficent viariable speed Cooler Master CPU fan.
