Secondly once the part exceeds the temperature spec, it would start to throttle by itself. So, the performance does not remain the same anymore. </P> Wed, 27 Oct 2010 22:24:37 GMT Chakravart_A_Intel 2010-10-27T22:24:37Z https://community.intel.com/t5/Embedded-Server/How-does-higher-temperatures-than-given-influences-MTBF-lifetime/m-p/242593#M162 <P>Hi, We are currently developing a new platform using an Intel Xeon CPU. Our long time temperature measurements shows an average surface temprature of ~81° Celcius. Accourding the corresponding documentation the given MTBF is valid for a surface temprature of 67.5°C. My question now is how these 15°-20° C avarage higher temperature influences the MTBF and/or lifetime of the CPU. with regards, Dierk</P> Wed, 27 Oct 2010 18:35:12 GMT https://community.intel.com/t5/Embedded-Server/How-does-higher-temperatures-than-given-influences-MTBF-lifetime/m-p/242593#M162 idata 2010-10-27T18:35:12Z https://community.intel.com/t5/Embedded-Server/How-does-higher-temperatures-than-given-influences-MTBF-lifetime/m-p/242594#M163 <P>It is almost impossibe to get the numbers that are beyond the Spec limits.
