You can check the specifications of your particular CPU at www.cpu-world.com which details the maximum operating temperature for many processors. In general you should consider 60 degrees Celcius the absolute maximum for long periods, but aim for 45-50 degrees to be safe.e're not talking about room temperature. Most CPU run over 100 degrees fahrenheit. The link that Jim Martin gave for http://www.cpu-world.com/ gives all the information on CPU temperatures.
