A good reference for you overclockers, here is an old but useful list of CPU's and their max operating temps. It goes all the way back to the AMD K5 processors and Intel 486 (not that many users have those anymore).

All of the information contained on this page came directly from the various datasheets provided online. Links to the datasheets are provided at the bottom of the page. Since not all of the pertinent information is clearly spelled out in the datasheets, some of the numbers were calculated using formulas found in the datasheets. Where these calculations are used is clearly marked and the formulas used are also provided.
Please note that the 'Max. Case Temp.' is the maximum temperature allowable as measured on the exterior of the processor package in the middle directly above the chip die (under the heatsink). It is not the maximum internal ambient temperature of the system enclosure. The term 'case' refers to the processor's package, not the system case. For that, AMD suggests:
"The environmental specifications on most systems guarantee operation for external ambients up to 35°C. Most PC chassis/system boxes result in a 10°C increase in temperature over the external ambient temperature. In general, this means the thermal solution should be designed to allow an internal ambient (TA) of 45°C."
