Thanks for all your responses
I am using the regular stock cooler as mentioned previously. I checked the temp in the BIOS, however this temp is not that accurate since the CPU is not doing much during this period. I will check again just before shutting down my PC.
I think it is a good idea to try another temp monitor. I will try that as well.
I now used the Intel Processor Diagnostic Tool which went through the tests and came up with a result of 15-17 degrees below max temp on full load. That seems strange given some of you have said the max Tcase temp is 60.1 degrees C. Any ideas here?
