Hehe. I didn't expect to be answering a question on my first post.
Have you tried Intel.com itself?
IntelÂ® Coreâ„¢2 Duo Desktop Processor E6300 specifications
http://processorfinder.intel.com/detail ... spec=sl9sa
This shows 61.4C maximum thermal spec
IntelÂ® CeleronÂ® D Processor 352
http://processorfinder.intel.com/detail ... Spec=SL96P
This shows 69.2C maximum thermal spec
The processor finder on Intel.com
Bookmark the processor finder. It can be very helpful on purchases.
"Thermal Specification: The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader. For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor IntelÂ® Thermal Monitor. The Intel Thermal Monitorâ€™s automatic mode is used to indicate that the maximum TJ has been reached."
It would not surprise me at all that Core 2 is lower thermally spec'ed. The chip architecture had its origins in the mobility sector.
